Overview

Constructs a service interface object. Each API operation is exposed as a function on service.

Service Description

Note: This is AWS WAF Classic Regional documentation. For more information, see AWS WAF Classic in the developer guide. For the latest version of AWS WAF, use the AWS WAFV2 API and see the AWS WAF Developer Guide. With the latest version, AWS WAF has a single set of endpoints for regional and global use.

This is the AWS WAF Regional Classic API Reference for using AWS WAF Classic with the AWS resources, Elastic Load Balancing (ELB) Application Load Balancers and API Gateway APIs. The AWS WAF Classic actions and data types listed in the reference are available for protecting Elastic Load Balancing (ELB) Application Load Balancers and API Gateway APIs. You can use these actions and data types by means of the endpoints listed in AWS Regions and Endpoints. This guide is for developers who need detailed information about the AWS WAF Classic API actions, data types, and errors. For detailed information about AWS WAF Classic features and an overview of how to use the AWS WAF Classic API, see the AWS WAF Classic in the developer guide.

Sending a Request Using WAFRegional

var wafregional = new AWS.WAFRegional();
wafregional.associateWebACL(params, function (err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Locking the API Version

In order to ensure that the WAFRegional object uses this specific API, you can construct the object by passing the apiVersion option to the constructor:

var wafregional = new AWS.WAFRegional({apiVersion: '2016-11-28'});

You can also set the API version globally in AWS.config.apiVersions using the wafregional service identifier:

AWS.config.apiVersions = {
  wafregional: '2016-11-28',
  // other service API versions
};

var wafregional = new AWS.WAFRegional();

    Context (this):

    • (AWS.Response) —

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error) —

      the error object returned from the request. Set to null if the request is successful.

    • data (Object) —

      the de-serialized data returned from the request. Set to null if a request error occurs.

Returns:

  • (AWS.Request) —

    a handle to the operation request for subsequent event callback registration.

createByteMatchSet(params = {}, callback) ⇒ AWS.Request

Note: This is AWS WAF Classic documentation. For more information, see AWS WAF Classic in the developer guide. For the latest version of AWS WAF, use the AWS WAFV2 API and see the AWS WAF Developer Guide. With the latest version, AWS WAF has a single set of endpoints for regional and global use.

Creates a ByteMatchSet. You then use UpdateByteMatchSet to identify the part of a web request that you want AWS WAF to inspect, such as the values of the User-Agent header or the query string. For example, you can create a ByteMatchSet that matches any requests with User-Agent headers that contain the string BadBot. You can then configure AWS WAF to reject those requests.

To create and configure a ByteMatchSet, perform the following steps:

  1. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of a CreateByteMatchSet request.

  2. Submit a CreateByteMatchSet request.

  3. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateByteMatchSet request.

  4. Submit an UpdateByteMatchSet request to specify the part of the request that you want AWS WAF to inspect (for example, the header or the URI) and the value that you want AWS WAF to watch for.

For more information about how to use the AWS WAF API to allow or block HTTP requests, see the AWS WAF Developer Guide.

Service Reference:

Examples:

Calling the createByteMatchSet operation

var params = {
  ChangeToken: 'STRING_VALUE', /* required */
  Name: 'STRING_VALUE' /* required */
};
wafregional.createByteMatchSet(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {}) —
    • Name — (String)

      A friendly name or description of the ByteMatchSet. You can't change Name after you create a ByteMatchSet.

    • ChangeToken — (String)

      The value returned by the most recent call to GetChangeToken.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response) —

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error) —

      the error object returned from the request. Set to null if the request is successful.

    • data (Object) —

      the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

      • ByteMatchSet — (map)

        A ByteMatchSet that contains no ByteMatchTuple objects.

        • ByteMatchSetId — required — (String)

          The ByteMatchSetId for a ByteMatchSet. You use ByteMatchSetId to get information about a ByteMatchSet (see GetByteMatchSet), update a ByteMatchSet (see UpdateByteMatchSet), insert a ByteMatchSet into a Rule or delete one from a Rule (see UpdateRule), and delete a ByteMatchSet from AWS WAF (see DeleteByteMatchSet).

          ByteMatchSetId is returned by CreateByteMatchSet and by ListByteMatchSets.

        • Name — (String)

          A friendly name or description of the ByteMatchSet. You can't change Name after you create a ByteMatchSet.

        • ByteMatchTuples — required — (Array<map>)

          Specifies the bytes (typically a string that corresponds with ASCII characters) that you want AWS WAF to search for in web requests, the location in requests that you want AWS WAF to search, and other settings.

          • FieldToMatch — required — (map)

            The part of a web request that you want AWS WAF to search, such as a specified header or a query string. For more information, see FieldToMatch.

            • Type — required — (String)

              The part of the web request that you want AWS WAF to search for a specified string. Parts of a request that you can search include the following:

              • HEADER: A specified request header, for example, the value of the User-Agent or Referer header. If you choose HEADER for the type, specify the name of the header in Data.

              • METHOD: The HTTP method, which indicated the type of operation that the request is asking the origin to perform. Amazon CloudFront supports the following methods: DELETE, GET, HEAD, OPTIONS, PATCH, POST, and PUT.

              • QUERY_STRING: A query string, which is the part of a URL that appears after a ? character, if any.

              • URI: The part of a web request that identifies a resource, for example, /images/daily-ad.jpg.

              • BODY: The part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form. The request body immediately follows the request headers. Note that only the first 8192 bytes of the request body are forwarded to AWS WAF for inspection. To allow or block requests based on the length of the body, you can create a size constraint set. For more information, see CreateSizeConstraintSet.

              • SINGLE_QUERY_ARG: The parameter in the query string that you will inspect, such as UserName or SalesRegion. The maximum length for SINGLE_QUERY_ARG is 30 characters.

              • ALL_QUERY_ARGS: Similar to SINGLE_QUERY_ARG, but rather than inspecting a single parameter, AWS WAF will inspect all parameters within the query for the value or regex pattern that you specify in TargetString.

              Possible values include:
              • "URI"
              • "QUERY_STRING"
              • "HEADER"
              • "METHOD"
              • "BODY"
              • "SINGLE_QUERY_ARG"
              • "ALL_QUERY_ARGS"
            • Data — (String)

              When the value of Type is HEADER, enter the name of the header that you want AWS WAF to search, for example, User-Agent or Referer. The name of the header is not case sensitive.

              When the value of Type is SINGLE_QUERY_ARG, enter the name of the parameter that you want AWS WAF to search, for example, UserName or SalesRegion. The parameter name is not case sensitive.

              If the value of Type is any other value, omit Data.

          • TargetString — required — (Buffer, Typed Array, Blob, String)

            The value that you want AWS WAF to search for. AWS WAF searches for the specified string in the part of web requests that you specified in FieldToMatch. The maximum length of the value is 50 bytes.

            Valid values depend on the values that you specified for FieldToMatch:

            • HEADER: The value that you want AWS WAF to search for in the request header that you specified in FieldToMatch, for example, the value of the User-Agent or Referer header.

            • METHOD: The HTTP method, which indicates the type of operation specified in the request. CloudFront supports the following methods: DELETE, GET, HEAD, OPTIONS, PATCH, POST, and PUT.

            • QUERY_STRING: The value that you want AWS WAF to search for in the query string, which is the part of a URL that appears after a ? character.

            • URI: The value that you want AWS WAF to search for in the part of a URL that identifies a resource, for example, /images/daily-ad.jpg.

            • BODY: The part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form. The request body immediately follows the request headers. Note that only the first 8192 bytes of the request body are forwarded to AWS WAF for inspection. To allow or block requests based on the length of the body, you can create a size constraint set. For more information, see CreateSizeConstraintSet.

            • SINGLE_QUERY_ARG: The parameter in the query string that you will inspect, such as UserName or SalesRegion. The maximum length for SINGLE_QUERY_ARG is 30 characters.

            • ALL_QUERY_ARGS: Similar to SINGLE_QUERY_ARG, but instead of inspecting a single parameter, AWS WAF inspects all parameters within the query string for the value or regex pattern that you specify in TargetString.

            If TargetString includes alphabetic characters A-Z and a-z, note that the value is case sensitive.

            If you're using the AWS WAF API

            Specify a base64-encoded version of the value. The maximum length of the value before you base64-encode it is 50 bytes.

            For example, suppose the value of Type is HEADER and the value of Data is User-Agent. If you want to search the User-Agent header for the value BadBot, you base64-encode BadBot using MIME base64-encoding and include the resulting value, QmFkQm90, in the value of TargetString.

            If you're using the AWS CLI or one of the AWS SDKs

            The value that you want AWS WAF to search for. The SDK automatically base64 encodes the value.

          • TextTransformation — required — (String)

            Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass AWS WAF. If you specify a transformation, AWS WAF performs the transformation on FieldToMatch before inspecting it for a match.

            You can only specify a single type of TextTransformation.

            CMD_LINE

            When you're concerned that attackers are injecting an operating system command line command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:

            • Delete the following characters: \ " ' ^

            • Delete spaces before the following characters: / (

            • Replace the following characters with a space: , ;

            • Replace multiple spaces with one space

            • Convert uppercase letters (A-Z) to lowercase (a-z)

            COMPRESS_WHITE_SPACE

            Use this option to replace the following characters with a space character (decimal 32):

            • \f, formfeed, decimal 12

            • \t, tab, decimal 9

            • \n, newline, decimal 10

            • \r, carriage return, decimal 13

            • \v, vertical tab, decimal 11

            • non-breaking space, decimal 160

            COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.

            HTML_ENTITY_DECODE

            Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:

            • Replaces (ampersand)quot; with "

            • Replaces (ampersand)nbsp; with a non-breaking space, decimal 160

            • Replaces (ampersand)lt; with a "less than" symbol

            • Replaces (ampersand)gt; with >

            • Replaces characters that are represented in hexadecimal format, (ampersand)#xhhhh;, with the corresponding characters

            • Replaces characters that are represented in decimal format, (ampersand)#nnnn;, with the corresponding characters

            LOWERCASE

            Use this option to convert uppercase letters (A-Z) to lowercase (a-z).

            URL_DECODE

            Use this option to decode a URL-encoded value.

            NONE

            Specify NONE if you don't want to perform any text transformations.

            Possible values include:
            • "NONE"
            • "COMPRESS_WHITE_SPACE"
            • "HTML_ENTITY_DECODE"
            • "LOWERCASE"
            • "CMD_LINE"
            • "URL_DECODE"
          • PositionalConstraint — required — (String)

            Within the portion of a web request that you want to search (for example, in the query string, if any), specify where you want AWS WAF to search. Valid values include the following:

            CONTAINS

            The specified part of the web request must include the value of TargetString, but the location doesn't matter.

            CONTAINS_WORD

            The specified part of the web request must include the value of TargetString, and TargetString must contain only alphanumeric characters or underscore (A-Z, a-z, 0-9, or ). In addition, TargetString must be a word, which means one of the following:

            • TargetString exactly matches the value of the specified part of the web request, such as the value of a header.

            • TargetString is at the beginning of the specified part of the web request and is followed by a character other than an alphanumeric character or underscore (), for example, BadBot;.

            • TargetString is at the end of the specified part of the web request and is preceded by a character other than an alphanumeric character or underscore (), for example, ;BadBot.

            • TargetString is in the middle of the specified part of the web request and is preceded and followed by characters other than alphanumeric characters or underscore (), for example, -BadBot;.

            EXACTLY

            The value of the specified part of the web request must exactly match the value of TargetString.

            STARTS_WITH

            The value of TargetString must appear at the beginning of the specified part of the web request.

            ENDS_WITH

            The value of TargetString must appear at the end of the specified part of the web request.

            Possible values include:
            • "EXACTLY"
            • "STARTS_WITH"
            • "ENDS_WITH"
            • "CONTAINS"
            • "CONTAINS_WORD"
      • ChangeToken — (String)

        The ChangeToken that you used to submit the CreateByteMatchSet request. You can also use this value to query the status of the request. For more information, see GetChangeTokenStatus.

Returns:

  • (AWS.Request) —

    a handle to the operation request for subsequent event callback registration.

createGeoMatchSet(params = {}, callback) ⇒ AWS.Request

Note: This is AWS WAF Classic documentation. For more information, see AWS WAF Classic in the developer guide. For the latest version of AWS WAF, use the AWS WAFV2 API and see the AWS WAF Developer Guide. With the latest version, AWS WAF has a single set of endpoints for regional and global use.

Creates an GeoMatchSet, which you use to specify which web requests you want to allow or block based on the country that the requests originate from. For example, if you're receiving a lot of requests from one or more countries and you want to block the requests, you can create an GeoMatchSet that contains those countries and then configure AWS WAF to block the requests.

To create and configure a GeoMatchSet, perform the following steps:

Examples:

Calling the createGeoMatchSet operation

var params = {
  ChangeToken: 'STRING_VALUE', /* required */
  Name: 'STRING_VALUE' /* required */
};
wafregional.createGeoMatchSet(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {}) —
    • Name — (String)

      A friendly name or description of the GeoMatchSet. You can't change Name after you create the GeoMatchSet.

    • ChangeToken — (String)

      The value returned by the most recent call to GetChangeToken.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response) —

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error) —

      the error object returned from the request. Set to null if the request is successful.

    • data (Object) —

      the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

      • GeoMatchSet — (map)

        The GeoMatchSet returned in the CreateGeoMatchSet response. The GeoMatchSet contains no GeoMatchConstraints.

        • GeoMatchSetId — required — (String)

          The GeoMatchSetId for an GeoMatchSet. You use GeoMatchSetId to get information about a GeoMatchSet (see GeoMatchSet), update a GeoMatchSet (see UpdateGeoMatchSet), insert a GeoMatchSet into a Rule or delete one from a Rule (see UpdateRule), and delete a GeoMatchSet from AWS WAF (see DeleteGeoMatchSet).

          GeoMatchSetId is returned by CreateGeoMatchSet and by ListGeoMatchSets.

        • Name — (String)

          A friendly name or description of the GeoMatchSet. You can't change the name of an GeoMatchSet after you create it.

        • GeoMatchConstraints — required — (Array<map>)

          An array of GeoMatchConstraint objects, which contain the country that you want AWS WAF to search for.

          • Type — required — (String)

            The type of geographical area you want AWS WAF to search for. Currently Country is the only valid value.

            Possible values include:
            • "Country"
          • Value — required — (String)

            The country that you want AWS WAF to search for.

    a handle to the operation request for subsequent event callback registration.

createIPSet(params = {}, callback) ⇒ AWS.Request

Note: This is AWS WAF Classic documentation. For more information, see AWS WAF Classic in the developer guide. For the latest version of AWS WAF, use the AWS WAFV2 API and see the AWS WAF Developer Guide. With the latest version, AWS WAF has a single set of endpoints for regional and global use.

Creates an IPSet, which you use to specify which web requests that you want to allow or block based on the IP addresses that the requests originate from. For example, if you're receiving a lot of requests from one or more individual IP addresses or one or more ranges of IP addresses and you want to block the requests, you can create an IPSet that contains those IP addresses and then configure AWS WAF to block the requests.

To create and configure an IPSet, perform the following steps:

  1. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of a CreateIPSet request.

  2. Submit a CreateIPSet request.

  3. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateIPSet request.

  4. Submit an UpdateIPSet request to specify the IP addresses that you want AWS WAF to watch for.

For more information about how to use the AWS WAF API to allow or block HTTP requests, see the AWS WAF Developer Guide.

   */
 });

Calling the createIPSet operation

var params = {
  ChangeToken: 'STRING_VALUE', /* required */
  Name: 'STRING_VALUE' /* required */
};
wafregional.createIPSet(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

    • Name — (String)

      A friendly name or description of the IPSet. You can't change Name after you create the IPSet.

    • ChangeToken — (String)

      The value returned by the most recent call to GetChangeToken.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response) —

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error) —

      the error object returned from the request. Set to null if the request is successful.

    • data (Object) —

      the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

      • IPSet — (map)

        The IPSet returned in the CreateIPSet response.

        • IPSetId — required — (String)

          The IPSetId for an IPSet. You use IPSetId to get information about an IPSet (see GetIPSet), update an IPSet (see UpdateIPSet), insert an IPSet into a Rule or delete one from a Rule (see UpdateRule), and delete an IPSet from AWS WAF (see DeleteIPSet).

          IPSetId is returned by CreateIPSet and by ListIPSets.

        • Name — (String)

          A friendly name or description of the IPSet. You can't change the name of an IPSet after you create it.

        • IPSetDescriptors — required — (Array<map>)

          The IP address type (IPV4 or IPV6) and the IP address range (in CIDR notation) that web requests originate from. If the WebACL is associated with a CloudFront distribution and the viewer did not use an HTTP proxy or a load balancer to send the request, this is the value of the c-ip field in the CloudFront access logs.

          • Type — required — (String)

            Specify IPV4 or IPV6.

            Possible values include:
            • "IPV4"
            • "IPV6"
          • Value — required — (String)

            Specify an IPv4 address by using CIDR notation. For example:

            • To configure AWS WAF to allow, block, or count requests that originated from the IP address 192.0.2.44, specify 192.0.2.44/32.

            • To configure AWS WAF to allow, block, or count requests that originated from IP addresses from 192.0.2.0 to 192.0.2.255, specify 192.0.2.0/24.

            For more information about CIDR notation, see the Wikipedia entry Classless Inter-Domain Routing.

            Specify an IPv6 address by using CIDR notation. For example:

            • To configure AWS WAF to allow, block, or count requests that originated from the IP address 1111:0000:0000:0000:0000:0000:0000:0111, specify 1111:0000:0000:0000:0000:0000:0000:0111/128.

            • To configure AWS WAF to allow, block, or count requests that originated from IP addresses 1111:0000:0000:0000:0000:0000:0000:0000 to 1111:0000:0000:0000:ffff:ffff:ffff:ffff, specify 1111:0000:0000:0000:0000:0000:0000:0000/64.

      • ChangeToken — (String)

        The ChangeToken that you used to submit the CreateIPSet request. You can also use this value to query the status of the request. For more information, see GetChangeTokenStatus.

Returns:

  • (AWS.Request) —

    a handle to the operation request for subsequent event callback registration.

createRateBasedRule(params = {}, callback) ⇒ AWS.Request

Note: This is AWS WAF Classic documentation. For more information, see AWS WAF Classic in the developer guide. For the latest version of AWS WAF, use the AWS WAFV2 API and see the AWS WAF Developer Guide. With the latest version, AWS WAF has a single set of endpoints for regional and global use.

Creates a RateBasedRule. The RateBasedRule contains a RateLimit, which specifies the maximum number of requests that AWS WAF allows from a specified IP address in a five-minute period. The RateBasedRule also contains the IPSet objects, ByteMatchSet objects, and other predicates that identify the requests that you want to count or block if these requests exceed the RateLimit.

If you add more than one predicate to a RateBasedRule, a request not only must exceed the RateLimit, but it also must match all the conditions to be counted or blocked. For example, suppose you add the following to a RateBasedRule:

  • An IPSet that matches the IP address 192.0.2.44/32

  • A ByteMatchSet that matches BadBot in the User-Agent header

Further, you specify a RateLimit of 1,000.

You then add the RateBasedRule to a WebACL and specify that you want to block requests that meet the conditions in the rule. For a request to be blocked, it must come from the IP address 192.0.2.44 and the User-Agent header in the request must contain the value BadBot. Further, requests that match these two conditions must be received at a rate of more than 1,000 requests every five minutes. If both conditions are met and the rate is exceeded, AWS WAF blocks the requests. If the rate drops below 1,000 for a five-minute period, AWS WAF no longer blocks the requests.

As a second example, suppose you want to limit requests to a particular page on your site. To do this, you could add the following to a RateBasedRule:

  • A ByteMatchSet with FieldToMatch of URI

  • A PositionalConstraint of STARTS_WITH

  • A TargetString of login

Further, you specify a RateLimit of 1,000.

By adding this RateBasedRule to a WebACL, you could limit requests to your login page without affecting the rest of your site.

To create and configure a RateBasedRule, perform the following steps:

  1. Create and update the predicates that you want to include in the rule. For more information, see CreateByteMatchSet, CreateIPSet, and CreateSqlInjectionMatchSet.

  2. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of a CreateRule request.

  3. Submit a CreateRateBasedRule request.

  4. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateRule request.

  5. Submit an UpdateRateBasedRule request to specify the predicates that you want to include in the rule.

  6. Create and update a WebACL that contains the RateBasedRule. For more information, see CreateWebACL.

For more information about how to use the AWS WAF API to allow or block HTTP requests, see the AWS WAF Developer Guide.

      Value: 'STRING_VALUE' /* required */
    },
    /* more items */
  ]
};
wafregional.createRateBasedRule(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {}) —
    • Name — (String)

      A friendly name or description of the RateBasedRule. You can't change the name of a RateBasedRule after you create it.

    • MetricName — (String)

      A friendly name or description for the metrics for this RateBasedRule. The name can contain only alphanumeric characters (A-Z, a-z, 0-9), with maximum length 128 and minimum length one. It can't contain whitespace or metric names reserved for AWS WAF, including "All" and "Default_Action." You can't change the name of the metric after you create the RateBasedRule.

    • RateKey — (String)

      The field that AWS WAF uses to determine if requests are likely arriving from a single source and thus subject to rate monitoring. The only valid value for RateKey is IP. IP indicates that requests that arrive from the same IP address are subject to the RateLimit that is specified in the RateBasedRule.

      Possible values include:
      • "IP"
    • RateLimit — (Integer)

      The maximum number of requests, which have an identical value in the field that is specified by RateKey, allowed in a five-minute period. If the number of requests exceeds the RateLimit and the other predicates specified in the rule are also met, AWS WAF triggers the action that is specified for this rule.

    • ChangeToken — (String)

      The ChangeToken that you used to submit the CreateRateBasedRule request. You can also use this value to query the status of the request. For more information, see GetChangeTokenStatus.

      • Key — required — (String)

      • Value — required — (String)

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response) —

      the response object containing error, data properties, and the original request object.

    Parameters:

          • "IP"
        • RateLimit — required — (Integer)

          The maximum number of requests, which have an identical value in the field specified by the RateKey, allowed in a five-minute period. If the number of requests exceeds the RateLimit and the other predicates specified in the rule are also met, AWS WAF triggers the action that is specified for this rule.

      • ChangeToken — (String)

        The ChangeToken that you used to submit the CreateRateBasedRule request. You can also use this value to query the status of the request. For more information, see GetChangeTokenStatus.

createRegexMatchSet(params = {}, callback) ⇒ AWS.Request

Note: This is AWS WAF Classic documentation. For more information, see AWS WAF Classic in the developer guide. For the latest version of AWS WAF, use the AWS WAFV2 API and see the AWS WAF Developer Guide. With the latest version, AWS WAF has a single set of endpoints for regional and global use.

Creates a RegexMatchSet. You then use UpdateRegexMatchSet to identify the part of a web request that you want AWS WAF to inspect, such as the values of the User-Agent header or the query string. For example, you can create a RegexMatchSet that contains a RegexMatchTuple that looks for any requests with User-Agent headers that match a RegexPatternSet with pattern B[a@]dB[o0]t. You can then configure AWS WAF to reject those requests.

To create and configure a RegexMatchSet, perform the following steps:

  1. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of a CreateRegexMatchSet request.

  2. Submit a CreateRegexMatchSet request.

  3. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateRegexMatchSet request.

  4. Submit an UpdateRegexMatchSet request to specify the part of the request that you want AWS WAF to inspect (for example, the header or the URI) and the value, using a RegexPatternSet, that you want AWS WAF to watch for.

For more information about how to use the AWS WAF API to allow or block HTTP requests, see the AWS WAF Developer Guide.

Examples:

Calling the createRegexMatchSet operation

var params = {
  ChangeToken: 'STRING_VALUE', /* required */
  Name: 'STRING_VALUE' /* required */
};
wafregional.createRegexMatchSet(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred

      A friendly name or description of the RegexMatchSet. You can't change Name after you create a RegexMatchSet.

    • ChangeToken — (String)

      The value returned by the most recent call to GetChangeToken.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response) —

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error) —

      the error object returned from the request. Set to null if the request is successful.

    • data (Object) —

      the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

      • RegexMatchSet — (map)

        A RegexMatchSet that contains no RegexMatchTuple objects.

        • RegexMatchSetId — (String)

          The RegexMatchSetId for a RegexMatchSet. You use RegexMatchSetId to get information about a RegexMatchSet (see GetRegexMatchSet), update a RegexMatchSet (see UpdateRegexMatchSet), insert a RegexMatchSet into a Rule or delete one from a Rule (see UpdateRule), and delete a RegexMatchSet from AWS WAF (see DeleteRegexMatchSet).

          RegexMatchSetId is returned by CreateRegexMatchSet and by ListRegexMatchSets.

        • Name — (String)

          A friendly name or description of the RegexMatchSet. You can't change Name after you create a RegexMatchSet.

        • RegexMatchTuples — (Array<map>)

          Contains an array of RegexMatchTuple objects. Each RegexMatchTuple object contains:

          • The part of a web request that you want AWS WAF to inspect, such as a query string or the value of the User-Agent header.

          • The identifier of the pattern (a regular expression) that you want AWS WAF to look for. For more information, see RegexPatternSet.

          • Whether to perform any conversions on the request, such as converting it to lowercase, before inspecting it for the specified string.

          • FieldToMatch — required — (map)

            Specifies where in a web request to look for the RegexPatternSet.

            • Type — required — (String)

              The part of the web request that you want AWS WAF to search for a specified string. Parts of a request that you can search include the following:

              • HEADER: A specified request header, for example, the value of the User-Agent or Referer header. If you choose HEADER for the type, specify the name of the header in Data.

              • METHOD: The HTTP method, which indicated the type of operation that the request is asking the origin to perform. Amazon CloudFront supports the following methods: DELETE, GET, HEAD, OPTIONS, PATCH, POST, and PUT.

              • QUERY_STRING: A query string, which is the part of a URL that appears after a ? character, if any.

              • URI: The part of a web request that identifies a resource, for example, /images/daily-ad.jpg.

              • BODY: The part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form. The request body immediately follows the request headers. Note that only the first 8192 bytes of the request body are forwarded to AWS WAF for inspection. To allow or block requests based on the length of the body, you can create a size constraint set. For more information, see CreateSizeConstraintSet.

              • SINGLE_QUERY_ARG: The parameter in the query string that you will inspect, such as UserName or SalesRegion. The maximum length for SINGLE_QUERY_ARG is 30 characters.

              • ALL_QUERY_ARGS: Similar to SINGLE_QUERY_ARG, but rather than inspecting a single parameter, AWS WAF will inspect all parameters within the query for the value or regex pattern that you specify in TargetString.

              Possible values include:
              • "URI"
              • "QUERY_STRING"
              • "HEADER"
              • "METHOD"
              • "BODY"
              • "SINGLE_QUERY_ARG"
              • "ALL_QUERY_ARGS"
            • Data — (String)

              When the value of Type is HEADER, enter the name of the header that you want AWS WAF to search, for example, User-Agent or Referer. The name of the header is not case sensitive.

              When the value of Type is SINGLE_QUERY_ARG, enter the name of the parameter that you want AWS WAF to search, for example, UserName or SalesRegion. The parameter name is not case sensitive.

              If the value of Type is any other value, omit Data.

          • TextTransformation — required — (String)

            Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass AWS WAF. If you specify a transformation, AWS WAF performs the transformation on RegexPatternSet before inspecting a request for a match.

            You can only specify a single type of TextTransformation.

            CMD_LINE

            When you're concerned that attackers are injecting an operating system commandline command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:

            • Delete the following characters: \ " ' ^

            • Delete spaces before the following characters: / (

            • Replace the following characters with a space: , ;

            • Replace multiple spaces with one space

            • Convert uppercase letters (A-Z) to lowercase (a-z)

            COMPRESS_WHITE_SPACE

            Use this option to replace the following characters with a space character (decimal 32):

            • \f, formfeed, decimal 12

            • \t, tab, decimal 9

            • \n, newline, decimal 10

            • \r, carriage return, decimal 13

            • \v, vertical tab, decimal 11

            • non-breaking space, decimal 160

            COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.

            HTML_ENTITY_DECODE

            Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:

            • Replaces (ampersand)quot; with "

            • Replaces (ampersand)nbsp; with a non-breaking space, decimal 160

            • Replaces (ampersand)lt; with a "less than" symbol

            • Replaces (ampersand)gt; with >

            • Replaces characters that are represented in hexadecimal format, (ampersand)#xhhhh;, with the corresponding characters

            • Replaces characters that are represented in decimal format, (ampersand)#nnnn;, with the corresponding characters

            LOWERCASE

            Use this option to convert uppercase letters (A-Z) to lowercase (a-z).

            URL_DECODE

            Use this option to decode a URL-encoded value.

            NONE

            Specify NONE if you don't want to perform any text transformations.

            Possible values include:
            • "NONE"
            • "COMPRESS_WHITE_SPACE"
            • "HTML_ENTITY_DECODE"
            • "LOWERCASE"
            • "CMD_LINE"
            • "URL_DECODE"
          • RegexPatternSetId — required — (String)

            The RegexPatternSetId for a RegexPatternSet. You use RegexPatternSetId to get information about a RegexPatternSet (see GetRegexPatternSet), update a RegexPatternSet (see UpdateRegexPatternSet), insert a RegexPatternSet into a RegexMatchSet or delete one from a RegexMatchSet (see UpdateRegexMatchSet), and delete an RegexPatternSet from AWS WAF (see DeleteRegexPatternSet).

            RegexPatternSetId is returned by CreateRegexPatternSet and by ListRegexPatternSets.

      • ChangeToken — (String)

        The ChangeToken that you used to submit the CreateRegexMatchSet request. You can also use this value to query the status of the request. For more information, see GetChangeTokenStatus.

createRule(params = {}, callback) ⇒ AWS.Request

Note: This is AWS WAF Classic documentation. For more information, see AWS WAF Classic in the developer guide. For the latest version of AWS WAF, use the AWS WAFV2 API and see the AWS WAF Developer Guide. With the latest version, AWS WAF has a single set of endpoints for regional and global use.

Creates a Rule, which contains the IPSet objects, ByteMatchSet objects, and other predicates that identify the requests that you want to block. If you add more than one predicate to a Rule, a request must match all of the specifications to be allowed or blocked. For example, suppose that you add the following to a Rule:

  • An IPSet that matches the IP address 192.0.2.44/32

  • A ByteMatchSet that matches BadBot in the User-Agent header

You then add the Rule to a WebACL and specify that you want to blocks requests that satisfy the Rule. For a request to be blocked, it must come from the IP address 192.0.2.44 and the User-Agent header in the request must contain the value BadBot.

To create and configure a Rule, perform the following steps:

  1. Create and update the predicates that you want to include in the Rule. For more information, see CreateByteMatchSet, CreateIPSet, and CreateSqlInjectionMatchSet.

  2. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of a CreateRule request.

  3. Submit a CreateRule request.

  4. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateRule request.

  5. Submit an UpdateRule request to specify the predicates that you want to include in the Rule.

  6. Create and update a WebACL that contains the Rule. For more information, see CreateWebACL.

It can't contain whitespace or metric names reserved for AWS WAF, including "All" and "Default_Action." You can't change MetricName after you create the Rule.

        • Predicates — required — (Array<map>)

          The Predicates object contains one Predicate element for each ByteMatchSet, IPSet, or SqlInjectionMatchSet object that you want to include in a Rule.

          • Negated — required — (Boolean)

            Set Negated to False if you want AWS WAF to allow, block, or count requests based on the settings in the specified ByteMatchSet, IPSet, SqlInjectionMatchSet, XssMatchSet, RegexMatchSet, GeoMatchSet, or SizeConstraintSet. For example, if an IPSet includes the IP address 192.0.2.44, AWS WAF will allow or block requests based on that IP address.

            Set Negated to True if you want AWS WAF to allow or block a request based on the negation of the settings in the ByteMatchSet, IPSet, SqlInjectionMatchSet, XssMatchSet, RegexMatchSet, GeoMatchSet, or SizeConstraintSet. For example, if an IPSet includes the IP address 192.0.2.44, AWS WAF will allow, block, or count requests based on all IP addresses except 192.0.2.44.

          • Type — required — (String)

            The type of predicate in a Rule, such as ByteMatch or IPSet.

createSizeConstraintSet(params = {}, callback) ⇒ AWS.Request

Note: This is AWS WAF Classic documentation. For more information, see AWS WAF Classic in the developer guide. For the latest version of AWS WAF, use the AWS WAFV2 API and see the AWS WAF Developer Guide. With the latest version, AWS WAF has a single set of endpoints for regional and global use.

Creates a SizeConstraintSet. You then use UpdateSizeConstraintSet to identify the part of a web request that you want AWS WAF to check for length, such as the length of the User-Agent header or the length of the query string. For example, you can create a SizeConstraintSet that matches any requests that have a query string that is longer than 100 bytes. You can then configure AWS WAF to reject those requests.

To create and configure a SizeConstraintSet, perform the following steps:

  1. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of a CreateSizeConstraintSet request.

  2. Submit a CreateSizeConstraintSet request.

  3. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateSizeConstraintSet request.

  4. Submit an UpdateSizeConstraintSet request to specify the part of the request that you want AWS WAF to inspect (for example, the header or the URI) and the value that you want AWS WAF to watch for.

    Context (this):

    • (AWS.Response) —

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error) —

      the error object returned from the request. Set to null if the request is successful.

    • data (Object) —

      the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

      • SizeConstraintSet — (map)

        A SizeConstraintSet that contains no SizeConstraint objects.

        • SizeConstraintSetId — required — (String)

          A unique identifier for a SizeConstraintSet. You use SizeConstraintSetId to get information about a SizeConstraintSet (see GetSizeConstraintSet), update a SizeConstraintSet (see UpdateSizeConstraintSet), insert a SizeConstraintSet into a Rule or delete one from a Rule (see UpdateRule), and delete a SizeConstraintSet from AWS WAF (see DeleteSizeConstraintSet).

          SizeConstraintSetId is returned by CreateSizeConstraintSet and by ListSizeConstraintSets.

        • Name — (String)

          The name, if any, of the SizeConstraintSet.

        • SizeConstraints — required — (Array<map>)

          Specifies the parts of web requests that you want to inspect the size of.

          • FieldToMatch — required — (map)

            Specifies where in a web request to look for the size constraint.

            • Type — required — (String)

              The part of the web request that you want AWS WAF to search for a specified string. Parts of a request that you can search include the following:

              • HEADER: A specified request header, for example, the value of the User-Agent or Referer header. If you choose HEADER for the type, specify the name of the header in Data.

              • METHOD: The HTTP method, which indicated the type of operation that the request is asking the origin to perform. Amazon CloudFront supports the following methods: DELETE, GET, HEAD, OPTIONS, PATCH, POST, and PUT.

              • QUERY_STRING: A query string, which is the part of a URL that appears after a ? character, if any.

              • URI: The part of a web request that identifies a resource, for example, /images/daily-ad.jpg.

              • BODY: The part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form. The request body immediately follows the request headers. Note that only the first 8192 bytes of the request body are forwarded to AWS WAF for inspection. To allow or block requests based on the length of the body, you can create a size constraint set. For more information, see CreateSizeConstraintSet.

              • SINGLE_QUERY_ARG: The parameter in the query string that you will inspect, such as UserName or SalesRegion. The maximum length for SINGLE_QUERY_ARG is 30 characters.

              • ALL_QUERY_ARGS: Similar to SINGLE_QUERY_ARG, but rather than inspecting a single parameter, AWS WAF will inspect all parameters within the query for the value or regex pattern that you specify in TargetString.

              Possible values include:
              • "URI"
              • "QUERY_STRING"
              • "HEADER"
              • "METHOD"
              • "BODY"
              • "SINGLE_QUERY_ARG"
              • "ALL_QUERY_ARGS"
            • Data — (String)

              When the value of Type is HEADER, enter the name of the header that you want AWS WAF to search, for example, User-Agent or Referer. The name of the header is not case sensitive.

              When the value of Type is SINGLE_QUERY_ARG, enter the name of the parameter that you want AWS WAF to search, for example, UserName or SalesRegion. The parameter name is not case sensitive.

              If the value of Type is any other value, omit Data.

          • TextTransformation — required — (String)

            Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass AWS WAF. If you specify a transformation, AWS WAF performs the transformation on FieldToMatch before inspecting it for a match.

            You can only specify a single type of TextTransformation.

            Note that if you choose BODY for the value of Type, you must choose NONE for TextTransformation because CloudFront forwards only the first 8192 bytes for inspection.

            NONE

            Specify NONE if you don't want to perform any text transformations.

            CMD_LINE

            When you're concerned that attackers are injecting an operating system command line command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:

            • Delete the following characters: \ " ' ^

            • Delete spaces before the following characters: / (

            • Replace the following characters with a space: , ;

            • Replace multiple spaces with one space

            • Convert uppercase letters (A-Z) to lowercase (a-z)

            COMPRESS_WHITE_SPACE

            Use this option to replace the following characters with a space character (decimal 32):

            • \f, formfeed, decimal 12

            • \t, tab, decimal 9

            • \n, newline, decimal 10

            • \r, carriage return, decimal 13

            • \v, vertical tab, decimal 11

            • non-breaking space, decimal 160

            COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.

            HTML_ENTITY_DECODE

            Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:

            • Replaces (ampersand)quot; with "

            • Replaces (ampersand)nbsp; with a non-breaking space, decimal 160

            • Replaces (ampersand)lt; with a "less than" symbol

            • Replaces (ampersand)gt; with >

            • Replaces characters that are represented in hexadecimal format, (ampersand)#xhhhh;, with the corresponding characters

            • Replaces characters that are represented in decimal format, (ampersand)#nnnn;, with the corresponding characters

            LOWERCASE

            Use this option to convert uppercase letters (A-Z) to lowercase (a-z).

            URL_DECODE

            Use this option to decode a URL-encoded value.

            Possible values include:
            • "NONE"
            • "COMPRESS_WHITE_SPACE"
            • "HTML_ENTITY_DECODE"
            • "LOWERCASE"
            • "CMD_LINE"
            • "URL_DECODE"
          • ComparisonOperator — required — (String)

            The type of comparison you want AWS WAF to perform. AWS WAF uses this in combination with the provided Size and FieldToMatch to build an expression in the form of "Size ComparisonOperator size in bytes of FieldToMatch". If that expression is true, the SizeConstraint is considered to match.

            EQ: Used to test if the Size is equal to the size of the FieldToMatch

            NE: Used to test if the Size is not equal to the size of the FieldToMatch

            LE: Used to test if the Size is less than or equal to the size of the FieldToMatch

            LT: Used to test if the Size is strictly less than the size of the FieldToMatch

            GE: Used to test if the Size is greater than or equal to the size of the FieldToMatch

            GT: Used to test if the Size is strictly greater than the size of the FieldToMatch

            Possible values include:
            • "EQ"
            • "NE"
            • "LE"
            • "LT"
            • "GE"
            • "GT"
          • Size — required — (Integer)

            The size in bytes that you want AWS WAF to compare against the size of the specified FieldToMatch. AWS WAF uses this in combination with ComparisonOperator and FieldToMatch to build an expression in the form of "Size ComparisonOperator size in bytes of FieldToMatch". If that expression is true, the SizeConstraint is considered to match.

            Valid values for size are 0 - 21474836480 bytes (0 - 20 GB).

            If you specify URI for the value of Type, the / in the URI counts as one character. For example, the URI /logo.jpg is nine characters long.

      • ChangeToken — (String)

        The ChangeToken that you used to submit the CreateSizeConstraintSet request. You can also use this value to query the status of the request. For more information, see GetChangeTokenStatus.

              When the value of Type is HEADER, enter the name of the header that you want AWS WAF to search, for example, User-Agent or Referer. The name of the header is not case sensitive.

              When the value of Type is SINGLE_QUERY_ARG, enter the name of the parameter that you want AWS WAF to search, for example, UserName or SalesRegion. The parameter name is not case sensitive.

              If the value of Type is any other value, omit Data.

          • TextTransformation — required — (String)

            Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass AWS WAF. If you specify a transformation, AWS WAF performs the transformation on FieldToMatch before inspecting it for a match.

            You can only specify a single type of TextTransformation.

            CMD_LINE

            When you're concerned that attackers are injecting an operating system command line command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:

            • Delete the following characters: \ " ' ^

            • Delete spaces before the following characters: / (

            • Replace the following characters with a space: , ;

            • Replace multiple spaces with one space

            • Convert uppercase letters (A-Z) to lowercase (a-z)

            COMPRESS_WHITE_SPACE

            Use this option to replace the following characters with a space character (decimal 32):

            • \f, formfeed, decimal 12

            • \t, tab, decimal 9

            • \n, newline, decimal 10

            • \r, carriage return, decimal 13

            • \v, vertical tab, decimal 11

            • non-breaking space, decimal 160

            COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.

            HTML_ENTITY_DECODE

            Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:

            • Replaces (ampersand)quot; with "

            • Replaces (ampersand)nbsp; with a non-breaking space, decimal 160

            • Replaces (ampersand)lt; with a "less than" symbol

            • Replaces (ampersand)gt; with >

            • Replaces characters that are represented in hexadecimal format, (ampersand)#xhhhh;, with the corresponding characters

            • Replaces characters that are represented in decimal format, (ampersand)#nnnn;, with the corresponding characters

            LOWERCASE

            Use this option to convert uppercase letters (A-Z) to lowercase (a-z).

            URL_DECODE

            Use this option to decode a URL-encoded value.

            NONE

            Specify NONE if you don't want to perform any text transformations.

            Possible values include:
            • "NONE"
            • "COMPRESS_WHITE_SPACE"
            • "HTML_ENTITY_DECODE"
            • "LOWERCASE"
            • "CMD_LINE"
            • "URL_DECODE"
      • ChangeToken — (String)

        The ChangeToken that you used to submit the CreateSqlInjectionMatchSet request. You can also use this value to query the status of the request. For more information, see GetChangeTokenStatus.

Returns:

  • (AWS.Request) —

    a handle to the operation request for subsequent event callback registration.

createWebACL(params = {}, callback) ⇒ AWS.Request

Note: This is AWS WAF Classic documentation. For more information, see AWS WAF Classic in the developer guide. For the latest version of AWS WAF, use the AWS WAFV2 API and see the AWS WAF Developer Guide. With the latest version, AWS WAF has a single set of endpoints for regional and global use.

Creates a WebACL, which contains the Rules that identify the CloudFront web requests that you want to allow, block, or count. AWS WAF evaluates Rules in order based on the value of Priority for each Rule.

You also specify a default action, either ALLOW or BLOCK. If a web request doesn't match any of the Rules in a WebACL, AWS WAF responds to the request with the default action.

To create and configure a WebACL, perform the following steps:

  1. Create and update the ByteMatchSet objects and other predicates that you want to include in Rules. For more information, see CreateByteMatchSet, UpdateByteMatchSet, CreateIPSet, UpdateIPSet, CreateSqlInjectionMatchSet, and UpdateSqlInjectionMatchSet.

  2. Create and update the Rules that you want to include in the WebACL. For more information, see CreateRule and UpdateRule.

  3. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of a CreateWebACL request.

  4. Submit a CreateWebACL request.

  5. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateWebACL request.

  6. Submit an UpdateWebACL request to specify the Rules that you want to include in the WebACL, to specify the default action, and to associate the WebACL with a CloudFront distribution.

For more information about how to use the AWS WAF API, see the AWS WAF Developer Guide.

            • ALLOW: AWS WAF allows requests

            • BLOCK: AWS WAF blocks requests

            • COUNT: AWS WAF increments a counter of the requests that match all of the conditions in the rule. AWS WAF then continues to inspect the web request based on the remaining rules in the web ACL. You can't specify COUNT for the default action for a WebACL.

            Possible values include:
            • "BLOCK"
            • "ALLOW"
            • "COUNT"
        • Rules — required — (Array<map>)

          An array that contains the action for each Rule in a WebACL, the priority of the Rule, and the ID of the Rule.

          • Priority — required — (Integer)

            Specifies the order in which the Rules in a WebACL are evaluated. Rules with a lower value for Priority are evaluated before Rules with a higher value. The value must be a unique integer. If you add multiple Rules to a WebACL, the values don't need to be consecutive.

          • RuleId — required — (String)

            The RuleId for a Rule. You use RuleId to get more information about a Rule (see GetRule), update a Rule (see UpdateRule), insert a Rule into a WebACL or delete a one from a WebACL (see UpdateWebACL), or delete a Rule from AWS WAF (see DeleteRule).

            RuleId is returned by CreateRule and by ListRules.

          • Action — (map)

            Specifies the action that CloudFront or AWS WAF takes when a web request matches the conditions in the Rule. Valid values for Action include the following:

            • ALLOW: CloudFront responds with the requested object.

            • BLOCK: CloudFront responds with an HTTP 403 (Forbidden) status code.

            • COUNT: AWS WAF increments a counter of requests that match the conditions in the rule and then continues to inspect the web request based on the remaining rules in the web ACL.

            ActivatedRule|OverrideAction applies only when updating or adding a RuleGroup to a WebACL. In this case, you do not use ActivatedRule|Action. For all other update requests, ActivatedRule|Action is used instead of ActivatedRule|OverrideAction.

            • Type — required — (String)

              Specifies how you want AWS WAF to respond to requests that match the settings in a Rule. Valid settings include the following:

              • ALLOW: AWS WAF allows requests

              • BLOCK: AWS WAF blocks requests

              • COUNT: AWS WAF increments a counter of the requests that match all of the conditions in the rule. AWS WAF then continues to inspect the web request based on the remaining rules in the web ACL. You can't specify COUNT for the default action for a WebACL.

              Possible values include:
              • "BLOCK"
              • "ALLOW"
              • "COUNT"
          • OverrideAction — (map)

            Use the OverrideAction to test your RuleGroup.

            Any rule in a RuleGroup can potentially block a request. If you set the OverrideAction to None, the RuleGroup will block a request if any individual rule in the RuleGroup matches the request and is configured to block that request. However if you first want to test the RuleGroup, set the OverrideAction to Count. The RuleGroup will then override any block action specified by individual rules contained within the group. Instead of blocking matching requests, those requests will be counted. You can view a record of counted requests using GetSampledRequests.

            ActivatedRule|OverrideAction applies only when updating or adding a RuleGroup to a WebACL. In this case you do not use ActivatedRule|Action. For all other update requests, ActivatedRule|Action is used instead of ActivatedRule|OverrideAction.

            • Type — required — (String)

              COUNT overrides the action specified by the individual rule within a RuleGroup . If set to NONE, the rule's action will take place.

              Possible values include:
              • "NONE"
              • "COUNT"
          • Type — (String)

            The rule type, either REGULAR, as defined by Rule, RATE_BASED, as defined by RateBasedRule, or GROUP, as defined by RuleGroup. The default is REGULAR. Although this field is optional, be aware that if you try to add a RATE_BASED rule to a web ACL without setting the type, the UpdateWebACL request will fail because the request tries to add a REGULAR rule with the specified ID, which does not exist.

            Possible values include:
            • "REGULAR"
            • "RATE_BASED"
            • "GROUP"
          • ExcludedRules — (Array<map>)

            An array of rules to exclude from a rule group. This is applicable only when the ActivatedRule refers to a RuleGroup.

            Sometimes it is necessary to troubleshoot rule groups that are blocking traffic unexpectedly (false positives). One troubleshooting technique is to identify the specific rule within the rule group that is blocking the legitimate traffic and then disable (exclude) that particular rule. You can exclude rules from both your own rule groups and AWS Marketplace rule groups that have been associated with a web ACL.

            Specifying ExcludedRules does not remove those rules from the rule group. Rather, it changes the action for the rules to COUNT. Therefore, requests that match an ExcludedRule are counted but not blocked. The RuleGroup owner will receive COUNT metrics for each ExcludedRule.

            If you want to exclude rules from a rule group that is already associated with a web ACL, perform the following steps:

            1. Use the AWS WAF logs to identify the IDs of the rules that you want to exclude. For more information about the logs, see Logging Web ACL Traffic Information.

            2. Submit an UpdateWebACL request that has two actions:

              • The first action deletes the existing rule group from the web ACL. That is, in the UpdateWebACL request, the first Updates:Action should be DELETE and Updates:ActivatedRule:RuleId should be the rule group that contains the rules that you want to exclude.

              • The second action inserts the same rule group back in, but specifying the rules to exclude. That is, the second Updates:Action should be INSERT, Updates:ActivatedRule:RuleId should be the rule group that you just removed, and ExcludedRules should contain the rules that you want to exclude.

            • RuleId — required — (String)

              The unique identifier for the rule to exclude from the rule group.

        • WebACLArn — (String)

          Tha Amazon Resource Name (ARN) of the web ACL.

      • ChangeToken — (String)

        The ChangeToken that you used to submit the CreateWebACL request. You can also use this value to query the status of the request. For more information, see GetChangeTokenStatus.

Returns:

  • (AWS.Request) —

    a handle to the operation request for subsequent event callback registration.

createWebACLMigrationStack(params = {}, callback) ⇒ AWS.Request

Creates an AWS CloudFormation WAFV2 template for the specified web ACL in the specified Amazon S3 bucket. Then, in CloudFormation, you create a stack from the template, to create the web ACL and its resources in AWS WAFV2. Use this to migrate your AWS WAF Classic web ACL to the latest version of AWS WAF.

This is part of a larger migration procedure for web ACLs from AWS WAF Classic to the latest version of AWS WAF. For the full procedure, including caveats and manual steps to complete the migration and switch over to the new web ACL, see Migrating your AWS WAF Classic resources to AWS WAF in the AWS WAF Developer Guide.

Service Reference:

Examples:

Calling the createWebACLMigrationStack operation

var params = {
  IgnoreUnsupportedType: true || false, /* required */
  S3BucketName: 'STRING_VALUE', /* required */
  WebACLId: 'STRING_VALUE' /* required */
};
wafregional.createWebACLMigrationStack(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {}) —
    • WebACLId — (String)

      The UUID of the WAF Classic web ACL that you want to migrate to WAF v2.

    • S3BucketName — (String)

      The name of the Amazon S3 bucket to store the CloudFormation template in. The S3 bucket must be configured as follows for the migration:

      • The bucket name must start with aws-waf-migration-. For example, aws-waf-migration-my-web-acl.

      • The bucket must be in the Region where you are deploying the template. For example, for a web ACL in us-west-2, you must use an Amazon S3 bucket in us-west-2 and you must deploy the template stack to us-west-2.

      • The bucket policies must permit the migration process to write data. For listings of the bucket policies, see the Examples section.

    • IgnoreUnsupportedType — (Boolean)

      Indicates whether to exclude entities that can't be migrated or to stop the migration. Set this to true to ignore unsupported entities in the web ACL during the migration. Otherwise, if AWS WAF encounters unsupported entities, it stops the process and throws an exception.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response) —

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error) —

      the error object returned from the request. Set to null if the request is successful.

    • data (Object) —

      the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

      • S3ObjectUrl — (String)

        The URL of the template created in Amazon S3.

Returns:

  • (AWS.Request) —

    a handle to the operation request for subsequent event callback registration.

createXssMatchSet(params = {}, callback) ⇒ AWS.Request

Note: This is AWS WAF Classic documentation. For more information, see AWS WAF Classic in the developer guide. For the latest version of AWS WAF, use the AWS WAFV2 API and see the AWS WAF Developer Guide. With the latest version, AWS WAF has a single set of endpoints for regional and global use.

Creates an XssMatchSet, which you use to allow, block, or count requests that contain cross-site scripting attacks in the specified part of web requests. AWS WAF searches for character sequences that are likely to be malicious strings.

To create and configure an XssMatchSet, perform the following steps:

  1. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of a CreateXssMatchSet request.

  2. Submit a CreateXssMatchSet request.

  3. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateXssMatchSet request.

  4. Submit an UpdateXssMatchSet request to specify the parts of web requests in which you want to allow, block, or count cross-site scripting attacks.

For more information about how to use the AWS WAF API to allow or block HTTP requests, see the AWS WAF Developer Guide.

              • URI: The part of a web request that identifies a resource, for example, /images/daily-ad.jpg.

              • BODY: The part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form. The request body immediately follows the request headers. Note that only the first 8192 bytes of the request body are forwarded to AWS WAF for inspection. To allow or block requests based on the length of the body, you can create a size constraint set. For more information, see CreateSizeConstraintSet.

              • SINGLE_QUERY_ARG: The parameter in the query string that you will inspect, such as UserName or SalesRegion. The maximum length for SINGLE_QUERY_ARG is 30 characters.

              • ALL_QUERY_ARGS: Similar to SINGLE_QUERY_ARG, but rather than inspecting a single parameter, AWS WAF will inspect all parameters within the query for the value or regex pattern that you specify in TargetString.

              Possible values include:
              • "URI"
              • "QUERY_STRING"
              • "HEADER"
              • "METHOD"
              • "BODY"
              • "SINGLE_QUERY_ARG"
              • "ALL_QUERY_ARGS"
            • Data — (String)

              When the value of Type is HEADER, enter the name of the header that you want AWS WAF to search, for example, User-Agent or Referer. The name of the header is not case sensitive.

              When the value of Type is SINGLE_QUERY_ARG, enter the name of the parameter that you want AWS WAF to search, for example, UserName or SalesRegion. The parameter name is not case sensitive.

              If the value of Type is any other value, omit Data.

          • TextTransformation — required — (String)

            Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass AWS WAF. If you specify a transformation, AWS WAF performs the transformation on FieldToMatch before inspecting it for a match.

            You can only specify a single type of TextTransformation.

            CMD_LINE

            When you're concerned that attackers are injecting an operating system command line command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:

            • Delete the following characters: \ " ' ^

            • Delete spaces before the following characters: / (

            • Replace the following characters with a space: , ;

            • Replace multiple spaces with one space

            • Convert uppercase letters (A-Z) to lowercase (a-z)

            COMPRESS_WHITE_SPACE

            Use this option to replace the following characters with a space character (decimal 32):

            • \f, formfeed, decimal 12

            • \t, tab, decimal 9

            • \n, newline, decimal 10

            • \r, carriage return, decimal 13

            • \v, vertical tab, decimal 11

            • non-breaking space, decimal 160

            COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.

            HTML_ENTITY_DECODE

            Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:

            • Replaces (ampersand)quot; with "

            • Replaces (ampersand)nbsp; with a non-breaking space, decimal 160

            • Replaces (ampersand)lt; with a "less than" symbol

            • Replaces (ampersand)gt; with >

            • Replaces characters that are represented in hexadecimal format, (ampersand)#xhhhh;, with the corresponding characters

            • Replaces characters that are represented in decimal format, (ampersand)#nnnn;, with the corresponding characters

            LOWERCASE

            Use this option to convert uppercase letters (A-Z) to lowercase (a-z).

            URL_DECODE

            Use this option to decode a URL-encoded value.

            NONE

            Specify NONE if you don't want to perform any text transformations.

            Possible values include:
            • "NONE"
            • "COMPRESS_WHITE_SPACE"
            • "HTML_ENTITY_DECODE"
            • "LOWERCASE"
            • "CMD_LINE"
            • "URL_DECODE"
      • ChangeToken — (String)

        The ChangeToken that you used to submit the CreateXssMatchSet request. You can also use this value to query the status of the request. For more information, see GetChangeTokenStatus.

Returns:

  • (AWS.Request) —

    a handle to the operation request for subsequent event callback registration.

      the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

      • ByteMatchSet — (map)

        Information about the ByteMatchSet that you specified in the GetByteMatchSet request. For more information, see the following topics:

        • ByteMatchSet: Contains ByteMatchSetId, ByteMatchTuples, and Name

        • ByteMatchTuples: Contains an array of ByteMatchTuple objects. Each ByteMatchTuple object contains FieldToMatch, PositionalConstraint, TargetString, and TextTransformation

        • FieldToMatch: Contains Data and Type

        • ByteMatchSetId — required — (String)

          The ByteMatchSetId for a ByteMatchSet. You use ByteMatchSetId to get information about a ByteMatchSet (see GetByteMatchSet), update a ByteMatchSet (see UpdateByteMatchSet), insert a ByteMatchSet into a Rule or delete one from a Rule (see UpdateRule), and delete a ByteMatchSet from AWS WAF (see DeleteByteMatchSet).

          ByteMatchSetId is returned by CreateByteMatchSet and by ListByteMatchSets.

        • Name — (String)

          A friendly name or description of the ByteMatchSet. You can't change Name after you create a ByteMatchSet.

        • ByteMatchTuples — required — (Array<map>)

          Specifies the bytes (typically a string that corresponds with ASCII characters) that you want AWS WAF to search for in web requests, the location in requests that you want AWS WAF to search, and other settings.

          • FieldToMatch — required — (map)

            The part of a web request that you want AWS WAF to search, such as a specified header or a query string. For more information, see FieldToMatch.

            • Type — required — (String)

              The part of the web request that you want AWS WAF to search for a specified string. Parts of a request that you can search include the following:

              • HEADER: A specified request header, for example, the value of the User-Agent or Referer header. If you choose HEADER for the type, specify the name of the header in Data.

              • METHOD: The HTTP method, which indicated the type of operation that the request is asking the origin to perform. Amazon CloudFront supports the following methods: DELETE, GET, HEAD, OPTIONS, PATCH, POST, and PUT.

              • QUERY_STRING: A query string, which is the part of a URL that appears after a ? character, if any.

              • URI: The part of a web request that identifies a resource, for example, /images/daily-ad.jpg.

              • BODY: The part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form. The request body immediately follows the request headers. Note that only the first 8192 bytes of the request body are forwarded to AWS WAF for inspection. To allow or block requests based on the length of the body, you can create a size constraint set. For more information, see CreateSizeConstraintSet.

              • SINGLE_QUERY_ARG: The parameter in the query string that you will inspect, such as UserName or SalesRegion. The maximum length for SINGLE_QUERY_ARG is 30 characters.

              • ALL_QUERY_ARGS: Similar to SINGLE_QUERY_ARG, but rather than inspecting a single parameter, AWS WAF will inspect all parameters within the query for the value or regex pattern that you specify in TargetString.

              Possible values include:
              • "URI"
              • "QUERY_STRING"
              • "HEADER"
              • "METHOD"
              • "BODY"
              • "SINGLE_QUERY_ARG"
              • "ALL_QUERY_ARGS"
            • Data — (String)

              When the value of Type is HEADER, enter the name of the header that you want AWS WAF to search, for example, User-Agent or Referer. The name of the header is not case sensitive.

              When the value of Type is SINGLE_QUERY_ARG, enter the name of the parameter that you want AWS WAF to search, for example, UserName or SalesRegion. The parameter name is not case sensitive.

              If the value of Type is any other value, omit Data.

          • TargetString — required — (Buffer, Typed Array, Blob, String)

            The value that you want AWS WAF to search for. AWS WAF searches for the specified string in the part of web requests that you specified in FieldToMatch. The maximum length of the value is 50 bytes.

            Valid values depend on the values that you specified for FieldToMatch:

            • HEADER: The value that you want AWS WAF to search for in the request header that you specified in FieldToMatch, for example, the value of the User-Agent or Referer header.

            • METHOD: The HTTP method, which indicates the type of operation specified in the request. CloudFront supports the following methods: DELETE, GET, HEAD, OPTIONS, PATCH, POST, and PUT.

            • QUERY_STRING: The value that you want AWS WAF to search for in the query string, which is the part of a URL that appears after a ? character.

            • URI: The value that you want AWS WAF to search for in the part of a URL that identifies a resource, for example, /images/daily-ad.jpg.

            • BODY: The part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form. The request body immediately follows the request headers. Note that only the first 8192 bytes of the request body are forwarded to AWS WAF for inspection. To allow or block requests based on the length of the body, you can create a size constraint set. For more information, see CreateSizeConstraintSet.

            • SINGLE_QUERY_ARG: The parameter in the query string that you will inspect, such as UserName or SalesRegion. The maximum length for SINGLE_QUERY_ARG is 30 characters.

            • ALL_QUERY_ARGS: Similar to SINGLE_QUERY_ARG, but instead of inspecting a single parameter, AWS WAF inspects all parameters within the query string for the value or regex pattern that you specify in TargetString.

            If TargetString includes alphabetic characters A-Z and a-z, note that the value is case sensitive.

            If you're using the AWS WAF API

            Specify a base64-encoded version of the value. The maximum length of the value before you base64-encode it is 50 bytes.

            For example, suppose the value of Type is HEADER and the value of Data is User-Agent. If you want to search the User-Agent header for the value BadBot, you base64-encode BadBot using MIME base64-encoding and include the resulting value, QmFkQm90, in the value of TargetString.

            If you're using the AWS CLI or one of the AWS SDKs

            The value that you want AWS WAF to search for. The SDK automatically base64 encodes the value.

          • TextTransformation — required — (String)

            Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass AWS WAF. If you specify a transformation, AWS WAF performs the transformation on FieldToMatch before inspecting it for a match.

            You can only specify a single type of TextTransformation.

            CMD_LINE

            When you're concerned that attackers are injecting an operating system command line command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:

            • Delete the following characters: \ " ' ^

            • Delete spaces before the following characters: / (

            • Replace the following characters with a space: , ;

            • Replace multiple spaces with one space

            • Convert uppercase letters (A-Z) to lowercase (a-z)

getChangeToken(params = {}, callback) ⇒ AWS.Request

Note: This is AWS WAF Classic documentation. For more information, see AWS WAF Classic in the developer guide. For the latest version of AWS WAF, use the AWS WAFV2 API and see the AWS WAF Developer Guide. With the latest version, AWS WAF has a single set of endpoints for regional and global use.

When you want to create, update, or delete AWS WAF objects, get a change token and include the change token in the create, update, or delete request. Change tokens ensure that your application doesn't submit conflicting requests to AWS WAF.

Each create, update, or delete request must use a unique change token. If your application submits a GetChangeToken request and then submits a second GetChangeToken request before submitting a create, update, or delete request, the second GetChangeToken request returns the same value as the first GetChangeToken request.

When you use a change token in a create, update, or delete request, the status of the change token changes to PENDING, which indicates that AWS WAF is propagating the change to all AWS WAF servers. Use GetChangeTokenStatus to determine the status of your change token.

Service Reference:

Examples:

To get a change token


/* The following example returns a change token to use for a create, update or delete operation. */

 var params = {
 };
 wafregional.getChangeToken(params, function(err, data) {
   if (err) console.log(err, err.stack); // an error occurred
   else     console.log(data);           // successful response
   /*
   data = {
    ChangeToken: "abcd12f2-46da-4fdb-b8d5-fbd4c466928f"
   }
   */
 });

Calling the getChangeToken operation

var params = {
};
wafregional.getChangeToken(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {})

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response) —

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error) —

      the error object returned from the request. Set to null if the request is successful.

    • data (Object) —

      the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

      • ChangeToken — (String)

        The ChangeToken that you used in the request. Use this value in a GetChangeTokenStatus request to get the current status of the request.

Returns:

  • (AWS.Request) —

    a handle to the operation request for subsequent event callback registration.

getChangeTokenStatus(params = {}, callback) ⇒ AWS.Request

Note: This is AWS WAF Classic documentation. For more information, see AWS WAF Classic in the developer guide. For the latest version of AWS WAF, use the AWS WAFV2 API and see the AWS WAF Developer Guide. With the latest version, AWS WAF has a single set of endpoints for regional and global use.

Returns the status of a ChangeToken that you got by calling GetChangeToken. ChangeTokenStatus is one of the following values:

  • PROVISIONED: You requested the change token by calling GetChangeToken, but you haven't used it yet in a call to create, update, or delete an AWS WAF object.

  • PENDING: AWS WAF is propagating the create, update, or delete request to all AWS WAF servers.

  • INSYNC: Propagation is complete.

Note: This is AWS WAF Classic documentation. For more information, see AWS WAF Classic in the developer guide. For the latest version of AWS WAF, use the AWS WAFV2 API and see the AWS WAF Developer Guide. With the latest version, AWS WAF has a single set of endpoints for regional and global use.

Gets detailed information about a specified number of requests--a sample--that AWS WAF randomly selects from among the first 5,000 requests that your AWS resource received during a time range that you choose. You can specify a sample size of up to 500 requests, and you can specify any time range in the previous three hours.

GetSampledRequests returns a time range, which is usually the time range that you specified. However, if your resource (such as a CloudFront distribution) received 5,000 requests before the specified time range elapsed, GetSampledRequests returns an updated time range. This new time range indicates the actual period during which AWS WAF selected the requests in the sample.

        • SizeConstraintSetId — required — (String)

          A unique identifier for a SizeConstraintSet. You use SizeConstraintSetId to get information about a SizeConstraintSet (see GetSizeConstraintSet), update a SizeConstraintSet (see UpdateSizeConstraintSet), insert a SizeConstraintSet into a Rule or delete one from a Rule (see UpdateRule), and delete a SizeConstraintSet from AWS WAF (see DeleteSizeConstraintSet).

          SizeConstraintSetId is returned by CreateSizeConstraintSet and by ListSizeConstraintSets.

        • Name — (String)

          The name, if any, of the SizeConstraintSet.

        • SizeConstraints — required — (Array<map>)

          Specifies the parts of web requests that you want to inspect the size of.

          • FieldToMatch — required — (map)

            Specifies where in a web request to look for the size constraint.

            • Type — required — (String)

              The part of the web request that you want AWS WAF to search for a specified string. Parts of a request that you can search include the following:

              • HEADER: A specified request header, for example, the value of the User-Agent or Referer header. If you choose HEADER for the type, specify the name of the header in Data.

              • METHOD: The HTTP method, which indicated the type of operation that the request is asking the origin to perform. Amazon CloudFront supports the following methods: DELETE, GET, HEAD, OPTIONS, PATCH, POST, and PUT.

              • QUERY_STRING: A query string, which is the part of a URL that appears after a ? character, if any.

              • URI: The part of a web request that identifies a resource, for example, /images/daily-ad.jpg.

              • BODY: The part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form. The request body immediately follows the request headers. Note that only the first 8192 bytes of the request body are forwarded to AWS WAF for inspection. To allow or block requests based on the length of the body, you can create a size constraint set. For more information, see CreateSizeConstraintSet.

              • SINGLE_QUERY_ARG: The parameter in the query string that you will inspect, such as UserName or SalesRegion. The maximum length for SINGLE_QUERY_ARG is 30 characters.

              • ALL_QUERY_ARGS: Similar to SINGLE_QUERY_ARG, but rather than inspecting a single parameter, AWS WAF will inspect all parameters within the query for the value or regex pattern that you specify in TargetString.

              Possible values include:
              • "URI"
              • "QUERY_STRING"
              • "HEADER"
              • "METHOD"
              • "BODY"
              • "SINGLE_QUERY_ARG"
              • "ALL_QUERY_ARGS"
            • Data — (String)

              When the value of Type is HEADER, enter the name of the header that you want AWS WAF to search, for example, User-Agent or Referer. The name of the header is not case sensitive.

              When the value of Type is SINGLE_QUERY_ARG, enter the name of the parameter that you want AWS WAF to search, for example, UserName or SalesRegion. The parameter name is not case sensitive.

              If the value of Type is any other value, omit Data.

          • TextTransformation — required — (String)

            Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass AWS WAF. If you specify a transformation, AWS WAF performs the transformation on FieldToMatch before inspecting it for a match.

            You can only specify a single type of TextTransformation.

            Note that if you choose BODY for the value of Type, you must choose NONE for TextTransformation because CloudFront forwards only the first 8192 bytes for inspection.

            NONE

            Specify NONE if you don't want to perform any text transformations.

            CMD_LINE

            When you're concerned that attackers are injecting an operating system command line command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:

            • Delete the following characters: \ " ' ^

            • Delete spaces before the following characters: / (

            • Replace the following characters with a space: , ;

            • Replace multiple spaces with one space

            • Convert uppercase letters (A-Z) to lowercase (a-z)

            COMPRESS_WHITE_SPACE

            Use this option to replace the following characters with a space character (decimal 32):

            • \f, formfeed, decimal 12

            • \t, tab, decimal 9

            • \n, newline, decimal 10

            • \r, carriage return, decimal 13

            • \v, vertical tab, decimal 11

            • non-breaking space, decimal 160

            COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.

            HTML_ENTITY_DECODE

            Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:

            • Replaces (ampersand)quot; with "

            • Replaces (ampersand)nbsp; with a non-breaking space, decimal 160

            • Replaces (ampersand)lt; with a "less than" symbol

            • Replaces (ampersand)gt; with >

            • Replaces characters that are represented in hexadecimal format, (ampersand)#xhhhh;, with the corresponding characters

            • Replaces characters that are represented in decimal format, (ampersand)#nnnn;, with the corresponding characters

            LOWERCASE

            Use this option to convert uppercase letters (A-Z) to lowercase (a-z).

            URL_DECODE

            Use this option to decode a URL-encoded value.

            Possible values include:
            • "NONE"
            • "COMPRESS_WHITE_SPACE"
            • "HTML_ENTITY_DECODE"
            • "LOWERCASE"
            • "CMD_LINE"
            • "URL_DECODE"
          • ComparisonOperator — required — (String)

            The type of comparison you want AWS WAF to perform. AWS WAF uses this in combination with the provided Size and FieldToMatch to build an expression in the form of "Size ComparisonOperator size in bytes of FieldToMatch". If that expression is true, the SizeConstraint is considered to match.

            EQ: Used to test if the Size is equal to the size of the FieldToMatch

            NE: Used to test if the Size is not equal to the size of the FieldToMatch

            LE: Used to test if the Size is less than or equal to the size of the FieldToMatch

            LT: Used to test if the Size is strictly less than the size of the FieldToMatch

            GE: Used to test if the Size is greater than or equal to the size of the FieldToMatch

            GT: Used to test if the Size is strictly greater than the size of the FieldToMatch

            Possible values include:
            • "EQ"
            • "NE"
            • "LE"
            • "LT"
            • "GE"
            • "GT"
          • Size — required — (Integer)

            The size in bytes that you want AWS WAF to compare against the size of the specified FieldToMatch. AWS WAF uses this in combination with ComparisonOperator and FieldToMatch to build an expression in the form of "Size ComparisonOperator size in bytes of FieldToMatch". If that expression is true, the SizeConstraint is considered to match.

            Valid values for size are 0 - 21474836480 bytes (0 - 20 GB).

            If you specify URI for the value of Type, the / in the URI counts as one character. For example, the URI /logo.jpg is nine characters long.

Returns:

  • (AWS.Request) —

    a handle to the operation request for subsequent event callback registration.

          WebACLId is returned by CreateWebACL and by ListWebACLs.

        • Name — (String)

          A friendly name or description of the WebACL. You can't change the name of a WebACL after you create it.

        • MetricName — (String)

          A friendly name or description for the metrics for this WebACL. The name can contain only alphanumeric characters (A-Z, a-z, 0-9), with maximum length 128 and minimum length one. It can't contain whitespace or metric names reserved for AWS WAF, including "All" and "Default_Action." You can't change MetricName after you create the WebACL.

        • DefaultAction — required — (map)

          The action to perform if none of the Rules contained in the WebACL match. The action is specified by the WafAction object.

          • Type — required — (String)

            Specifies how you want AWS WAF to respond to requests that match the settings in a Rule. Valid settings include the following:

            • ALLOW: AWS WAF allows requests

            • BLOCK: AWS WAF blocks requests

            • COUNT: AWS WAF increments a counter of the requests that match all of the conditions in the rule. AWS WAF then continues to inspect the web request based on the remaining rules in the web ACL. You can't specify COUNT for the default action for a WebACL.

            Possible values include:
            • "BLOCK"
            • "ALLOW"
            • "COUNT"
        • Rules — required — (Array<map>)

          An array that contains the action for each Rule in a WebACL, the priority of the Rule, and the ID of the Rule.

          • Priority — required — (Integer)

            Specifies the order in which the Rules in a WebACL are evaluated. Rules with a lower value for Priority are evaluated before Rules with a higher value. The value must be a unique integer. If you add multiple Rules to a WebACL, the values don't need to be consecutive.

          • RuleId — required — (String)

            The RuleId for a Rule. You use RuleId to get more information about a Rule (see GetRule), update a Rule (see UpdateRule), insert a Rule into a WebACL or delete a one from a WebACL (see UpdateWebACL), or delete a Rule from AWS WAF (see DeleteRule).

            RuleId is returned by CreateRule and by ListRules.

          • Action — (map)

            Specifies the action that CloudFront or AWS WAF takes when a web request matches the conditions in the Rule. Valid values for Action include the following:

            • ALLOW: CloudFront responds with the requested object.

            • BLOCK: CloudFront responds with an HTTP 403 (Forbidden) status code.

            • COUNT: AWS WAF increments a counter of requests that match the conditions in the rule and then continues to inspect the web request based on the remaining rules in the web ACL.

            ActivatedRule|OverrideAction applies only when updating or adding a RuleGroup to a WebACL. In this case, you do not use ActivatedRule|Action. For all other update requests, ActivatedRule|Action is used instead of ActivatedRule|OverrideAction.

            • Type — required — (String)

              Specifies how you want AWS WAF to respond to requests that match the settings in a Rule. Valid settings include the following:

              • ALLOW: AWS WAF allows requests

              • BLOCK: AWS WAF blocks requests

              • COUNT: AWS WAF increments a counter of the requests that match all of the conditions in the rule. AWS WAF then continues to inspect the web request based on the remaining rules in the web ACL. You can't specify COUNT for the default action for a WebACL.

              Possible values include:
              • "BLOCK"
              • "ALLOW"
              • "COUNT"
          • OverrideAction — (map)

            Use the OverrideAction to test your RuleGroup.

            Any rule in a RuleGroup can potentially block a request. If you set the OverrideAction to None, the RuleGroup will block a request if any individual rule in the RuleGroup matches the request and is configured to block that request. However if you first want to test the RuleGroup, set the OverrideAction to Count. The RuleGroup will then override any block action specified by individual rules contained within the group. Instead of blocking matching requests, those requests will be counted. You can view a record of counted requests using GetSampledRequests.

            ActivatedRule|OverrideAction applies only when updating or adding a RuleGroup to a WebACL. In this case you do not use ActivatedRule|Action. For all other update requests, ActivatedRule|Action is used instead of ActivatedRule|OverrideAction.

            • Type — required — (String)

              COUNT overrides the action specified by the individual rule within a RuleGroup . If set to NONE, the rule's action will take place.

              Possible values include:
              • "NONE"
              • "COUNT"
          • Type — (String)

            The rule type, either REGULAR, as defined by Rule, RATE_BASED, as defined by RateBasedRule, or GROUP, as defined by RuleGroup. The default is REGULAR. Although this field is optional, be aware that if you try to add a RATE_BASED rule to a web ACL without setting the type, the UpdateWebACL request will fail because the request tries to add a REGULAR rule with the specified ID, which does not exist.

            Possible values include:
            • "REGULAR"
            • "RATE_BASED"
            • "GROUP"
          • ExcludedRules — (Array<map>)

            An array of rules to exclude from a rule group. This is applicable only when the ActivatedRule refers to a RuleGroup.

            Sometimes it is necessary to troubleshoot rule groups that are blocking traffic unexpectedly (false positives). One troubleshooting technique is to identify the specific rule within the rule group that is blocking the legitimate traffic and then disable (exclude) that particular rule. You can exclude rules from both your own rule groups and AWS Marketplace rule groups that have been associated with a web ACL.

            Specifying ExcludedRules does not remove those rules from the rule group. Rather, it changes the action for the rules to COUNT. Therefore, requests that match an ExcludedRule are counted but not blocked. The RuleGroup owner will receive COUNT metrics for each ExcludedRule.

            If you want to exclude rules from a rule group that is already associated with a web ACL, perform the following steps:

            1. Use the AWS WAF logs to identify the IDs of the rules that you want to exclude. For more information about the logs, see Logging Web ACL Traffic Information.

            2. Submit an UpdateWebACL request that has two actions:

              • The first action deletes the existing rule group from the web ACL. That is, in the UpdateWebACL request, the first Updates:Action should be DELETE and Updates:ActivatedRule:RuleId should be the rule group that contains the rules that you want to exclude.

              • The second action inserts the same rule group back in, but specifying the rules to exclude. That is, the second Updates:Action should be INSERT, Updates:ActivatedRule:RuleId should be the rule group that you just removed, and ExcludedRules should contain the rules that you want to exclude.

            • RuleId — required — (String)

              The unique identifier for the rule to exclude from the rule group.

        • WebACLArn — (String)

          Tha Amazon Resource Name (ARN) of the web ACL.

Returns:

  • (AWS.Request) —

    a handle to the operation request for subsequent event callback registration.

        • FieldToMatch: Contains Data and Type

        • XssMatchSetId — required — (String)

          A unique identifier for an XssMatchSet. You use XssMatchSetId to get information about an XssMatchSet (see GetXssMatchSet), update an XssMatchSet (see UpdateXssMatchSet), insert an XssMatchSet into a Rule or delete one from a Rule (see UpdateRule), and delete an XssMatchSet from AWS WAF (see DeleteXssMatchSet).

          XssMatchSetId is returned by CreateXssMatchSet and by ListXssMatchSets.

        • Name — (String)

          The name, if any, of the XssMatchSet.

        • XssMatchTuples — required — (Array<map>)

          Specifies the parts of web requests that you want to inspect for cross-site scripting attacks.

          • FieldToMatch — required — (map)

            Specifies where in a web request to look for cross-site scripting attacks.

            • Type — required — (String)

              The part of the web request that you want AWS WAF to search for a specified string. Parts of a request that you can search include the following:

              • HEADER: A specified request header, for example, the value of the User-Agent or Referer header. If you choose HEADER for the type, specify the name of the header in Data.

              • METHOD: The HTTP method, which indicated the type of operation that the request is asking the origin to perform. Amazon CloudFront supports the following methods: DELETE, GET, HEAD, OPTIONS, PATCH, POST, and PUT.

              • QUERY_STRING: A query string, which is the part of a URL that appears after a ? character, if any.

              • URI: The part of a web request that identifies a resource, for example, /images/daily-ad.jpg.

              • BODY: The part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form. The request body immediately follows the request headers. Note that only the first 8192 bytes of the request body are forwarded to AWS WAF for inspection. To allow or block requests based on the length of the body, you can create a size constraint set. For more information, see CreateSizeConstraintSet.

              • SINGLE_QUERY_ARG: The parameter in the query string that you will inspect, such as UserName or SalesRegion. The maximum length for SINGLE_QUERY_ARG is 30 characters.

              • ALL_QUERY_ARGS: Similar to SINGLE_QUERY_ARG, but rather than inspecting a single parameter, AWS WAF will inspect all parameters within the query for the value or regex pattern that you specify in TargetString.

              Possible values include:
              • "URI"
              • "QUERY_STRING"
              • "HEADER"
              • "METHOD"
              • "BODY"
              • "SINGLE_QUERY_ARG"
              • "ALL_QUERY_ARGS"
            • Data — (String)

              When the value of Type is HEADER, enter the name of the header that you want AWS WAF to search, for example, User-Agent or Referer. The name of the header is not case sensitive.

              When the value of Type is SINGLE_QUERY_ARG, enter the name of the parameter that you want AWS WAF to search, for example, UserName or SalesRegion. The parameter name is not case sensitive.

              If the value of Type is any other value, omit Data.

          • TextTransformation — required — (String)

            Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass AWS WAF. If you specify a transformation, AWS WAF performs the transformation on FieldToMatch before inspecting it for a match.

            You can only specify a single type of TextTransformation.

            CMD_LINE

            When you're concerned that attackers are injecting an operating system command line command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:

            • Delete the following characters: \ " ' ^

            • Delete spaces before the following characters: / (

            • Replace the following characters with a space: , ;

            • Replace multiple spaces with one space

            • Convert uppercase letters (A-Z) to lowercase (a-z)

            COMPRESS_WHITE_SPACE

            Use this option to replace the following characters with a space character (decimal 32):

            • \f, formfeed, decimal 12

            • \t, tab, decimal 9

            • \n, newline, decimal 10

            • \r, carriage return, decimal 13

            • \v, vertical tab, decimal 11

            • non-breaking space, decimal 160

            COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.

            HTML_ENTITY_DECODE

            Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:

            • Replaces (ampersand)quot; with "

            • Replaces (ampersand)nbsp; with a non-breaking space, decimal 160

            • Replaces (ampersand)lt; with a "less than" symbol

            • Replaces (ampersand)gt; with >

            • Replaces characters that are represented in hexadecimal format, (ampersand)#xhhhh;, with the corresponding characters

            • Replaces characters that are represented in decimal format, (ampersand)#nnnn;, with the corresponding characters

            LOWERCASE

            Use this option to convert uppercase letters (A-Z) to lowercase (a-z).

            URL_DECODE

            Use this option to decode a URL-encoded value.

            NONE

            Specify NONE if you don't want to perform any text transformations.

            Possible values include:
            • "NONE"
            • "COMPRESS_WHITE_SPACE"
            • "HTML_ENTITY_DECODE"
            • "LOWERCASE"
            • "CMD_LINE"
            • "URL_DECODE"

Returns:

  • (AWS.Request) —

    a handle to the operation request for subsequent event callback registration.

Returns an array of ActivatedRule objects.

Service Reference:

Examples:

Calling the listActivatedRulesInRuleGroup operation

var params = {
  Limit: 'NUMBER_VALUE',
  NextMarker: 'STRING_VALUE',
  RuleGroupId: 'STRING_VALUE'
};
wafregional.listActivatedRulesInRuleGroup(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {}) —
    • RuleGroupId — (String)

      The RuleGroupId of the RuleGroup for which you want to get a list of ActivatedRule objects.

    • NextMarker — (String)

      If you specify a value for Limit and you have more ActivatedRules than the value of Limit, AWS WAF returns a NextMarker value in the response that allows you to list another group of ActivatedRules. For the second and subsequent ListActivatedRulesInRuleGroup requests, specify the value of NextMarker from the previous response to get information about another batch of ActivatedRules.

    • Limit — (Integer)

      Specifies the number of ActivatedRules that you want AWS WAF to return for this request. If you have more ActivatedRules than the number that you specify for Limit, the response includes a NextMarker value that you can use to get another batch of ActivatedRules.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response) —

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error) —

      the error object returned from the request. Set to null if the request is successful.

    • data (Object) —

      the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

      • NextMarker — (String)

        If you have more ActivatedRules than the number that you specified for Limit in the request, the response includes a NextMarker value. To list more ActivatedRules, submit another ListActivatedRulesInRuleGroup request, and specify the NextMarker value from the response in the NextMarker value in the next request.

      • ActivatedRules — (Array<map>)

        An array of ActivatedRules objects.

        • Priority — required — (Integer)

          Specifies the order in which the Rules in a WebACL are evaluated. Rules with a lower value for Priority are evaluated before Rules with a higher value. The value must be a unique integer. If you add multiple Rules to a WebACL, the values don't need to be consecutive.

        • RuleId — required — (String)

          The RuleId for a Rule. You use RuleId to get more information about a Rule (see GetRule), update a Rule (see UpdateRule), insert a Rule into a WebACL or delete a one from a WebACL (see UpdateWebACL), or delete a Rule from AWS WAF (see DeleteRule).

          RuleId is returned by CreateRule and by ListRules.

        • Action — (map)

          Specifies the action that CloudFront or AWS WAF takes when a web request matches the conditions in the Rule. Valid values for Action include the following:

          • ALLOW: CloudFront responds with the requested object.

          • BLOCK: CloudFront responds with an HTTP 403 (Forbidden) status code.

          • COUNT: AWS WAF increments a counter of requests that match the conditions in the rule and then continues to inspect the web request based on the remaining rules in the web ACL.

          ActivatedRule|OverrideAction applies only when updating or adding a RuleGroup to a WebACL. In this case, you do not use ActivatedRule|Action. For all other update requests, ActivatedRule|Action is used instead of ActivatedRule|OverrideAction.

          • Type — required — (String)

            Specifies how you want AWS WAF to respond to requests that match the settings in a Rule. Valid settings include the following:

            • ALLOW: AWS WAF allows requests

            • BLOCK: AWS WAF blocks requests

            • COUNT: AWS WAF increments a counter of the requests that match all of the conditions in the rule. AWS WAF then continues to inspect the web request based on the remaining rules in the web ACL. You can't specify COUNT for the default action for a WebACL.

            Possible values include:
            • "BLOCK"
            • "ALLOW"
            • "COUNT"
        • OverrideAction — (map)

          Use the OverrideAction to test your RuleGroup.

          Any rule in a RuleGroup can potentially block a request. If you set the OverrideAction to None, the RuleGroup will block a request if any individual rule in the RuleGroup matches the request and is configured to block that request. However if you first want to test the RuleGroup, set the OverrideAction to Count. The RuleGroup will then override any block action specified by individual rules contained within the group. Instead of blocking matching requests, those requests will be counted. You can view a record of counted requests using GetSampledRequests.

          ActivatedRule|OverrideAction applies only when updating or adding a RuleGroup to a WebACL. In this case you do not use ActivatedRule|Action. For all other update requests, ActivatedRule|Action is used instead of ActivatedRule|OverrideAction.

          • Type — required — (String)

            COUNT overrides the action specified by the individual rule within a RuleGroup . If set to NONE, the rule's action will take place.

            Possible values include:
            • "NONE"
            • "COUNT"
        • Type — (String)

          The rule type, either REGULAR, as defined by Rule, RATE_BASED, as defined by RateBasedRule, or GROUP, as defined by RuleGroup. The default is REGULAR. Although this field is optional, be aware that if you try to add a RATE_BASED rule to a web ACL without setting the type, the UpdateWebACL request will fail because the request tries to add a REGULAR rule with the specified ID, which does not exist.

          Possible values include:
          • "REGULAR"
          • "RATE_BASED"
          • "GROUP"
        • ExcludedRules — (Array<map>)

          An array of rules to exclude from a rule group. This is applicable only when the ActivatedRule refers to a RuleGroup.

          Sometimes it is necessary to troubleshoot rule groups that are blocking traffic unexpectedly (false positives). One troubleshooting technique is to identify the specific rule within the rule group that is blocking the legitimate traffic and then disable (exclude) that particular rule.

            • The second action inserts the same rule group back in, but specifying the rules to exclude. That is, the second Updates:Action should be INSERT, Updates:ActivatedRule:RuleId should be the rule group that you just removed, and ExcludedRules should contain the rules that you want to exclude.

          • RuleId — required — (String)

            The unique identifier for the rule to exclude from the rule group.

putLoggingConfiguration(params = {}, callback) ⇒ AWS.Request

Note: This is AWS WAF Classic documentation. For more information, see AWS WAF Classic in the developer guide. For the latest version of AWS WAF, use the AWS WAFV2 API and see the AWS WAF Developer Guide. With the latest version, AWS WAF has a single set of endpoints for regional and global use.

Associates a LoggingConfiguration with a specified web ACL.

You can access information about all traffic that AWS WAF inspects using the following steps:

  1. Create an Amazon Kinesis Data Firehose.

    Create the data firehose with a PUT source and in the region that you are operating. However, if you are capturing logs for Amazon CloudFront, always create the firehose in US East (N. Virginia).

    Note: Do not create the data firehose using a Kinesis stream as your source.

  2. Associate that firehose to your web ACL using a PutLoggingConfiguration request.

When you successfully enable logging using a PutLoggingConfiguration request, AWS WAF will create a service linked role with the necessary permissions to write logs to the Amazon Kinesis Data Firehose. For more information, see Logging Web ACL Traffic Information in the AWS WAF Developer Guide.

Service Reference:

Examples:

Calling the putLoggingConfiguration operation

var params = {
  LoggingConfiguration: { /* required */
    LogDestinationConfigs: [ /* required */
      'STRING_VALUE',
      /* more items */
    ],

    RedactedFields: [
      {
        Type: URI | QUERY_STRING | HEADER | METHOD | BODY | SINGLE_QUERY_ARG | ALL_QUERY_ARGS, /* required */
        Data: 'STRING_VALUE'
      },
      /* more items */
    ]
  }
};
wafregional.putLoggingConfiguration(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {}) —
    • LoggingConfiguration — (map)

      The Amazon Kinesis Data Firehose that contains the inspected traffic information, the redacted fields details, and the Amazon Resource Name (ARN) of the web ACL to monitor.

        An array of Amazon Kinesis Data Firehose ARNs.

      • RedactedFields — (Array<map>)

        The parts of the request that you want redacted from the logs. For example, if you redact the cookie field, the cookie field in the firehose will be xxx.

        • Type — required — (String)

          The part of the web request that you want AWS WAF to search for a specified string. Parts of a request that you can search include the following:

          • METHOD: The HTTP method, which indicated the type of operation that the request is asking the origin to perform. Amazon CloudFront supports the following methods: DELETE, GET, HEAD, OPTIONS, PATCH, POST, and PUT.

          • QUERY_STRING: A query string, which is the part of a URL that appears after a ? character, if any.

          • URI: The part of a web request that identifies a resource, for example, /images/daily-ad.jpg.

          • BODY: The part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form. The request body immediately follows the request headers. Note that only the first 8192 bytes of the request body are forwarded to AWS WAF for inspection. To allow or block requests based on the length of the body, you can create a size constraint set. For more information, see CreateSizeConstraintSet.

          • SINGLE_QUERY_ARG: The parameter in the query string that you will inspect, such as UserName or SalesRegion. The maximum length for SINGLE_QUERY_ARG is 30 characters.

          • ALL_QUERY_ARGS: Similar to SINGLE_QUERY_ARG, but rather than inspecting a single parameter, AWS WAF will inspect all parameters within the query for the value or regex pattern that you specify in TargetString.

          Possible values include:
          • "URI"
          • "QUERY_STRING"

updateByteMatchSet(params = {}, callback) ⇒ AWS.Request

Note: This is AWS WAF Classic documentation. For more information, see AWS WAF Classic in the developer guide. For the latest version of AWS WAF, use the AWS WAFV2 API and see the AWS WAF Developer Guide. With the latest version, AWS WAF has a single set of endpoints for regional and global use.

Inserts or deletes ByteMatchTuple objects (filters) in a ByteMatchSet. For each ByteMatchTuple object, you specify the following values:

  • Whether to insert or delete the object from the array. If you want to change a ByteMatchSetUpdate object, you delete the existing object and add a new one.

  • The part of a web request that you want AWS WAF to inspect, such as a query string or the value of the User-Agent header.

  • The bytes (typically a string that corresponds with ASCII characters) that you want AWS WAF to look for. For more information, including how you specify the values for the AWS WAF API and the AWS CLI or SDKs, see TargetString in the ByteMatchTuple data type.

  • Where to look, such as at the beginning or the end of a query string.

  • Whether to perform any conversions on the request, such as converting it to lowercase, before inspecting it for the specified string.

For example, you can add a ByteMatchSetUpdate object that matches web requests in which User-Agent headers contain the string BadBot. You can then configure AWS WAF to block those requests.

To create and configure a ByteMatchSet, perform the following steps:

  1. Create a ByteMatchSet. For more information, see CreateByteMatchSet.

  2. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateByteMatchSet request.

  3. Submit an UpdateByteMatchSet request to specify the part of the request that you want AWS WAF to inspect (for example, the header or the URI) and the value that you want AWS WAF to watch for.

For more information about how to use the AWS WAF API to allow or block HTTP requests, see the AWS WAF Developer Guide.

        Information about the part of a web request that you want AWS WAF to inspect and the value that you want AWS WAF to search for. If you specify DELETE for the value of Action, the ByteMatchTuple values must exactly match the values in the ByteMatchTuple that you want to delete from the ByteMatchSet.

        • FieldToMatch — required — (map)

          The part of a web request that you want AWS WAF to search, such as a specified header or a query string. For more information, see FieldToMatch.

          • Type — required — (String)

            The part of the web request that you want AWS WAF to search for a specified string. Parts of a request that you can search include the following:

            • HEADER: A specified request header, for example, the value of the User-Agent or Referer header. If you choose HEADER for the type, specify the name of the header in Data.

            • METHOD: The HTTP method, which indicated the type of operation that the request is asking the origin to perform. Amazon CloudFront supports the following methods: DELETE, GET, HEAD, OPTIONS, PATCH, POST, and PUT.

            • QUERY_STRING: A query string, which is the part of a URL that appears after a ? character, if any.

            • URI: The part of a web request that identifies a resource, for example, /images/daily-ad.jpg.

            • BODY: The part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form. The request body immediately follows the request headers. Note that only the first 8192 bytes of the request body are forwarded to AWS WAF for inspection. To allow or block requests based on the length of the body, you can create a size constraint set. For more information, see CreateSizeConstraintSet.

            • SINGLE_QUERY_ARG: The parameter in the query string that you will inspect, such as UserName or SalesRegion. The maximum length for SINGLE_QUERY_ARG is 30 characters.

            • ALL_QUERY_ARGS: Similar to SINGLE_QUERY_ARG, but rather than inspecting a single parameter, AWS WAF will inspect all parameters within the query for the value or regex pattern that you specify in TargetString.

            Possible values include:
            • "URI"
            • "QUERY_STRING"
            • "HEADER"
            • "METHOD"
            • "BODY"
            • "SINGLE_QUERY_ARG"
            • "ALL_QUERY_ARGS"
          • Data — (String)

            When the value of Type is HEADER, enter the name of the header that you want AWS WAF to search, for example, User-Agent or Referer. The name of the header is not case sensitive.

            When the value of Type is SINGLE_QUERY_ARG, enter the name of the parameter that you want AWS WAF to search, for example, UserName or SalesRegion. The parameter name is not case sensitive.

            If the value of Type is any other value, omit Data.

        • TargetString — required — (Buffer, Typed Array, Blob, String)

          The value that you want AWS WAF to search for. AWS WAF searches for the specified string in the part of web requests that you specified in FieldToMatch. The maximum length of the value is 50 bytes.

          Valid values depend on the values that you specified for FieldToMatch:

          • HEADER: The value that you want AWS WAF to search for in the request header that you specified in FieldToMatch, for example, the value of the User-Agent or Referer header.

          • METHOD: The HTTP method, which indicates the type of operation specified in the request. CloudFront supports the following methods: DELETE, GET, HEAD, OPTIONS, PATCH, POST, and PUT.

          • QUERY_STRING: The value that you want AWS WAF to search for in the query string, which is the part of a URL that appears after a ? character.

          • URI: The value that you want AWS WAF to search for in the part of a URL that identifies a resource, for example, /images/daily-ad.jpg.

          • BODY: The part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form. The request body immediately follows the request headers. Note that only the first 8192 bytes of the request body are forwarded to AWS WAF for inspection. To allow or block requests based on the length of the body, you can create a size constraint set. For more information, see CreateSizeConstraintSet.

          • SINGLE_QUERY_ARG: The parameter in the query string that you will inspect, such as UserName or SalesRegion. The maximum length for SINGLE_QUERY_ARG is 30 characters.

          • ALL_QUERY_ARGS: Similar to SINGLE_QUERY_ARG, but instead of inspecting a single parameter, AWS WAF inspects all parameters within the query string for the value or regex pattern that you specify in TargetString.

          If TargetString includes alphabetic characters A-Z and a-z, note that the value is case sensitive.

          If you're using the AWS WAF API

          Specify a base64-encoded version of the value. The maximum length of the value before you base64-encode it is 50 bytes.

          For example, suppose the value of Type is HEADER and the value of Data is User-Agent. If you want to search the User-Agent header for the value BadBot, you base64-encode BadBot using MIME base64-encoding and include the resulting value, QmFkQm90, in the value of TargetString.

          If you're using the AWS CLI or one of the AWS SDKs

          The value that you want AWS WAF to search for. The SDK automatically base64 encodes the value.

        • TextTransformation — required — (String)

          Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass AWS WAF. If you specify a transformation, AWS WAF performs the transformation on FieldToMatch before inspecting it for a match.

          You can only specify a single type of TextTransformation.

          CMD_LINE

          When you're concerned that attackers are injecting an operating system command line command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:

          • Delete the following characters: \ " ' ^

          • Delete spaces before the following characters: / (

          • Replace the following characters with a space: , ;

          • Replace multiple spaces with one space

          • Convert uppercase letters (A-Z) to lowercase (a-z)

          COMPRESS_WHITE_SPACE

          Use this option to replace the following characters with a space character (decimal 32):

          • \f, formfeed, decimal 12

          • \t, tab, decimal 9

          • \n, newline, decimal 10

          • \r, carriage return, decimal 13

          • \v, vertical tab, decimal 11

          • non-breaking space, decimal 160

          COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.

          HTML_ENTITY_DECODE

          Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:

          • Replaces (ampersand)quot; with "

          • Replaces (ampersand)nbsp; with a non-breaking space, decimal 160

          • Replaces (ampersand)lt; with a "less than" symbol

          • Replaces (ampersand)gt; with >

          • Replaces characters that are represented in hexadecimal format, (ampersand)#xhhhh;, with the corresponding characters

          • Replaces characters that are represented in decimal format, (ampersand)#nnnn;, with the corresponding characters

          LOWERCASE

          Use this option to convert uppercase letters (A-Z) to lowercase (a-z).

          URL_DECODE

          Use this option to decode a URL-encoded value.

          NONE

          Specify NONE if you don't want to perform any text transformations.

          Possible values include:
          • "NONE"
          • "COMPRESS_WHITE_SPACE"
          • "HTML_ENTITY_DECODE"
          • "LOWERCASE"
          • "CMD_LINE"
          • "URL_DECODE"
        • PositionalConstraint — required — (String)

          Within the portion of a web request that you want to search (for example, in the query string, if any), specify where you want AWS WAF to search. Valid values include the following:

          CONTAINS

          The specified part of the web request must include the value of TargetString, but the location doesn't matter.

          CONTAINS_WORD

          The specified part of the web request must include the value of TargetString, and TargetString must contain only alphanumeric characters or underscore (A-Z, a-z, 0-9, or ). In addition, TargetString must be a word, which means one of the following:

          • TargetString exactly matches the value of the specified part of the web request, such as the value of a header.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response) —

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error) —

      the error object returned from the request. Set to null if the request is successful.

    • data (Object) —

      the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

      • ChangeToken — (String)

        The ChangeToken that you used to submit the UpdateByteMatchSet request. You can also use this value to query the status of the request. For more information, see GetChangeTokenStatus.

Returns:

  • (AWS.Request) —

    a handle to the operation request for subsequent event callback registration.

updateGeoMatchSet(params = {}, callback) ⇒ AWS.Request

Note: This is AWS WAF Classic documentation. For more information, see AWS WAF Classic in the developer guide. For the latest version of AWS WAF, use the AWS WAFV2 API and see the AWS WAF Developer Guide. With the latest version, AWS WAF has a single set of endpoints for regional and global use.

Inserts or deletes GeoMatchConstraint objects in an GeoMatchSet. For each GeoMatchConstraint object, you specify the following values:

  • Whether to insert or delete the object from the array. If you want to change an GeoMatchConstraint object, you delete the existing object and add a new one.

  • The Type. The only valid value for Type is Country.

  • The Value, which is a two character code for the country to add to the GeoMatchConstraint object. Valid codes are listed in GeoMatchConstraint$Value.

To create and configure an GeoMatchSet, perform the following steps:

  1. Submit a CreateGeoMatchSet request.

  2. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateGeoMatchSet request.

  3. Submit an UpdateGeoMatchSet request to specify the country that you want AWS WAF to watch for.

When you update an GeoMatchSet, you specify the country that you want to add and/or the country that you want to delete. If you want to change a country, you delete the existing country and add the new one.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response) —

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error) —

      the error object returned from the request. Set to null if the request is successful.

    • data (Object) —

      the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

      • ChangeToken — (String)

        The ChangeToken that you used to submit the UpdateGeoMatchSet request. You can also use this value to query the status of the request. For more information, see GetChangeTokenStatus.

Returns:

  • (AWS.Request) —

    a handle to the operation request for subsequent event callback registration.

updateIPSet(params = {}, callback) ⇒ AWS.Request

Note: This is AWS WAF Classic documentation. For more information, see AWS WAF Classic in the developer guide. For the latest version of AWS WAF, use the AWS WAFV2 API and see the AWS WAF Developer Guide. With the latest version, AWS WAF has a single set of endpoints for regional and global use.

Inserts or deletes IPSetDescriptor objects in an IPSet. For each IPSetDescriptor object, you specify the following values:

  • Whether to insert or delete the object from the array. If you want to change an IPSetDescriptor object, you delete the existing object and add a new one.

  • The IP address version, IPv4 or IPv6.

  • The IP address in CIDR notation, for example, 192.0.2.0/24 (for the range of IP addresses from 192.0.2.0 to 192.0.2.255) or 192.0.2.44/32 (for the individual IP address 192.0.2.44).

AWS WAF supports IPv4 address ranges: /8 and any range between /16 through /32. AWS WAF supports IPv6 address ranges: /24, /32, /48, /56, /64, and /128. For more information about CIDR notation, see the Wikipedia entry Classless Inter-Domain Routing.

IPv6 addresses can be represented using any of the following formats:

  • 1111:0000:0000:0000:0000:0000:0000:0111/128

  • 1111:0:0:0:0:0:0:0111/128

  • 1111::0111/128

  • 1111::111/128

You use an IPSet to specify which web requests you want to allow or block based on the IP addresses that the requests originated from. For example, if you're receiving a lot of requests from one or a small number of IP addresses and you want to block the requests, you can create an IPSet that specifies those IP addresses, and then configure AWS WAF to block the requests.

To create and configure an IPSet, perform the following steps:

  1. Submit a CreateIPSet request.

  2. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateIPSet request.

  3. Submit an UpdateIPSet request to specify the IP addresses that you want AWS WAF to watch for.

When you update an IPSet, you specify the IP addresses that you want to add and/or the IP addresses that you want to delete. If you want to change an IP address, you delete the existing IP address and add the new one.

You can insert a maximum of 1000 addresses in a single request.

For more information about how to use the AWS WAF API to allow or block HTTP requests, see the AWS WAF Developer Guide.

      The value returned by the most recent call to GetChangeToken.

    • Updates — (Array<map>)

      An array of IPSetUpdate objects that you want to insert into or delete from an IPSet. For more information, see the applicable data types:

      You can insert a maximum of 1000 addresses in a single request.

      • Action — required — (String)

        Specifies whether to insert or delete an IP address with UpdateIPSet.

        Possible values include:
        • "INSERT"
        • "DELETE"
      • IPSetDescriptor — required — (map)

        The IP address type (IPV4 or IPV6) and the IP address range (in CIDR notation) that web requests originate from.

        • Type — required — (String)

          Specify IPV4 or IPV6.

          Possible values include:
          • "IPV4"

          Specify an IPv6 address by using CIDR notation. For example:

          • To configure AWS WAF to allow, block, or count requests that originated from the IP address 1111:0000:0000:0000:0000:0000:0000:0111, specify 1111:0000:0000:0000:0000:0000:0000:0111/128.

          • To configure AWS WAF to allow, block, or count requests that originated from IP addresses 1111:0000:0000:0000:0000:0000:0000:0000 to 1111:0000:0000:0000:ffff:ffff:ffff:ffff, specify 1111:0000:0000:0000:0000:0000:0000:0000/64.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response) —

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error) —

      the error object returned from the request. Set to null if the request is successful.

    • data (Object) —

      the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

      • ChangeToken — (String)

        The ChangeToken that you used to submit the UpdateIPSet request. You can also use this value to query the status of the request. For more information, see GetChangeTokenStatus.

Returns:

  • (AWS.Request) —

    a handle to the operation request for subsequent event callback registration.

updateRateBasedRule(params = {}, callback) ⇒ AWS.Request

Note: This is AWS WAF Classic documentation. For more information, see AWS WAF Classic in the developer guide. For the latest version of AWS WAF, use the AWS WAFV2 API and see the AWS WAF Developer Guide. With the latest version, AWS WAF has a single set of endpoints for regional and global use.

Inserts or deletes Predicate objects in a rule and updates the RateLimit in the rule.

Each Predicate object identifies a predicate, such as a ByteMatchSet or an IPSet, that specifies the web requests that you want to block or count. The RateLimit specifies the number of requests every five minutes that triggers the rule.

If you add more than one predicate to a RateBasedRule, a request must match all the predicates and exceed the RateLimit to be counted or blocked. For example, suppose you add the following to a RateBasedRule:

  • An IPSet that matches the IP address 192.0.2.44/32

  • A ByteMatchSet that matches BadBot in the User-Agent header

Further, you specify a RateLimit of 1,000.

You then add the RateBasedRule to a WebACL and specify that you want to block requests that satisfy the rule. For a request to be blocked, it must come from the IP address 192.0.2.44 and the User-Agent header in the request must contain the value BadBot. Further, requests that match these two conditions much be received at a rate of more than 1,000 every five minutes. If the rate drops below this limit, AWS WAF no longer blocks the requests.

As a second example, suppose you want to limit requests to a particular page on your site. To do this, you could add the following to a RateBasedRule:

  • A ByteMatchSet with FieldToMatch of URI

  • A PositionalConstraint of STARTS_WITH

  • A TargetString of login

Further, you specify a RateLimit of 1,000.

By adding this RateBasedRule to a WebACL, you could limit requests to your login page without affecting the rest of your site.

        • "INSERT"
        • "DELETE"
      • Predicate — required — (map)

        The ID of the Predicate (such as an IPSet) that you want to add to a Rule.

        • Negated — required — (Boolean)

          Set Negated to False if you want AWS WAF to allow, block, or count requests based on the settings in the specified ByteMatchSet, IPSet, SqlInjectionMatchSet, XssMatchSet, RegexMatchSet, GeoMatchSet, or SizeConstraintSet. For example, if an IPSet includes the IP address 192.0.2.44, AWS WAF will allow or block requests based on that IP address.

          Set Negated to True if you want AWS WAF to allow or block a request based on the negation of the settings in the ByteMatchSet, IPSet, SqlInjectionMatchSet, XssMatchSet, RegexMatchSet, GeoMatchSet, or SizeConstraintSet. For example, if an IPSet includes the IP address 192.0.2.44, AWS WAF will allow, block, or count requests based on all IP addresses except 192.0.2.44.

        • Type — required — (String)

          A unique identifier for a predicate in a Rule, such as ByteMatchSetId or IPSetId. The ID is returned by the corresponding Create or List command.

    • RateLimit — (Integer)

      The maximum number of requests, which have an identical value in the field specified by the RateKey, allowed in a five-minute period. If the number of requests exceeds the RateLimit and the other predicates specified in the rule are also met, AWS WAF triggers the action that is specified for this rule.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response) —

      the response object containing error, data properties, and the original request object.

    Parameters:

updateRegexMatchSet(params = {}, callback) ⇒ AWS.Request

Note: This is AWS WAF Classic documentation. For more information, see AWS WAF Classic in the developer guide. For the latest version of AWS WAF, use the AWS WAFV2 API and see the AWS WAF Developer Guide. With the latest version, AWS WAF has a single set of endpoints for regional and global use.

Inserts or deletes RegexMatchTuple objects (filters) in a RegexMatchSet. For each RegexMatchSetUpdate object, you specify the following values:

  • Whether to insert or delete the object from the array. If you want to change a RegexMatchSetUpdate object, you delete the existing object and add a new one.

  • The part of a web request that you want AWS WAF to inspectupdate, such as a query string or the value of the User-Agent header.

  • The identifier of the pattern (a regular expression) that you want AWS WAF to look for. For more information, see RegexPatternSet.

  • Whether to perform any conversions on the request, such as converting it to lowercase, before inspecting it for the specified string.

For example, you can create a RegexPatternSet that matches any requests with User-Agent headers that contain the string B[a@]dB[o0]t. You can then configure AWS WAF to reject those requests.

To create and configure a RegexMatchSet, perform the following steps:

  1. Create a RegexMatchSet. For more information, see CreateRegexMatchSet.

  2. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateRegexMatchSet request.

  3. Submit an UpdateRegexMatchSet request to specify the part of the request that you want AWS WAF to inspect (for example, the header or the URI) and the identifier of the RegexPatternSet that contain the regular expression patters you want AWS WAF to watch for.

For more information about how to use the AWS WAF API to allow or block HTTP requests, see the AWS WAF Developer Guide.

});

Parameters:

  • params (Object) (defaults to: {}) —
    • RegexMatchSetId — (String)

      The RegexMatchSetId of the RegexMatchSet that you want to update. RegexMatchSetId is returned by CreateRegexMatchSet and by ListRegexMatchSets.

    • Updates — (Array<map>)

      An array of RegexMatchSetUpdate objects that you want to insert into or delete from a RegexMatchSet. For more information, see RegexMatchTuple.

      • Action — required — (String)

        Specifies whether to insert or delete a RegexMatchTuple.

        Possible values include:
        • "INSERT"
        • "DELETE"
      • RegexMatchTuple — required — (map)

        Information about the part of a web request that you want AWS WAF to inspect and the identifier of the regular expression (regex) pattern that you want AWS WAF to search for. If you specify DELETE for the value of Action, the RegexMatchTuple values must exactly match the values in the RegexMatchTuple that you want to delete from the RegexMatchSet.

        • FieldToMatch — required — (map)

          Specifies where in a web request to look for the RegexPatternSet.

          • Type — required — (String)

            The part of the web request that you want AWS WAF to search for a specified string. Parts of a request that you can search include the following:

            • HEADER: A specified request header, for example, the value of the User-Agent or Referer header. If you choose HEADER for the type, specify the name of the header in Data.

            • METHOD: The HTTP method, which indicated the type of operation that the request is asking the origin to perform. Amazon CloudFront supports the following methods: DELETE, GET, HEAD, OPTIONS, PATCH, POST, and PUT.

            • QUERY_STRING: A query string, which is the part of a URL that appears after a ? character, if any.

            • URI: The part of a web request that identifies a resource, for example, /images/daily-ad.jpg.

            • BODY: The part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form. The request body immediately follows the request headers. Note that only the first 8192 bytes of the request body are forwarded to AWS WAF for inspection. To allow or block requests based on the length of the body, you can create a size constraint set. For more information, see CreateSizeConstraintSet.

            • SINGLE_QUERY_ARG: The parameter in the query string that you will inspect, such as UserName or SalesRegion. The maximum length for SINGLE_QUERY_ARG is 30 characters.

            • ALL_QUERY_ARGS: Similar to SINGLE_QUERY_ARG, but rather than inspecting a single parameter, AWS WAF will inspect all parameters within the query for the value or regex pattern that you specify in TargetString.

            Possible values include:
            • "URI"
            • "QUERY_STRING"
            • "HEADER"
            • "METHOD"
            • "BODY"

            When the value of Type is HEADER, enter the name of the header that you want AWS WAF to search, for example, User-Agent or Referer. The name of the header is not case sensitive.

            When the value of Type is SINGLE_QUERY_ARG, enter the name of the parameter that you want AWS WAF to search, for example, UserName or SalesRegion. The parameter name is not case sensitive.

            If the value of Type is any other value, omit Data.

        • TextTransformation — required — (String)

          Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass AWS WAF. If you specify a transformation, AWS WAF performs the transformation on RegexPatternSet before inspecting a request for a match.

          You can only specify a single type of TextTransformation.

          CMD_LINE

          When you're concerned that attackers are injecting an operating system commandline command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:

          • Delete the following characters: \ " ' ^

          • Delete spaces before the following characters: / (

          • Replace the following characters with a space: , ;

          • Replace multiple spaces with one space

          • Convert uppercase letters (A-Z) to lowercase (a-z)

          COMPRESS_WHITE_SPACE

          Use this option to replace the following characters with a space character (decimal 32):

          • \f, formfeed, decimal 12

          • \t, tab, decimal 9

          • \n, newline, decimal 10

          • \r, carriage return, decimal 13

          • \v, vertical tab, decimal 11

          • non-breaking space, decimal 160

          COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.

          HTML_ENTITY_DECODE

          Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:

          • Replaces (ampersand)quot; with "

          • Replaces (ampersand)nbsp; with a non-breaking space, decimal 160

          • Replaces (ampersand)lt; with a "less than" symbol

          • Replaces (ampersand)gt; with >

          • Replaces characters that are represented in hexadecimal format, (ampersand)#xhhhh;, with the corresponding characters

          • Replaces characters that are represented in decimal format, (ampersand)#nnnn;, with the corresponding characters

          LOWERCASE

          Use this option to convert uppercase letters (A-Z) to lowercase (a-z).

          URL_DECODE

          Use this option to decode a URL-encoded value.

          NONE

          Specify NONE if you don't want to perform any text transformations.

          Possible values include:
          • "NONE"
          • "COMPRESS_WHITE_SPACE"
          • "HTML_ENTITY_DECODE"

          • "CMD_LINE"
          • "URL_DECODE"
        • RegexPatternSetId — required — (String)

          The RegexPatternSetId for a RegexPatternSet. You use RegexPatternSetId to get information about a RegexPatternSet (see GetRegexPatternSet), update a RegexPatternSet (see UpdateRegexPatternSet), insert a RegexPatternSet into a RegexMatchSet or delete one from a RegexMatchSet (see UpdateRegexMatchSet), and delete an RegexPatternSet from AWS WAF (see DeleteRegexPatternSet).

          RegexPatternSetId is returned by CreateRegexPatternSet and by ListRegexPatternSets.

    • ChangeToken — (String)

      The value returned by the most recent call to GetChangeToken.

Callback (callback):

Inserts or deletes Predicate objects in a Rule. Each Predicate object identifies a predicate, such as a ByteMatchSet or an IPSet, that specifies the web requests that you want to allow, block, or count. If you add more than one predicate to a Rule, a request must match all of the specifications to be allowed, blocked, or counted. For example, suppose that you add the following to a Rule:

  • A ByteMatchSet that matches the value BadBot in the User-Agent header

  • An IPSet that matches the IP address 192.0.2.44

You then add the Rule to a WebACL and specify that you want to block requests that satisfy the Rule. For a request to be blocked, the User-Agent header in the request must contain the value BadBot and the request must originate from the IP address 192.0.2.44.

To create and configure a Rule, perform the following steps:

  1. Create and update the predicates that you want to include in the Rule.

  2. Create the Rule. See CreateRule.

  3. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateRule request.

  4. Submit an UpdateRule request to add predicates to the Rule.

  5. Create and update a WebACL that contains the Rule. See CreateWebACL.

If you want to replace one ByteMatchSet or IPSet with another, you delete the existing one and add the new one.

      An array of RuleUpdate objects that you want to insert into or delete from a Rule. For more information, see the applicable data types:

      • Action — required — (String)

        Specify INSERT to add a Predicate to a Rule. Use DELETE to remove a Predicate from a Rule.

        Possible values include:
        • "INSERT"
        • "DELETE"
      • Predicate — required — (map)

        The ID of the Predicate (such as an IPSet) that you want to add to a Rule.

        • Negated — required — (Boolean)

          Set Negated to False if you want AWS WAF to allow, block, or count requests based on the settings in the specified ByteMatchSet, IPSet, SqlInjectionMatchSet, XssMatchSet, RegexMatchSet, GeoMatchSet, or SizeConstraintSet. For example, if an IPSet includes the IP address 192.0.2.44, AWS WAF will allow or block requests based on that IP address.

          Set Negated to True if you want AWS WAF to allow or block a request based on the negation of the settings in the ByteMatchSet, IPSet, SqlInjectionMatchSet, XssMatchSet, RegexMatchSet, GeoMatchSet, or SizeConstraintSet. For example, if an IPSet includes the IP address 192.0.2.44, AWS WAF will allow, block, or count requests based on all IP addresses except 192.0.2.44.

        • Type — required — (String)

          The type of predicate in a Rule, such as ByteMatch or IPSet.

          Possible values include:
          • "IPMatch"
          • "ByteMatch"
          • "SqlInjectionMatch"
          • "GeoMatch"
          • "SizeConstraint"
          • "XssMatch"
          • "RegexMatch"
        • DataId — required — (String)

          A unique identifier for a predicate in a Rule, such as ByteMatchSetId or IPSetId. The ID is returned by the corresponding Create or List command.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error) —

      the error object returned from the request. Set to null if the request is successful.

    • data (Object) —

      the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

      • ChangeToken — (String)

        The ChangeToken that you used to submit the UpdateRule request. You can also use this value to query the status of the request. For more information, see GetChangeTokenStatus.

updateRuleGroup(params = {}, callback) ⇒ AWS.Request

Note: This is AWS WAF Classic documentation. For more information, see AWS WAF Classic in the developer guide. For the latest version of AWS WAF, use the AWS WAFV2 API and see the AWS WAF Developer Guide. With the latest version, AWS WAF has a single set of endpoints for regional and global use.

Inserts or deletes ActivatedRule objects in a RuleGroup.

You can only insert REGULAR rules into a rule group.

You can have a maximum of ten rules per rule group.

To create and configure a RuleGroup, perform the following steps:

  1. Create and update the Rules that you want to include in the RuleGroup. See CreateRule.

  2. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateRuleGroup request.

  3. Submit an UpdateRuleGroup request to add Rules to the RuleGroup.

  4. Create and update a WebACL that contains the RuleGroup. See CreateWebACL.

If you want to replace one Rule with another, you delete the existing one and add the new one.

For more information about how to use the AWS WAF API to allow or block HTTP requests, see the AWS WAF Developer Guide.

        },
        Type: REGULAR | RATE_BASED | GROUP
      }
    },
    /* more items */
  ]
};
wafregional.updateRuleGroup(params, function(err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {}) —
    • RuleGroupId — (String)

      The RuleGroupId of the RuleGroup that you want to update. RuleGroupId is returned by CreateRuleGroup and by ListRuleGroups.

    • Updates — (Array<map>)

      An array of RuleGroupUpdate objects that you want to insert into or delete from a RuleGroup.

      You can only insert REGULAR rules into a rule group.

      ActivatedRule|OverrideAction applies only when updating or adding a RuleGroup to a WebACL. In this case you do not use ActivatedRule|Action. For all other update requests, ActivatedRule|Action is used instead of ActivatedRule|OverrideAction.

      • Action — required — (String)

        Specify INSERT to add an ActivatedRule to a RuleGroup. Use DELETE to remove an ActivatedRule from a RuleGroup.

        Possible values include:
        • "INSERT"
        • "DELETE"
      • ActivatedRule — required — (map)

        The ActivatedRule object specifies a Rule that you want to insert or delete, the priority of the Rule in the WebACL, and the action that you want AWS WAF to take when a web request matches the Rule (ALLOW, BLOCK, or COUNT).

        • Priority — required — (Integer)

          Specifies the order in which the Rules in a WebACL are evaluated. Rules with a lower value for Priority are evaluated before Rules with a higher value. The value must be a unique integer. If you add multiple Rules to a WebACL, the values don't need to be consecutive.

        • RuleId — required — (String)

          The RuleId for a Rule. You use RuleId to get more information about a Rule (see GetRule), update a Rule (see UpdateRule), insert a Rule into a WebACL or delete a one from a WebACL (see UpdateWebACL), or delete a Rule from AWS WAF (see DeleteRule).

          RuleId is returned by CreateRule and by ListRules.

        • Action — (map)

          Specifies the action that CloudFront or AWS WAF takes when a web request matches the conditions in the Rule. Valid values for Action include the following:

          • ALLOW: CloudFront responds with the requested object.

          • BLOCK: CloudFront responds with an HTTP 403 (Forbidden) status code.

          • COUNT: AWS WAF increments a counter of requests that match the conditions in the rule and then continues to inspect the web request based on the remaining rules in the web ACL.

          ActivatedRule|OverrideAction applies only when updating or adding a RuleGroup to a WebACL. In this case, you do not use ActivatedRule|Action. For all other update requests, ActivatedRule|Action is used instead of ActivatedRule|OverrideAction.

          • Type — required — (String)

            Specifies how you want AWS WAF to respond to requests that match the settings in a Rule. Valid settings include the following:

            • ALLOW: AWS WAF allows requests

            • BLOCK: AWS WAF blocks requests

            • COUNT: AWS WAF increments a counter of the requests that match all of the conditions in the rule. AWS WAF then continues to inspect the web request based on the remaining rules in the web ACL. You can't specify COUNT for the default action for a WebACL.

            Possible values include:
            • "BLOCK"
            • "ALLOW"
            • "COUNT"
        • OverrideAction — (map)

          Use the OverrideAction to test your RuleGroup.

          Any rule in a RuleGroup can potentially block a request. If you set the OverrideAction to None, the RuleGroup will block a request if any individual rule in the RuleGroup matches the request and is configured to block that request. However if you first want to test the RuleGroup, set the OverrideAction to Count. The RuleGroup will then override any block action specified by individual rules contained within the group. Instead of blocking matching requests, those requests will be counted. You can view a record of counted requests using GetSampledRequests.

          ActivatedRule|OverrideAction applies only when updating or adding a RuleGroup to a WebACL. In this case you do not use ActivatedRule|Action. For all other update requests, ActivatedRule|Action is used instead of ActivatedRule|OverrideAction.

          • Type — required — (String)

            COUNT overrides the action specified by the individual rule within a RuleGroup . If set to NONE, the rule's action will take place.

            Possible values include:
            • "NONE"
            • "COUNT"
        • Type — (String)

          The rule type, either REGULAR, as defined by Rule, RATE_BASED, as defined by RateBasedRule, or GROUP, as defined by RuleGroup. The default is REGULAR. Although this field is optional, be aware that if you try to add a RATE_BASED rule to a web ACL without setting the type, the UpdateWebACL request will fail because the request tries to add a REGULAR rule with the specified ID, which does not exist.

          Possible values include:
          • "REGULAR"
          • "RATE_BASED"
          • "GROUP"
        • ExcludedRules — (Array<map>)

          An array of rules to exclude from a rule group. This is applicable only when the ActivatedRule refers to a RuleGroup.

          Sometimes it is necessary to troubleshoot rule groups that are blocking traffic unexpectedly (false positives). One troubleshooting technique is to identify the specific rule within the rule group that is blocking the legitimate traffic and then disable (exclude) that particular rule. You can exclude rules from both your own rule groups and AWS Marketplace rule groups that have been associated with a web ACL.

          Specifying ExcludedRules does not remove those rules from the rule group. Rather, it changes the action for the rules to COUNT. Therefore, requests that match an ExcludedRule are counted but not blocked. The RuleGroup owner will receive COUNT metrics for each ExcludedRule.

          If you want to exclude rules from a rule group that is already associated with a web ACL, perform the following steps:

          1. Use the AWS WAF logs to identify the IDs of the rules that you want to exclude. For more information about the logs, see Logging Web ACL Traffic Information.

          2. Submit an UpdateWebACL request that has two actions:

            • The first action deletes the existing rule group from the web ACL. That is, in the UpdateWebACL request, the first Updates:Action should be DELETE and Updates:ActivatedRule:RuleId should be the rule group that contains the rules that you want to exclude.

            • The second action inserts the same rule group back in, but specifying the rules to exclude. That is, the second Updates:Action should be INSERT, Updates:ActivatedRule:RuleId should be the rule group that you just removed, and ExcludedRules should contain the rules that you want to exclude.

          • RuleId — required — (String)

            The unique identifier for the rule to exclude from the rule group.

    • ChangeToken — (String)

      The value returned by the most recent call to GetChangeToken.

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response) —

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error) —

      the error object returned from the request. Set to null if the request is successful.

    • data (Object) —

      the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

      • ChangeToken — (String)

        The ChangeToken that you used to submit the UpdateRuleGroup request. You can also use this value to query the status of the request. For more information, see GetChangeTokenStatus.

Returns:

  • (AWS.Request) —

    a handle to the operation request for subsequent event callback registration.

updateSizeConstraintSet(params = {}, callback) ⇒ AWS.Request

Note: This is AWS WAF Classic documentation. For more information, see AWS WAF Classic in the developer guide. For the latest version of AWS WAF, use the AWS WAFV2 API and see the AWS WAF Developer Guide. With the latest version, AWS WAF has a single set of endpoints for regional and global use.

Inserts or deletes SizeConstraint objects (filters) in a SizeConstraintSet. For each SizeConstraint object, you specify the following values:

  • Whether to insert or delete the object from the array. If you want to change a SizeConstraintSetUpdate object, you delete the existing object and add a new one.

  • The part of a web request that you want AWS WAF to evaluate, such as the length of a query string or the length of the User-Agent header.

  • Whether to perform any transformations on the request, such as converting it to lowercase, before checking its length. Note that transformations of the request body are not supported because the AWS resource forwards only the first 8192 bytes of your request to AWS WAF.

    You can only specify a single type of TextTransformation.

  • A ComparisonOperator used for evaluating the selected part of the request against the specified Size, such as equals, greater than, less than, and so on.

  • The length, in bytes, that you want AWS WAF to watch for in selected part of the request. The length is computed after applying the transformation.

For example, you can add a SizeConstraintSetUpdate object that matches web requests in which the length of the User-Agent header is greater than 100 bytes. You can then configure AWS WAF to block those requests.

To create and configure a SizeConstraintSet, perform the following steps:

  1. Create a SizeConstraintSet. For more information, see CreateSizeConstraintSet.

  2. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateSizeConstraintSet request.

  3. Submit an UpdateSizeConstraintSet request to specify the part of the request that you want AWS WAF to inspect (for example, the header or the URI) and the value that you want AWS WAF to watch for.

For more information about how to use the AWS WAF API to allow or block HTTP requests, see the AWS WAF Developer Guide.

});

Parameters:

  • params (Object) (defaults to: {}) —
    • SizeConstraintSetId — (String)

      The SizeConstraintSetId of the SizeConstraintSet that you want to update. SizeConstraintSetId is returned by CreateSizeConstraintSet and by ListSizeConstraintSets.

    • ChangeToken — (String)

      The value returned by the most recent call to GetChangeToken.

    • Updates — (Array<map>)

      An array of SizeConstraintSetUpdate objects that you want to insert into or delete from a SizeConstraintSet. For more information, see the applicable data types:

      • Action — required — (String)

        Specify INSERT to add a SizeConstraintSetUpdate to a SizeConstraintSet. Use DELETE to remove a SizeConstraintSetUpdate from a SizeConstraintSet.

        Possible values include:
        • "INSERT"
        • "DELETE"
      • SizeConstraint — required — (map)

        Specifies a constraint on the size of a part of the web request. AWS WAF uses the Size, ComparisonOperator, and FieldToMatch to build an expression in the form of "Size ComparisonOperator size in bytes of FieldToMatch". If that expression is true, the SizeConstraint is considered to match.

        • FieldToMatch — required — (map)

          Specifies where in a web request to look for the size constraint.

          • Type — required — (String)

            The part of the web request that you want AWS WAF to search for a specified string. Parts of a request that you can search include the following:

            • HEADER: A specified request header, for example, the value of the User-Agent or Referer header. If you choose HEADER for the type, specify the name of the header in Data.

            • METHOD: The HTTP method, which indicated the type of operation that the request is asking the origin to perform. Amazon CloudFront supports the following methods: DELETE, GET, HEAD, OPTIONS, PATCH, POST, and PUT.

            • QUERY_STRING: A query string, which is the part of a URL that appears after a ? character, if any.

            • URI: The part of a web request that identifies a resource, for example, /images/daily-ad.jpg.

            • BODY: The part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form. The request body immediately follows the request headers. Note that only the first 8192 bytes of the request body are forwarded to AWS WAF for inspection. To allow or block requests based on the length of the body, you can create a size constraint set. For more information, see CreateSizeConstraintSet.

            • SINGLE_QUERY_ARG: The parameter in the query string that you will inspect, such as UserName or SalesRegion. The maximum length for SINGLE_QUERY_ARG is 30 characters.

            • ALL_QUERY_ARGS: Similar to SINGLE_QUERY_ARG, but rather than inspecting a single parameter, AWS WAF will inspect all parameters within the query for the value or regex pattern that you specify in TargetString.

            Possible values include:
            • "URI"
            • "QUERY_STRING"
            • "HEADER"
            • "METHOD"
            • "BODY"
            • "SINGLE_QUERY_ARG"
            • "ALL_QUERY_ARGS"
          • Data — (String)

            When the value of Type is HEADER, enter the name of the header that you want AWS WAF to search, for example, User-Agent or Referer. The name of the header is not case sensitive.

            When the value of Type is SINGLE_QUERY_ARG, enter the name of the parameter that you want AWS WAF to search, for example, UserName or SalesRegion. The parameter name is not case sensitive.

            If the value of Type is any other value, omit Data.

        • TextTransformation — required — (String)

          Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass AWS WAF. If you specify a transformation, AWS WAF performs the transformation on FieldToMatch before inspecting it for a match.

          You can only specify a single type of TextTransformation.

          Note that if you choose BODY for the value of Type, you must choose NONE for TextTransformation because CloudFront forwards only the first 8192 bytes for inspection.

          NONE

          Specify NONE if you don't want to perform any text transformations.

          CMD_LINE

          When you're concerned that attackers are injecting an operating system command line command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:

          • Delete the following characters: \ " ' ^

          • Delete spaces before the following characters: / (

          • Replace the following characters with a space: , ;

          • Replace multiple spaces with one space

          • Convert uppercase letters (A-Z) to lowercase (a-z)

          COMPRESS_WHITE_SPACE

          Use this option to replace the following characters with a space character (decimal 32):

          • \f, formfeed, decimal 12

          • \t, tab, decimal 9

          • \n, newline, decimal 10

          • \r, carriage return, decimal 13

          • \v, vertical tab, decimal 11

          • non-breaking space, decimal 160

          COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.

          HTML_ENTITY_DECODE

          Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:

          • Replaces (ampersand)quot; with "

          • Replaces (ampersand)nbsp; with a non-breaking space, decimal 160

          • Replaces (ampersand)lt; with a "less than" symbol

          • Replaces (ampersand)gt; with >

          • Replaces characters that are represented in hexadecimal format, (ampersand)#xhhhh;, with the corresponding characters

          • Replaces characters that are represented in decimal format, (ampersand)#nnnn;, with the corresponding characters

          LOWERCASE

          Use this option to convert uppercase letters (A-Z) to lowercase (a-z).

          URL_DECODE

          Use this option to decode a URL-encoded value.

          Possible values include:
          • "NONE"
          • "COMPRESS_WHITE_SPACE"
          • "HTML_ENTITY_DECODE"
          • "LOWERCASE"
          • "CMD_LINE"
          • "URL_DECODE"
        • ComparisonOperator — required — (String)

          The type of comparison you want AWS WAF to perform. AWS WAF uses this in combination with the provided Size and FieldToMatch to build an expression in the form of "Size ComparisonOperator size in bytes of FieldToMatch". If that expression is true, the SizeConstraint is considered to match.

          EQ: Used to test if the Size is equal to the size of the FieldToMatch

          NE: Used to test if the Size is not equal to the size of the FieldToMatch

          LE: Used to test if the Size is less than or equal to the size of the FieldToMatch

          LT: Used to test if the Size is strictly less than the size of the FieldToMatch

          GE: Used to test if the Size is greater than or equal to the size of the FieldToMatch

          GT: Used to test if the Size is strictly greater than the size of the FieldToMatch

          Possible values include:
          • "EQ"
          • "NE"
          • "LE"
          • "LT"
          • "GE"
          • "GT"
        • Size — required — (Integer)

          The size in bytes that you want AWS WAF to compare against the size of the specified FieldToMatch. AWS WAF uses this in combination with ComparisonOperator and FieldToMatch to build an expression in the form of "Size ComparisonOperator size in bytes of FieldToMatch". If that expression is true, the SizeConstraint is considered to match.

          Valid values for size are 0 - 21474836480 bytes (0 - 20 GB).

          If you specify URI for the value of Type, the / in the URI counts as one character. For example, the URI /logo.jpg is nine characters long.

      • ChangeToken — (String)

        The ChangeToken that you used to submit the UpdateSizeConstraintSet request. You can also use this value to query the status of the request. For more information, see GetChangeTokenStatus.

Returns:

  • (AWS.Request) —

    a handle to the operation request for subsequent event callback registration.

updateSqlInjectionMatchSet(params = {}, callback) ⇒ AWS.Request

Note: This is AWS WAF Classic documentation. For more information, see AWS WAF Classic in the developer guide. For the latest version of AWS WAF, use the AWS WAFV2 API and see the AWS WAF Developer Guide. With the latest version, AWS WAF has a single set of endpoints for regional and global use.

Inserts or deletes SqlInjectionMatchTuple objects (filters) in a SqlInjectionMatchSet. For each SqlInjectionMatchTuple object, you specify the following values:

  • Action: Whether to insert the object into or delete the object from the array. To change a SqlInjectionMatchTuple, you delete the existing object and add a new one.

  • FieldToMatch: The part of web requests that you want AWS WAF to inspect and, if you want AWS WAF to inspect a header or custom query parameter, the name of the header or parameter.

  • TextTransformation: Which text transformation, if any, to perform on the web request before inspecting the request for snippets of malicious SQL code.

    You can only specify a single type of TextTransformation.

You use SqlInjectionMatchSet objects to specify which CloudFront requests that you want to allow, block, or count. For example, if you're receiving requests that contain snippets of SQL code in the query string and you want to block the requests, you can create a SqlInjectionMatchSet with the applicable settings, and then configure AWS WAF to block the requests.

To create and configure a SqlInjectionMatchSet, perform the following steps:

  1. Submit a CreateSqlInjectionMatchSet request.

  2. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateIPSet request.

  3. Submit an UpdateSqlInjectionMatchSet request to specify the parts of web requests that you want AWS WAF to inspect for snippets of SQL code.

For more information about how to use the AWS WAF API to allow or block HTTP requests, see the AWS WAF Developer Guide.

  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {}) —
    • SqlInjectionMatchSetId — (String)

      The SqlInjectionMatchSetId of the SqlInjectionMatchSet that you want to update. SqlInjectionMatchSetId is returned by CreateSqlInjectionMatchSet and by ListSqlInjectionMatchSets.

    • ChangeToken — (String)

      The value returned by the most recent call to GetChangeToken.

    • Updates — (Array<map>)

      An array of SqlInjectionMatchSetUpdate objects that you want to insert into or delete from a SqlInjectionMatchSet. For more information, see the applicable data types:

      • Action — required — (String)

        Specify INSERT to add a SqlInjectionMatchSetUpdate to a SqlInjectionMatchSet. Use DELETE to remove a SqlInjectionMatchSetUpdate from a SqlInjectionMatchSet.

        Possible values include:
        • "INSERT"
        • "DELETE"
      • SqlInjectionMatchTuple — required — (map)

        Specifies the part of a web request that you want AWS WAF to inspect for snippets of malicious SQL code and, if you want AWS WAF to inspect a header, the name of the header.

        • FieldToMatch — required — (map)

          Specifies where in a web request to look for snippets of malicious SQL code.

          • Type — required — (String)

            The part of the web request that you want AWS WAF to search for a specified string. Parts of a request that you can search include the following:

            • HEADER: A specified request header, for example, the value of the User-Agent or Referer header. If you choose HEADER for the type, specify the name of the header in Data.

            • METHOD: The HTTP method, which indicated the type of operation that the request is asking the origin to perform. Amazon CloudFront supports the following methods: DELETE, GET, HEAD, OPTIONS, PATCH, POST, and PUT.

            • QUERY_STRING: A query string, which is the part of a URL that appears after a ? character, if any.

            • URI: The part of a web request that identifies a resource, for example, /images/daily-ad.jpg.

            • BODY: The part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form. The request body immediately follows the request headers. Note that only the first 8192 bytes of the request body are forwarded to AWS WAF for inspection. To allow or block requests based on the length of the body, you can create a size constraint set. For more information, see CreateSizeConstraintSet.

            • SINGLE_QUERY_ARG: The parameter in the query string that you will inspect, such as UserName or SalesRegion. The maximum length for SINGLE_QUERY_ARG is 30 characters.

            • ALL_QUERY_ARGS: Similar to SINGLE_QUERY_ARG, but rather than inspecting a single parameter, AWS WAF will inspect all parameters within the query for the value or regex pattern that you specify in TargetString.

            Possible values include:
            • "URI"
            • "QUERY_STRING"
            • "HEADER"
            • "METHOD"
            • "BODY"
            • "SINGLE_QUERY_ARG"
            • "ALL_QUERY_ARGS"
          • Data — (String)

            When the value of Type is HEADER, enter the name of the header that you want AWS WAF to search, for example, User-Agent or Referer. The name of the header is not case sensitive.

            When the value of Type is SINGLE_QUERY_ARG, enter the name of the parameter that you want AWS WAF to search, for example, UserName or SalesRegion. The parameter name is not case sensitive.

            If the value of Type is any other value, omit Data.

        • TextTransformation — required — (String)

          Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass AWS WAF. If you specify a transformation, AWS WAF performs the transformation on FieldToMatch before inspecting it for a match.

          You can only specify a single type of TextTransformation.

          CMD_LINE

          When you're concerned that attackers are injecting an operating system command line command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:

          • Delete the following characters: \ " ' ^

          • Delete spaces before the following characters: / (

          • Replace the following characters with a space: , ;

          • Replace multiple spaces with one space

          • Convert uppercase letters (A-Z) to lowercase (a-z)

          COMPRESS_WHITE_SPACE

          Use this option to replace the following characters with a space character (decimal 32):

          • \f, formfeed, decimal 12

          • \t, tab, decimal 9

          • \n, newline, decimal 10

          • \r, carriage return, decimal 13

          • \v, vertical tab, decimal 11

          • non-breaking space, decimal 160

          COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.

          HTML_ENTITY_DECODE

          Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:

          • Replaces (ampersand)quot; with "

          • Replaces (ampersand)nbsp; with a non-breaking space, decimal 160

          • Replaces (ampersand)lt; with a "less than" symbol

          • Replaces (ampersand)gt; with >

          • Replaces characters that are represented in hexadecimal format, (ampersand)#xhhhh;, with the corresponding characters

          • Replaces characters that are represented in decimal format, (ampersand)#nnnn;, with the corresponding characters

          LOWERCASE

          Use this option to convert uppercase letters (A-Z) to lowercase (a-z).

          URL_DECODE

          Use this option to decode a URL-encoded value.

          NONE

          Specify NONE if you don't want to perform any text transformations.

          Possible values include:
          • "NONE"
          • "COMPRESS_WHITE_SPACE"
          • "HTML_ENTITY_DECODE"
          • "LOWERCASE"
          • "CMD_LINE"
          • "URL_DECODE"

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response) —

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error) —

      the error object returned from the request. Set to null if the request is successful.

    • data (Object) —

      the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

      • ChangeToken — (String)

        The ChangeToken that you used to submit the UpdateSqlInjectionMatchSet request. You can also use this value to query the status of the request. For more information, see GetChangeTokenStatus.

Returns:

  • (AWS.Request) —

    a handle to the operation request for subsequent event callback registration.

updateWebACL(params = {}, callback) ⇒ AWS.Request

Note: This is AWS WAF Classic documentation. For more information, see AWS WAF Classic in the developer guide. For the latest version of AWS WAF, use the AWS WAFV2 API and see the AWS WAF Developer Guide. With the latest version, AWS WAF has a single set of endpoints for regional and global use.

Inserts or deletes ActivatedRule objects in a WebACL. Each Rule identifies web requests that you want to allow, block, or count. When you update a WebACL, you specify the following values:

  • A default action for the WebACL, either ALLOW or BLOCK. AWS WAF performs the default action if a request doesn't match the criteria in any of the Rules in a WebACL.

  • The Rules that you want to add or delete. If you want to replace one Rule with another, you delete the existing Rule and add the new one.

  • For each Rule, whether you want AWS WAF to allow requests, block requests, or count requests that match the conditions in the Rule.

  • The order in which you want AWS WAF to evaluate the Rules in a WebACL. If you add more than one Rule to a WebACL, AWS WAF evaluates each request against the Rules in order based on the value of Priority. (The Rule that has the lowest value for Priority is evaluated first.) When a web request matches all the predicates (such as ByteMatchSets and IPSets) in a Rule, AWS WAF immediately takes the corresponding action, allow or block, and doesn't evaluate the request against the remaining Rules in the WebACL, if any.

To create and configure a WebACL, perform the following steps:

  1. Create and update the predicates that you want to include in Rules. For more information, see CreateByteMatchSet, UpdateByteMatchSet, CreateIPSet, UpdateIPSet, CreateSqlInjectionMatchSet, and UpdateSqlInjectionMatchSet.

  2. Create and update the Rules that you want to include in the WebACL. For more information, see CreateRule and UpdateRule.

  3. Create a WebACL. See CreateWebACL.

  4. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateWebACL request.

  5. Submit an UpdateWebACL request to specify the Rules that you want to include in the WebACL, to specify the default action, and to associate the WebACL with a CloudFront distribution.

    The ActivatedRule can be a rule group. If you specify a rule group as your ActivatedRule , you can exclude specific rules from that rule group.

    If you already have a rule group associated with a web ACL and want to submit an UpdateWebACL request to exclude certain rules from that rule group, you must first remove the rule group from the web ACL, the re-insert it again, specifying the excluded rules. For details, see ActivatedRule$ExcludedRules .

Be aware that if you try to add a RATE_BASED rule to a web ACL without setting the rule type when first creating the rule, the UpdateWebACL request will fail because the request tries to add a REGULAR rule (the default rule type) with the specified ID, which does not exist.

For more information about how to use the AWS WAF API to allow or block HTTP requests, see the AWS WAF Developer Guide.

Parameters:

  • params (Object) (defaults to: {}) —
    • WebACLId — (String)

      The WebACLId of the WebACL that you want to update. WebACLId is returned by CreateWebACL and by ListWebACLs.

    • ChangeToken — (String)

      The value returned by the most recent call to GetChangeToken.

    • Updates — (Array<map>)

      An array of updates to make to the WebACL.

      An array of WebACLUpdate objects that you want to insert into or delete from a WebACL. For more information, see the applicable data types:

      • WebACLUpdate: Contains Action and ActivatedRule

      • ActivatedRule: Contains Action, OverrideAction, Priority, RuleId, and Type. ActivatedRule|OverrideAction applies only when updating or adding a RuleGroup to a WebACL. In this case, you do not use ActivatedRule|Action. For all other update requests, ActivatedRule|Action is used instead of ActivatedRule|OverrideAction.

      • WafAction: Contains Type

      • Action — required — (String)

        Specifies whether to insert a Rule into or delete a Rule from a WebACL.

        Possible values include:
        • "INSERT"
        • "DELETE"
      • ActivatedRule — required — (map)

        The ActivatedRule object in an UpdateWebACL request specifies a Rule that you want to insert or delete, the priority of the Rule in the WebACL, and the action that you want AWS WAF to take when a web request matches the Rule (ALLOW, BLOCK, or COUNT).

        • Priority — required — (Integer)

          Specifies the order in which the Rules in a WebACL are evaluated. Rules with a lower value for Priority are evaluated before Rules with a higher value. The value must be a unique integer. If you add multiple Rules to a WebACL, the values don't need to be consecutive.

        • RuleId — required — (String)

          The RuleId for a Rule. You use RuleId to get more information about a Rule (see GetRule), update a Rule (see UpdateRule), insert a Rule into a WebACL or delete a one from a WebACL (see UpdateWebACL), or delete a Rule from AWS WAF (see DeleteRule).

          RuleId is returned by CreateRule and by ListRules.

        • Action — (map)

          Specifies the action that CloudFront or AWS WAF takes when a web request matches the conditions in the Rule. Valid values for Action include the following:

          • ALLOW: CloudFront responds with the requested object.

          • BLOCK: CloudFront responds with an HTTP 403 (Forbidden) status code.

          • COUNT: AWS WAF increments a counter of requests that match the conditions in the rule and then continues to inspect the web request based on the remaining rules in the web ACL.

          ActivatedRule|OverrideAction applies only when updating or adding a RuleGroup to a WebACL. In this case, you do not use ActivatedRule|Action. For all other update requests, ActivatedRule|Action is used instead of ActivatedRule|OverrideAction.

          • Type — required — (String)

            Specifies how you want AWS WAF to respond to requests that match the settings in a Rule. Valid settings include the following:

            • ALLOW: AWS WAF allows requests

            • BLOCK: AWS WAF blocks requests

            • COUNT: AWS WAF increments a counter of the requests that match all of the conditions in the rule. AWS WAF then continues to inspect the web request based on the remaining rules in the web ACL. You can't specify COUNT for the default action for a WebACL.

            Possible values include:
            • "BLOCK"
            • "ALLOW"
            • "COUNT"
        • OverrideAction — (map)

          Use the OverrideAction to test your RuleGroup.

          Any rule in a RuleGroup can potentially block a request. If you set the OverrideAction to None, the RuleGroup will block a request if any individual rule in the RuleGroup matches the request and is configured to block that request. However if you first want to test the RuleGroup, set the OverrideAction to Count. The RuleGroup will then override any block action specified by individual rules contained within the group. Instead of blocking matching requests, those requests will be counted. You can view a record of counted requests using GetSampledRequests.

          ActivatedRule|OverrideAction applies only when updating or adding a RuleGroup to a WebACL. In this case you do not use ActivatedRule|Action. For all other update requests, ActivatedRule|Action is used instead of ActivatedRule|OverrideAction.

          • Type — required — (String)

            COUNT overrides the action specified by the individual rule within a RuleGroup . If set to NONE, the rule's action will take place.

            Possible values include:
            • "NONE"
            • "COUNT"
        • Type — (String)

          The rule type, either REGULAR, as defined by Rule, RATE_BASED, as defined by RateBasedRule, or GROUP, as defined by RuleGroup. The default is REGULAR. Although this field is optional, be aware that if you try to add a RATE_BASED rule to a web ACL without setting the type, the UpdateWebACL request will fail because the request tries to add a REGULAR rule with the specified ID, which does not exist.

          Possible values include:
          • "REGULAR"
          • "RATE_BASED"
          • "GROUP"
        • ExcludedRules — (Array<map>)

          An array of rules to exclude from a rule group. This is applicable only when the ActivatedRule refers to a RuleGroup.

          Sometimes it is necessary to troubleshoot rule groups that are blocking traffic unexpectedly (false positives). One troubleshooting technique is to identify the specific rule within the rule group that is blocking the legitimate traffic and then disable (exclude) that particular rule. You can exclude rules from both your own rule groups and AWS Marketplace rule groups that have been associated with a web ACL.

          Specifying ExcludedRules does not remove those rules from the rule group. Rather, it changes the action for the rules to COUNT. Therefore, requests that match an ExcludedRule are counted but not blocked. The RuleGroup owner will receive COUNT metrics for each ExcludedRule.

          If you want to exclude rules from a rule group that is already associated with a web ACL, perform the following steps:

          1. Use the AWS WAF logs to identify the IDs of the rules that you want to exclude. For more information about the logs, see Logging Web ACL Traffic Information.

          2. Submit an UpdateWebACL request that has two actions:

            • The first action deletes the existing rule group from the web ACL. That is, in the UpdateWebACL request, the first Updates:Action should be DELETE and Updates:ActivatedRule:RuleId should be the rule group that contains the rules that you want to exclude.

            • The second action inserts the same rule group back in, but specifying the rules to exclude. That is, the second Updates:Action should be INSERT, Updates:ActivatedRule:RuleId should be the rule group that you just removed, and ExcludedRules should contain the rules that you want to exclude.

          • RuleId — required — (String)

            The unique identifier for the rule to exclude from the rule group.

    • DefaultAction — (map)

      A default action for the web ACL, either ALLOW or BLOCK. AWS WAF performs the default action if a request doesn't match the criteria in any of the rules in a web ACL.

      • Type — required — (String)

        Specifies how you want AWS WAF to respond to requests that match the settings in a Rule. Valid settings include the following:

        • ALLOW: AWS WAF allows requests

        • BLOCK: AWS WAF blocks requests

        • COUNT: AWS WAF increments a counter of the requests that match all of the conditions in the rule. AWS WAF then continues to inspect the web request based on the remaining rules in the web ACL. You can't specify COUNT for the default action for a WebACL.

        Possible values include:
        • "BLOCK"
        • "ALLOW"
        • "COUNT"

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response) —

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error) —

      the error object returned from the request. Set to null if the request is successful.

    • data (Object) —

      the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

      • ChangeToken — (String)

        The ChangeToken that you used to submit the UpdateWebACL request. You can also use this value to query the status of the request. For more information, see GetChangeTokenStatus.

Returns:

  • (AWS.Request) —

    a handle to the operation request for subsequent event callback registration.

updateXssMatchSet(params = {}, callback) ⇒ AWS.Request

Note: This is AWS WAF Classic documentation. For more information, see AWS WAF Classic in the developer guide. For the latest version of AWS WAF, use the AWS WAFV2 API and see the AWS WAF Developer Guide. With the latest version, AWS WAF has a single set of endpoints for regional and global use.

Inserts or deletes XssMatchTuple objects (filters) in an XssMatchSet. For each XssMatchTuple object, you specify the following values:

  • Action: Whether to insert the object into or delete the object from the array. To change an XssMatchTuple, you delete the existing object and add a new one.

  • FieldToMatch: The part of web requests that you want AWS WAF to inspect and, if you want AWS WAF to inspect a header or custom query parameter, the name of the header or parameter.

  • TextTransformation: Which text transformation, if any, to perform on the web request before inspecting the request for cross-site scripting attacks.

    You can only specify a single type of TextTransformation.

You use XssMatchSet objects to specify which CloudFront requests that you want to allow, block, or count. For example, if you're receiving requests that contain cross-site scripting attacks in the request body and you want to block the requests, you can create an XssMatchSet with the applicable settings, and then configure AWS WAF to block the requests.

To create and configure an XssMatchSet, perform the following steps:

  1. Submit a CreateXssMatchSet request.

  2. Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateIPSet request.

  3. Submit an UpdateXssMatchSet request to specify the parts of web requests that you want AWS WAF to inspect for cross-site scripting attacks.

For more information about how to use the AWS WAF API to allow or block HTTP requests, see the AWS WAF Developer Guide.

To update an XSS match set


/* The following example deletes an XssMatchTuple object (filters) in an XssMatchSet with the ID example1ds3t-46da-4fdb-b8d5-abc321j569j5. */

 var params = {
  ChangeToken: "abcd12f2-46da-4fdb-b8d5-fbd4c466928f", 
  Updates: [
     {
    Action: "DELETE", 
    XssMatchTuple: {
     FieldToMatch: {
      Type: "QUERY_STRING"
     }, 
     TextTransformation: "URL_DECODE"
    }
   }
  ], 
  XssMatchSetId: "example1ds3t-46da-4fdb-b8d5-abc321j569j5"
 };
 wafregional.updateXssMatchSet(params, function(err, data) {
   if (err) console.log(err, err.stack); // an error occurred
   else     console.log(data);           // successful response
   /*
   data = {
    ChangeToken: "abcd12f2-46da-4fdb-b8d5-fbd4c466928f"
   }
   */
 });

});

Parameters:

  • params (Object) (defaults to: {}) —
    • XssMatchSetId — (String)

      The XssMatchSetId of the XssMatchSet that you want to update. XssMatchSetId is returned by CreateXssMatchSet and by ListXssMatchSets.

    • ChangeToken — (String)

      The value returned by the most recent call to GetChangeToken.

    • Updates — (Array<map>)

      An array of XssMatchSetUpdate objects that you want to insert into or delete from an XssMatchSet. For more information, see the applicable data types:

      • Action — required — (String)

        Specify INSERT to add an XssMatchSetUpdate to an XssMatchSet. Use DELETE to remove an XssMatchSetUpdate from an XssMatchSet.

        Possible values include:
        • "INSERT"
        • "DELETE"
      • XssMatchTuple — required — (map)

        Specifies the part of a web request that you want AWS WAF to inspect for cross-site scripting attacks and, if you want AWS WAF to inspect a header, the name of the header.

        • FieldToMatch — required — (map)

          Specifies where in a web request to look for cross-site scripting attacks.

          • Type — required — (String)

            The part of the web request that you want AWS WAF to search for a specified string. Parts of a request that you can search include the following:

            • HEADER: A specified request header, for example, the value of the User-Agent or Referer header. If you choose HEADER for the type, specify the name of the header in Data.

            • METHOD: The HTTP method, which indicated the type of operation that the request is asking the origin to perform. Amazon CloudFront supports the following methods: DELETE, GET, HEAD, OPTIONS, PATCH, POST, and PUT.

            • QUERY_STRING: A query string, which is the part of a URL that appears after a ? character, if any.

            • URI: The part of a web request that identifies a resource, for example, /images/daily-ad.jpg.

            • BODY: The part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form. The request body immediately follows the request headers. Note that only the first 8192 bytes of the request body are forwarded to AWS WAF for inspection. To allow or block requests based on the length of the body, you can create a size constraint set. For more information, see CreateSizeConstraintSet.

            • SINGLE_QUERY_ARG: The parameter in the query string that you will inspect, such as UserName or SalesRegion. The maximum length for SINGLE_QUERY_ARG is 30 characters.

            • ALL_QUERY_ARGS: Similar to SINGLE_QUERY_ARG, but rather than inspecting a single parameter, AWS WAF will inspect all parameters within the query for the value or regex pattern that you specify in TargetString.

            Possible values include:
            • "URI"
            • "QUERY_STRING"
            • "HEADER"
            • "METHOD"
            • "BODY"
            • "SINGLE_QUERY_ARG"
            • "ALL_QUERY_ARGS"
          • Data — (String)

            When the value of Type is HEADER, enter the name of the header that you want AWS WAF to search, for example, User-Agent or Referer. The name of the header is not case sensitive.

            When the value of Type is SINGLE_QUERY_ARG, enter the name of the parameter that you want AWS WAF to search, for example, UserName or SalesRegion. The parameter name is not case sensitive.

            If the value of Type is any other value, omit Data.

        • TextTransformation — required — (String)

          Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass AWS WAF. If you specify a transformation, AWS WAF performs the transformation on FieldToMatch before inspecting it for a match.

          You can only specify a single type of TextTransformation.

          CMD_LINE

          When you're concerned that attackers are injecting an operating system command line command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:

          • Delete the following characters: \ " ' ^

          • Delete spaces before the following characters: / (

          • Replace the following characters with a space: , ;

          • Replace multiple spaces with one space

          • Convert uppercase letters (A-Z) to lowercase (a-z)

          COMPRESS_WHITE_SPACE

          Use this option to replace the following characters with a space character (decimal 32):

          • \f, formfeed, decimal 12

          • \t, tab, decimal 9

          • \n, newline, decimal 10

          • \r, carriage return, decimal 13

          • \v, vertical tab, decimal 11

          • non-breaking space, decimal 160

          COMPRESS_WHITE_SPACE also replaces multiple spaces with one space.

          HTML_ENTITY_DECODE

          Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE performs the following operations:

          • Replaces (ampersand)quot; with "

          • Replaces (ampersand)nbsp; with a non-breaking space, decimal 160

          • Replaces (ampersand)lt; with a "less than" symbol

          • Replaces (ampersand)gt; with >

          • Replaces characters that are represented in hexadecimal format, (ampersand)#xhhhh;, with the corresponding characters

          • Replaces characters that are represented in decimal format, (ampersand)#nnnn;, with the corresponding characters

          LOWERCASE

          Use this option to convert uppercase letters (A-Z) to lowercase (a-z).

          URL_DECODE

          Use this option to decode a URL-encoded value.

          NONE

          Specify NONE if you don't want to perform any text transformations.

          Possible values include:
          • "NONE"
          • "COMPRESS_WHITE_SPACE"
          • "HTML_ENTITY_DECODE"
          • "LOWERCASE"
          • "CMD_LINE"
          • "URL_DECODE"

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

    • (AWS.Response) —

      the response object containing error, data properties, and the original request object.

    Parameters:

    • err (Error) —

      the error object returned from the request. Set to null if the request is successful.

    • data (Object) —

      the de-serialized data returned from the request. Set to null if a request error occurs. The data object has the following properties:

      • ChangeToken — (String)

        The ChangeToken that you used to submit the UpdateXssMatchSet request. You can also use this value to query the status of the request. For more information, see GetChangeTokenStatus.

Returns:

  • (AWS.Request) —

    a handle to the operation request for subsequent event callback registration.
