Defined in:
(unknown)

Overview

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

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();

Constructing a WAFRegional object

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

Options Hash (options):

  • params (map)

    An optional map of parameters to bind to every request sent by this service object. For more information on bound parameters, see "Working with Services" in the Getting Started Guide.

  • endpoint (String)

    The endpoint URI to send requests to. The default endpoint is built from the configured region. The endpoint should be a string like 'https://{service}.{region}.amazonaws.com'.

    your AWS secret access key.

  • sessionToken (AWS.Credentials)

    the optional AWS session token to sign requests with.

  • credentials (AWS.Credentials)

    the AWS credentials to sign requests with. You can either specify this object, or specify the accessKeyId and secretAccessKey options directly.

  • credentialProvider (AWS.CredentialProviderChain)

    the provider chain used to resolve credentials if no static credentials property is set.

  • region (String)

    the region to send service requests to. See AWS.WAFRegional.region for more information.

  • sslEnabled (Boolean)

    whether to enable SSL for requests.

  • paramValidation (Boolean|map)

    whether input parameters should be validated against the operation description before sending the request. Defaults to true. Pass a map to enable any of the following specific validation features:

    • min [Boolean] — Validates that a value meets the min constraint. This is enabled by default when paramValidation is set to true.
    • max [Boolean] — Validates that a value meets the max constraint.
    • pattern [Boolean] — Validates that a string value matches a regular expression.
    • enum [Boolean] — Validates that a string value matches one of the allowable enum values.
  • computeChecksums (Boolean)

    whether to compute checksums for payload bodies when the service accepts it (currently supported in S3 only)

  • convertResponseTypes (Boolean)

    whether types are converted when parsing response data. Currently only supported for JSON based services. Turning this off may improve performance on large response payloads. Defaults to true.

  • correctClockSkew (Boolean)

    whether to apply a clock skew correction and retry requests that fail because of an skewed client clock. Defaults to false.

  • s3ForcePathStyle (Boolean)

    whether to force path style URLs for S3 objects.

  • s3BucketEndpoint (Boolean)

    whether the provided endpoint addresses an individual bucket (false if it addresses the root API endpoint). Note that setting this configuration option requires an endpoint to be provided explicitly to the service constructor.

  • s3DisableBodySigning (Boolean)

    whether S3 body signing should be disabled when using signature version v4. Body signing can only be disabled when using https. Defaults to true.

  • retryDelayOptions (map)

    A set of options to configure the retry delay on retryable errors. Currently supported options are:

Associates a web ACL with a resource.

Service Reference:

Examples:

Calling the associateWebACL operation

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

Parameters:

    • WebACLId — (String)

      A unique identifier (ID) for the web ACL.

    • ResourceArn — (String)

      The ARN (Amazon Resource Name) of the resource to be protected.

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.

Returns:

  • (AWS.Request)

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

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

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.

        A ByteMatchSet that contains no ByteMatchTuple objects.

        • ByteMatchSetIdrequired — (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.

        • ByteMatchTuplesrequired — (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.

          • FieldToMatchrequired — (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.

            • Typerequired — (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.

              Possible values include:
              • "URI"
              • "QUERY_STRING"
              • "HEADER"
              • "METHOD"
              • "BODY"
            • 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. If the value of Type is any other value, omit Data.

              The name of the header is not case sensitive.

          • TargetStringrequired — (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.

            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.

          • TextTransformationrequired — (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 TargetString before inspecting a request for a match.

            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"
          • PositionalConstraintrequired — (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.

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

Creates an IPSet, which you use to specify which web requests 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.

            • 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.

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

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 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.

Returns:

  • (AWS.Request)

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

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

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.

          • FieldToMatchrequired — (map)

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

            • Typerequired — (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.

              Possible values include:
              • "URI"
              • "QUERY_STRING"
              • "HEADER"
              • "METHOD"
              • "BODY"
            • 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. If the value of Type is any other value, omit Data.

              The name of the header is not case sensitive.

          • TextTransformationrequired — (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 a request for a match.

            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"
          • ComparisonOperatorrequired — (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"
          • Sizerequired — (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.

Returns:

  • (AWS.Request)

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

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

Creates a SqlInjectionMatchSet, which you use to allow, block, or count requests that contain snippets of SQL code in a specified part of web requests. AWS WAF searches for character sequences that are likely to be malicious strings.

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

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

  2. Submit a CreateSqlInjectionMatchSet request.

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

  4. Submit an UpdateSqlInjectionMatchSet request to specify the parts of web requests in which you want to allow, block, or count malicious 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.

              • "URI"
              • "QUERY_STRING"
              • "HEADER"
              • "METHOD"
              • "BODY"
            • 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. If the value of Type is any other value, omit Data.

              The name of the header is not case sensitive.

          • TextTransformationrequired — (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 a request for a match.

            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

            • "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

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.

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

        • FieldToMatch: Contains Data and Type

        • ByteMatchSetIdrequired — (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.

        • ByteMatchTuplesrequired — (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.

          • FieldToMatchrequired — (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.

            • Typerequired — (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.

              Possible values include:
              • "URI"
              • "QUERY_STRING"
              • "HEADER"
              • "METHOD"
              • "BODY"
            • 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. If the value of Type is any other value, omit Data.

              The name of the header is not case sensitive.

          • TargetStringrequired — (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.

            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.

          • TextTransformationrequired — (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 TargetString before inspecting a request for a match.

            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"
          • PositionalConstraintrequired — (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"

Returns:

  • (AWS.Request)

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

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

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"
   }
   */
 });

});

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.

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

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.

    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:

      • SampledRequests — (Array<map>)

        A complex type that contains detailed information about each of the requests in the sample.

        • Requestrequired — (map)

          A complex type that contains detailed information about the request.

          • ClientIP — (String)

            The IP address that the request originated from. If the WebACL is associated with a CloudFront distribution, this is the value of one of the following fields in CloudFront access logs:

            • c-ip, if the viewer did not use an HTTP proxy or a load balancer to send the request

            • x-forwarded-for, if the viewer did use an HTTP proxy or a load balancer to send the request

          • Country — (String)

            The two-letter country code for the country that the request originated from. For a current list of country codes, see the Wikipedia entry ISO 3166-1 alpha-2.

          • URI — (String)

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

          • Method — (String)

            The HTTP method specified in the sampled web request. CloudFront supports the following methods: DELETE, GET, HEAD, OPTIONS, PATCH, POST, and PUT.

          • HTTPVersion — (String)

            The HTTP version specified in the sampled web request, for example, HTTP/1.1.

          • Headers — (Array<map>)

            A complex type that contains two values for each header in the sampled web request: the name of the header and the value of the header.

            • Name — (String)

              The name of one of the headers in the sampled web request.

            • Value — (String)

              The value of one of the headers in the sampled web request.

        • Weightrequired — (Integer)

          A value that indicates how one result in the response relates proportionally to other results in the response. A result that has a weight of 2 represents roughly twice as many CloudFront web requests as a result that has a weight of 1.

        • Timestamp — (Date)

          The time at which AWS WAF received the request from your AWS resource, in Unix time format (in seconds).

        • Action — (String)

          The action for the Rule that the request matched: ALLOW, BLOCK, or COUNT.

      • PopulationSize — (Integer)

        The total number of requests from which GetSampledRequests got a sample of MaxItems requests. If PopulationSize is less than MaxItems, the sample includes every request that your AWS resource received during the specified time range.

      • TimeWindow — (map)

        Usually, TimeWindow is the time range that you specified in the GetSampledRequests request. However, if your AWS resource received more than 5,000 requests during the time range that you specified in the request, GetSampledRequests returns the time range for the first 5,000 requests.

        • StartTimerequired — (Date)

          The beginning of the time range from which you want GetSampledRequests to return a sample of the requests that your AWS resource received. Specify the date and time in the following format: "2016-09-27T14:50Z". You can specify any time range in the previous three hours.

        • EndTimerequired — (Date)

          The end of the time range from which you want GetSampledRequests to return a sample of the requests that your AWS resource received. Specify the date and time in the following format: "2016-09-27T14:50Z". You can specify any time range in the previous three hours.

    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)

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

        • SizeConstraintSetIdrequired — (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.

        • SizeConstraintsrequired — (Array<map>)

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

          • FieldToMatchrequired — (map)

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

            • Typerequired — (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.

              Possible values include:
              • "URI"
              • "QUERY_STRING"
              • "HEADER"
              • "METHOD"
              • "BODY"
            • 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. If the value of Type is any other value, omit Data.

              The name of the header is not case sensitive.

          • TextTransformationrequired — (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 a request for a match.

            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"
          • ComparisonOperatorrequired — (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"
          • Sizerequired — (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.

          • FieldToMatchrequired — (map)

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

            • Typerequired — (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.

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

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

              The name of the header is not case sensitive.

          • TextTransformationrequired — (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 a request for a match.

            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"

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

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.

      The ByteMatchSetId of the ByteMatchSet that you want to update. ByteMatchSetId is returned by CreateByteMatchSet and by ListByteMatchSets.

    • ChangeToken — (String)

      The value returned by the most recent call to GetChangeToken.

    • Updates — (Array<map>)

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

      • Actionrequired — (String)

        Specifies whether to insert or delete a ByteMatchTuple.

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

        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.

        • FieldToMatchrequired — (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.

          • Typerequired — (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.

            Possible values include:
            • "URI"
            • "QUERY_STRING"
            • "HEADER"
            • "METHOD"
            • "BODY"
          • 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. If the value of Type is any other value, omit Data.

            The name of the header is not case sensitive.

        • TargetStringrequired — (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.

          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.

        • TextTransformationrequired — (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 TargetString before inspecting a request for a match.

          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"
        • PositionalConstraintrequired — (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.

    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.

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

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 /8, /16, /24, and /32 IP address ranges for IPv4, and /24, /32, /48, /56, /64 and /128 for IPv6. 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.

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

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.

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

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 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.

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

  • 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:

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

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

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.

  • 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.

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:

      • Actionrequired — (String)

        Specify INSERT to add a SizeConstraintSetUpdate to a SizeConstraintSet. Use DELETE to remove a SizeConstraintSetUpdate from a SizeConstraintSet.

        Possible values include:
        • "INSERT"
        • "DELETE"
      • SizeConstraintrequired — (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.

        • FieldToMatchrequired — (map)

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

          • Typerequired — (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.

            Possible values include:
            • "URI"
            • "QUERY_STRING"
            • "HEADER"
            • "METHOD"
            • "BODY"
          • 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. If the value of Type is any other value, omit Data.

            The name of the header is not case sensitive.

        • TextTransformationrequired — (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 a request for a match.

          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"
        • ComparisonOperatorrequired — (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"
        • Sizerequired — (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.

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 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

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, the name of the header.

  • TextTransformation: Which text transformation, if any, to perform on the web request before inspecting the request for snippets of malicious SQL code.

You use SqlInjectionMatchSet objects to specify which CloudFront requests 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.

});

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:

      • Actionrequired — (String)

        Specify INSERT to add a SqlInjectionMatchSetUpdate to a SqlInjectionMatchSet. Use DELETE to remove a SqlInjectionMatchSetUpdate from a SqlInjectionMatchSet.

        Possible values include:
        • "INSERT"
        • "DELETE"
      • SqlInjectionMatchTuplerequired — (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.

        • FieldToMatchrequired — (map)

          Specifies where in a web request to look for snippets of malicious SQL code.

          • Typerequired — (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.

            Possible values include:
            • "URI"
            • "QUERY_STRING"
            • "HEADER"
            • "METHOD"
            • "BODY"
          • 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. If the value of Type is any other value, omit Data.

            The name of the header is not case sensitive.

        • TextTransformationrequired — (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 a request for a match.

          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.

          • "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

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 and/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 of 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.

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

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

            The name of the header is not case sensitive.

        • TextTransformationrequired — (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 a request for a match.

          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"

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.
