account_id

Type: STRING

arn

Type: STRING
Provider name: ARN
Description: The Amazon Resource Name (ARN) of the entity.

available_labels

Type: UNORDERED_LIST_STRUCT
Provider name: AvailableLabels
Description: The labels that one or more rules in this rule group add to matching web requests. These labels are defined in the RuleLabels for a Rule.

• name
  Type: STRING
  Provider name: Name
  Description: An individual label specification.
  

capacity

Type: INT64
Provider name: Capacity
Description: The web ACL capacity units (WCUs) required for this rule group. When you create your own rule group, you define this, and you cannot change it after creation. When you add or modify the rules in a rule group, WAF enforces this limit. You can check the capacity for a set of rules using CheckCapacity. WAF uses WCUs to calculate and control the operating resources that are used to run your rules, rule groups, and web ACLs. WAF calculates capacity differently for each rule type, to reflect the relative cost of each rule. Simple rules that cost little to run use fewer WCUs than more complex rules that use more processing power. Rule group capacity is fixed at creation, which helps users plan their web ACL WCU usage when they use a rule group. For more information, see WAF web ACL capacity units (WCU) in the WAF Developer Guide.

consumed_labels

Type: UNORDERED_LIST_STRUCT
Provider name: ConsumedLabels
Description: The labels that one or more rules in this rule group match against in label match statements. These labels are defined in a LabelMatchStatement specification, in the Statement definition of a rule.

description

Type: STRING
Provider name: Description
Description: A description of the rule group that helps with identification.

id

Type: STRING
Provider name: Id
Description: A unique identifier for the rule group. This ID is returned in the responses to create and list commands. You provide it to operations like update and delete.

label_namespace

Type: STRING
Provider name: LabelNamespace
Description: The label namespace prefix for this rule group. All labels added by rules in this rule group have this prefix.

• The syntax for the label namespace prefix for your rule groups is the following: awswaf:<account ID>:rulegroup:<rule group name>:
• When a rule with a label matches a web request, WAF adds the fully qualified label to the request. A fully qualified label is made up of the label namespace from the rule group or web ACL where the rule is defined and the label from the rule, separated by a colon: <label namespace>:<label from rule>

lock_token

Type: STRING
Provider name: LockToken
Description: A token used for optimistic locking. WAF returns a token to your get and list requests, to mark the state of the entity at the time of the request. To make changes to the entity associated with the token, you provide the token to operations like update and delete. WAF uses the token to ensure that no changes have been made to the entity since you last retrieved it. If a change has been made, the update fails with a WAFOptimisticLockException. If this happens, perform another get, and use the new token returned by that operation.

name

Type: STRING
Provider name: Name
Description: The name of the rule group. You cannot change the name of a rule group after you create it.

rules

Type: UNORDERED_LIST_STRUCT

      • body
        Type: STRUCT
        Provider name: Body
        Description: Inspect the request body as plain text. The request body immediately follows the request headers. This is 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. WAF does not support inspecting the entire contents of the web request body if the body exceeds the limit for the resource type. When a web request body is larger than the limit, the underlying host service only forwards the contents that are within the limit to WAF for inspection.

        • For Application Load Balancer and AppSync, the limit is fixed at 8 KB (8,192 bytes).
        • For CloudFront, API Gateway, Amazon Cognito, App Runner, and Verified Access, the default limit is 16 KB (16,384 bytes), and you can increase the limit for each resource type in the web ACL AssociationConfig, for additional processing fees.
        For information about how to handle oversized request bodies, see the Body object configuration.
        
        • oversize_handling
          Type: STRING
          Provider name: OversizeHandling
          Description: What WAF should do if the body is larger than WAF can inspect. WAF does not support inspecting the entire contents of the web request body if the body exceeds the limit for the resource type. When a web request body is larger than the limit, the underlying host service only forwards the contents that are within the limit to WAF for inspection.
          • For Application Load Balancer and AppSync, the limit is fixed at 8 KB (8,192 bytes).
          • For CloudFront, API Gateway, Amazon Cognito, App Runner, and Verified Access, the default limit is 16 KB (16,384 bytes), and you can increase the limit for each resource type in the web ACL AssociationConfig, for additional processing fees.
          The options for oversize handling are the following:
          • CONTINUE - Inspect the available body contents normally, according to the rule inspection criteria.
          • MATCH - Treat the web request as matching the rule statement. WAF applies the rule action to the request.
          • NO_MATCH - Treat the web request as not matching the rule statement.
          You can combine the MATCH or NO_MATCH settings for oversize handling with your rule and web ACL action settings, so that you block any request whose body is over the limit.
          Default: CONTINUE

      • cookies
        Type: STRUCT
        Provider name: Cookies
        Description: Inspect the request cookies. You must configure scope and pattern matching filters in the Cookies object, to define the set of cookies and the parts of the cookies that WAF inspects. Only the first 8 KB (8192 bytes) of a request’s cookies and only the first 200 cookies are forwarded to WAF for inspection by the underlying host service.

          Provider name: MatchScope
          Description: The parts of the cookies to inspect with the rule inspection criteria. If you specify ALL, WAF inspects both keys and values. All does not require a match to be found in the keys and a match to be found in the values. It requires a match to be found in the keys or the values or both. To require a match in the keys and in the values, use a logical AND statement to combine two match rules, one that inspects the keys and another that inspects the values.
          
        • oversize_handling
          Type: STRING
          Provider name: OversizeHandling

        • match_scope
          Type: STRING
          Provider name: MatchScope
          Description: The parts of the headers to match with the rule inspection criteria. If you specify ALL, WAF inspects both keys and values. All does not require a match to be found in the keys and a match to be found in the values. It requires a match to be found in the keys or the values or both. To require a match in the keys and in the values, use a logical AND statement to combine two match rules, one that inspects the keys and another that inspects the values.
          
        • oversize_handling
          Type: STRING
          Provider name: OversizeHandling
          Description: What WAF should do if the headers of the request are more numerous or larger than WAF can inspect. WAF does not support inspecting the entire contents of request headers when they exceed 8 KB (8192 bytes) or 200 total headers. The underlying host service forwards a maximum of 200 headers and at most 8 KB of header contents to WAF. The options for oversize handling are the following:
          • CONTINUE - Inspect the available headers normally, according to the rule inspection criteria.
          • MATCH - Treat the web request as matching the rule statement. WAF applies the rule action to the request.
          • NO_MATCH - Treat the web request as not matching the rule statement.

      • ja3_fingerprint
        Type: STRUCT
        Provider name: JA3Fingerprint
        Description: Available for use with Amazon CloudFront distributions and Application Load Balancers. Match against the request’s JA3 fingerprint. The JA3 fingerprint is a 32-character hash derived from the TLS Client Hello of an incoming request. This fingerprint serves as a unique identifier for the client’s TLS configuration. WAF calculates and logs this fingerprint for each request that has enough TLS Client Hello information for the calculation. Almost all web requests include this information. You can use this choice only with a string match ByteMatchStatement with the PositionalConstraint set to EXACTLY. You can obtain the JA3 fingerprint for client requests from the web ACL logs. If WAF is able to calculate the fingerprint, it includes it in the logs. For information about the logging fields, see Log fields in the WAF Developer Guide. Provide the JA3 fingerprint string from the logs in your string match statement specification, to match with any future requests that have the same TLS configuration.
        

        • fallback_behavior
          Type: STRING
          Provider name: FallbackBehavior
          Description: The match status to assign to the web request if the request doesn’t have a JA3 fingerprint. You can specify the following fallback behaviors:
          • MATCH - Treat the web request as matching the rule statement. WAF applies the rule action to the request.
          • NO_MATCH - Treat the web request as not matching the rule statement.

      • json_body
        Type: STRUCT
        Provider name: JsonBody
        Description: Inspect the request body as JSON. The request body immediately follows the request headers. This is 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. WAF does not support inspecting the entire contents of the web request body if the body exceeds the limit for the resource type. When a web request body is larger than the limit, the underlying host service only forwards the contents that are within the limit to WAF for inspection.

        • For Application Load Balancer and AppSync, the limit is fixed at 8 KB (8,192 bytes).
        • For CloudFront, API Gateway, Amazon Cognito, App Runner, and Verified Access, the default limit is 16 KB (16,384 bytes), and you can increase the limit for each resource type in the web ACL AssociationConfig, for additional processing fees.
        For information about how to handle oversized request bodies, see the JsonBody object configuration.
        
        • invalid_fallback_behavior
          Type: STRING
          Provider name: InvalidFallbackBehavior
          Description: What WAF should do if it fails to completely parse the JSON body. The options are the following:
          • EVALUATE_AS_STRING - Inspect the body as plain text. WAF applies the text transformations and inspection criteria that you defined for the JSON inspection to the body text string.
          • MATCH - Treat the web request as matching the rule statement. WAF applies the rule action to the request.
          • NO_MATCH - Treat the web request as not matching the rule statement.
          If you don’t provide this setting, WAF parses and evaluates the content only up to the first parsing failure that it encounters. WAF parsing doesn’t fully validate the input JSON string, so parsing can succeed even for invalid JSON. When parsing succeeds, WAF doesn’t apply the fallback behavior. For more information, see JSON body in the WAF Developer Guide.
          
        • match_pattern
          Type: STRUCT
          Provider name: MatchPattern
          Description: The patterns to look for in the JSON body. WAF inspects the results of these pattern matches against the rule inspection criteria.
          

          • all
            Type: STRUCT
            Provider name: All
            Description: Match all of the elements. See also MatchScope in JsonBody. You must specify either this setting or the IncludedPaths setting, but not both.
            

          • included_paths
            Type: UNORDERED_LIST_STRING
            Provider name: IncludedPaths
            Description: Match only the specified include paths. See also MatchScope in JsonBody. Provide the include paths using JSON Pointer syntax. For example, “IncludedPaths”: ["/dogs/0/name", “/dogs/1/name”]. For information about this syntax, see the Internet Engineering Task Force (IETF) documentation JavaScript Object Notation (JSON) Pointer. You must specify either this setting or the All setting, but not both. Don’t use this option to include all paths. Instead, use the All setting.
            

        • match_scope
          Type: STRING
          Provider name: MatchScope
          Description: The parts of the JSON to match against using the MatchPattern. If you specify ALL, WAF matches against keys and values. All does not require a match to be found in the keys and a match to be found in the values. It requires a match to be found in the keys or the values or both. To require a match in the keys and in the values, use a logical AND statement to combine two match rules, one that inspects the keys and another that inspects the values.
          
        • oversize_handling
          Type: STRING
          Provider name: OversizeHandling
          Description: What WAF should do if the body is larger than WAF can inspect. WAF does not support inspecting the entire contents of the web request body if the body exceeds the limit for the resource type. When a web request body is larger than the limit, the underlying host service only forwards the contents that are within the limit to WAF for inspection.
          • For Application Load Balancer and AppSync, the limit is fixed at 8 KB (8,192 bytes).
          • For CloudFront, API Gateway, Amazon Cognito, App Runner, and Verified Access, the default limit is 16 KB (16,384 bytes), and you can increase the limit for each resource type in the web ACL AssociationConfig, for additional processing fees.
          The options for oversize handling are the following:
          • CONTINUE - Inspect the available body contents normally, according to the rule inspection criteria.
          • MATCH - Treat the web request as matching the rule statement. WAF applies the rule action to the request.
          • NO_MATCH - Treat the web request as not matching the rule statement.
          You can combine the MATCH or NO_MATCH settings for oversize handling with your rule and web ACL action settings, so that you block any request whose body is over the limit.
          Default: CONTINUE

      • method
        Type: STRUCT
        Provider name: Method
        Description: Inspect the HTTP method. The method indicates the type of operation that the request is asking the origin to perform.
        

      • query_string
        Type: STRUCT

        Description: Inspect the query string. This is the part of a URL that appears after a ? character, if any.
        

      • single_header
        Type: STRUCT
        Provider name: SingleHeader
        Description: Inspect a single header. Provide the name of the header to inspect, for example, User-Agent or Referer. This setting isn’t case sensitive. Example JSON: “SingleHeader”: { “Name”: “haystack” } Alternately, you can filter and inspect all headers with the Headers FieldToMatch setting.
        

        • name
          Type: STRING
          Provider name: Name

    • positional_constraint
      Type: STRING
      Provider name: PositionalConstraint
      Description: The area within the portion of the web request that you want WAF to search for SearchString. Valid values include the following: CONTAINS The specified part of the web request must include the value of SearchString, but the location doesn’t matter. CONTAINS_WORD The specified part of the web request must include the value of SearchString, and SearchString must contain only alphanumeric characters or underscore (A-Z, a-z, 0-9, or ). In addition, SearchString must be a word, which means that both of the following are true:
      • SearchString is at the beginning of the specified part of the web request or is preceded by a character other than an alphanumeric character or underscore (). Examples include the value of a header and ;BadBot.
      • SearchString is at the end of the specified part of the web request or is followed by a character other than an alphanumeric character or underscore (_), for example, BadBot; and -BadBot;.

STARTS_WITH The value of SearchString must appear at the beginning of the specified part of the web request. ENDS_WITH The value of SearchString must appear at the end of the specified part of the web request.
      
    • text_transformations
      Type: UNORDERED_LIST_STRUCT
      Provider name: TextTransformations
      Description: Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. Text transformations are used in rule match statements, to transform the FieldToMatch request component before inspecting it, and they’re used in rate-based rule statements, to transform request components before using them as custom aggregation keys. If you specify one or more transformations to apply, WAF performs all transformations on the specified content, starting from the lowest priority setting, and then uses the transformed component contents.
      
      • priority
        Type: INT32
        Provider name: Priority
        Description: Sets the relative processing order for multiple transformations. WAF processes all transformations, from lowest priority to highest, before inspecting the transformed content. The priorities don’t need to be consecutive, but they must all be different.
        
      • type
        Type: STRING
        Provider name: Type
        Description: For detailed descriptions of each of the transformation types, see Text transformations in the WAF Developer Guide.
        
  • geo_match_statement
    Type: STRUCT
    Provider name: GeoMatchStatement
    Description: A rule statement that labels web requests by country and region and that matches against web requests based on country code. A geo match rule labels every request that it inspects regardless of whether it finds a match.
    • To manage requests only by country, you can use this statement by itself and specify the countries that you want to match against in the CountryCodes array.
    • Otherwise, configure your geo match rule with Count action so that it only labels requests. Then, add one or more label match rules to run after the geo match rule and configure them to match against the geographic labels and handle the requests as needed.
    WAF labels requests using the alpha-2 country and region codes from the International Organization for Standardization (ISO) 3166 standard. WAF determines the codes using either the IP address in the web request origin or, if you specify it, the address in the geo match ForwardedIPConfig. If you use the web request origin, the label formats are awswaf:clientip:geo:region:<ISO country code>-<ISO region code> and awswaf:clientip:geo:country:<ISO country code>. If you use a forwarded IP address, the label formats are awswaf:forwardedip:geo:region:<ISO country code>-<ISO region code> and awswaf:forwardedip:geo:country:<ISO country code>. For additional details, see Geographic match rule statement in the WAF Developer Guide.
    
    • country_codes
      Type: UNORDERED_LIST_STRING
      Provider name: CountryCodes
      Description: An array of two-character country codes that you want to match against, for example, [ “US”, “CN” ], from the alpha-2 country ISO codes of the ISO 3166 international standard. When you use a geo match statement just for the region and country labels that it adds to requests, you still have to supply a country code for the rule to evaluate. In this case, you configure the rule to only count matching requests, but it will still generate logging and count metrics for any matches. You can reduce the logging and metrics that the rule produces by specifying a country that’s unlikely to be a source of traffic to your site.
      
    • forwarded_ip_config
      Type: STRUCT
      Provider name: ForwardedIPConfig
      Description: The configuration for inspecting IP addresses in an HTTP header that you specify, instead of using the IP address that’s reported by the web request origin. Commonly, this is the X-Forwarded-For (XFF) header, but you can specify any header name. If the specified header isn’t present in the request, WAF doesn’t apply the rule to the web request at all.
      
      • fallback_behavior
        Type: STRING
        Provider name: FallbackBehavior
        Description: The match status to assign to the web request if the request doesn’t have a valid IP address in the specified position. If the specified header isn’t present in the request, WAF doesn’t apply the rule to the web request at all. You can specify the following fallback behaviors:
        • MATCH - Treat the web request as matching the rule statement. WAF applies the rule action to the request.
        • NO_MATCH - Treat the web request as not matching the rule statement.
      • header_name
        Type: STRING
        Provider name: HeaderName
        Description: The name of the HTTP header to use for the IP address. For example, to use the X-Forwarded-For (XFF) header, set this to X-Forwarded-For. If the specified header isn’t present in the request, WAF doesn’t apply the rule to the web request at all.
        
  • ip_set_reference_statement
    Type: STRUCT
    Provider name: IPSetReferenceStatement
    Description: A rule statement used to detect web requests coming from particular IP addresses or address ranges. To use this, create an IPSet that specifies the addresses you want to detect, then use the ARN of that set in this statement. To create an IP set, see CreateIPSet. Each IP set rule statement references an IP set. You create and maintain the set independent of your rules. This allows you to use the single set in multiple rules. When you update the referenced set, WAF automatically updates all rules that reference it.
    
    • arn
      Type: STRING
      Provider name: ARN
      Description: The Amazon Resource Name (ARN) of the IPSet that this statement references.

      Description: The configuration for inspecting IP addresses in an HTTP header that you specify, instead of using the IP address that’s reported by the web request origin. Commonly, this is the X-Forwarded-For (XFF) header, but you can specify any header name. If the specified header isn’t present in the request, WAF doesn’t apply the rule to the web request at all.
      
      • fallback_behavior
        Type: STRING
        Provider name: FallbackBehavior
        Description: The match status to assign to the web request if the request doesn’t have a valid IP address in the specified position. If the specified header isn’t present in the request, WAF doesn’t apply the rule to the web request at all. You can specify the following fallback behaviors:
        • MATCH - Treat the web request as matching the rule statement. WAF applies the rule action to the request.
        • NO_MATCH - Treat the web request as not matching the rule statement.
      • header_name
        Type: STRING
        Provider name: HeaderName
        Description: The name of the HTTP header to use for the IP address. For example, to use the X-Forwarded-For (XFF) header, set this to X-Forwarded-For. If the specified header isn’t present in the request, WAF doesn’t apply the rule to the web request at all.
        
      • position
        Type: STRING
        Provider name: Position
        Description: The position in the header to search for the IP address. The header can contain IP addresses of the original client and also of proxies. For example, the header value could be 10.1.1.1, 127.0.0.0, 10.10.10.10 where the first IP address identifies the original client and the rest identify proxies that the request went through. The options for this setting are the following:
        • FIRST - Inspect the first IP address in the list of IP addresses in the header. This is usually the client’s original IP.
        • LAST - Inspect the last IP address in the list of IP addresses in the header.
        • ANY - Inspect all IP addresses in the header for a match. If the header contains more than 10 IP addresses, WAF inspects the last 10.
  • label_match_statement
    Type: STRUCT
    Provider name: LabelMatchStatement
    Description: A rule statement to match against labels that have been added to the web request by rules that have already run in the web ACL. The label match statement provides the label or namespace string to search for. The label string can represent a part or all of the fully qualified label name that had been added to the web request. Fully qualified labels have a prefix, optional namespaces, and label name. The prefix identifies the rule group or web ACL context of the rule that added the label. If you do not provide the fully qualified name in your label match string, WAF performs the search for labels that were added in the same context as the label match statement.
    
    • key
      Type: STRING
      Provider name: Key
      Description: The string to match against. The setting you provide for this depends on the match statement’s Scope setting:
      • If the Scope indicates LABEL, then this specification must include the name and can include any number of preceding namespace specifications and prefix up to providing the fully qualified label name.
      • If the Scope indicates NAMESPACE, then this specification can include any number of contiguous namespace strings, and can include the entire label namespace prefix from the rule group or web ACL where the label originates.
      Labels are case sensitive and components of a label must be separated by colon, for example NS1:NS2:name.
      
    • scope
      Type: STRING
      Provider name: Scope
      Description: Specify whether you want to match using the label name or just the namespace.
      
  • managed_rule_group_statement
    Type: STRUCT
    Provider name: ManagedRuleGroupStatement
    Description: A rule statement used to run the rules that are defined in a managed rule group. To use this, provide the vendor name and the name of the rule group in this statement. You can retrieve the required names by calling ListAvailableManagedRuleGroups. You cannot nest a ManagedRuleGroupStatement, for example for use inside a NotStatement or OrStatement. You cannot use a managed rule group inside another rule group. You can only reference a managed rule group as a top-level statement within a rule that you define in a web ACL. You are charged additional fees when you use the WAF Bot Control managed rule group AWSManagedRulesBotControlRuleSet, the WAF Fraud Control account takeover prevention (ATP) managed rule group AWSManagedRulesATPRuleSet, or the WAF Fraud Control account creation fraud prevention (ACFP) managed rule group AWSManagedRulesACFPRuleSet. For more information, see WAF Pricing.
    
    • excluded_rules
      Type: UNORDERED_LIST_STRUCT
      Provider name: ExcludedRules

      Type: UNORDERED_LIST_STRUCT
      Provider name: ManagedRuleGroupConfigs
      Description: Additional information that’s used by a managed rule group. Many managed rule groups don’t require this. The rule groups used for intelligent threat mitigation require additional configuration:
      • Use the AWSManagedRulesACFPRuleSet configuration object to configure the account creation fraud prevention managed rule group. The configuration includes the registration and sign-up pages of your application and the locations in the account creation request payload of data, such as the user email and phone number fields.
      • Use the AWSManagedRulesATPRuleSet configuration object to configure the account takeover prevention managed rule group. The configuration includes the sign-in page of your application and the locations in the login request payload of data such as the username and password.
      • Use the AWSManagedRulesBotControlRuleSet configuration object to configure the protection level that you want the Bot Control rule group to use.
      • aws_managed_rules_acfp_rule_set
        Type: STRUCT
        Provider name: AWSManagedRulesACFPRuleSet
        Description: Additional configuration for using the account creation fraud prevention (ACFP) managed rule group, AWSManagedRulesACFPRuleSet. Use this to provide account creation request information to the rule group. For web ACLs that protect CloudFront distributions, use this to also provide the information about how your distribution responds to account creation requests. For information about using the ACFP managed rule group, see WAF Fraud Control account creation fraud prevention (ACFP) rule group and WAF Fraud Control account creation fraud prevention (ACFP) in the WAF Developer Guide.

        Description: Inspect the request body as plain text. The request body immediately follows the request headers. This is 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. WAF does not support inspecting the entire contents of the web request body if the body exceeds the limit for the resource type. When a web request body is larger than the limit, the underlying host service only forwards the contents that are within the limit to WAF for inspection.

        • For Application Load Balancer and AppSync, the limit is fixed at 8 KB (8,192 bytes).
        • For CloudFront, API Gateway, Amazon Cognito, App Runner, and Verified Access, the default limit is 16 KB (16,384 bytes), and you can increase the limit for each resource type in the web ACL AssociationConfig, for additional processing fees.
        For information about how to handle oversized request bodies, see the Body object configuration.

          • For Application Load Balancer and AppSync, the limit is fixed at 8 KB (8,192 bytes).
          • For CloudFront, API Gateway, Amazon Cognito, App Runner, and Verified Access, the default limit is 16 KB (16,384 bytes), and you can increase the limit for each resource type in the web ACL AssociationConfig, for additional processing fees.
          The options for oversize handling are the following:
          • CONTINUE - Inspect the available body contents normally, according to the rule inspection criteria.
          • MATCH - Treat the web request as matching the rule statement. WAF applies the rule action to the request.
          • NO_MATCH - Treat the web request as not matching the rule statement.
          You can combine the MATCH or NO_MATCH settings for oversize handling with your rule and web ACL action settings, so that you block any request whose body is over the limit.

      • ja3_fingerprint
        Type: STRUCT
        Provider name: JA3Fingerprint
        Description: Available for use with Amazon CloudFront distributions and Application Load Balancers. Match against the request’s JA3 fingerprint. The JA3 fingerprint is a 32-character hash derived from the TLS Client Hello of an incoming request. This fingerprint serves as a unique identifier for the client’s TLS configuration. WAF calculates and logs this fingerprint for each request that has enough TLS Client Hello information for the calculation. Almost all web requests include this information. You can use this choice only with a string match ByteMatchStatement with the PositionalConstraint set to EXACTLY. You can obtain the JA3 fingerprint for client requests from the web ACL logs. If WAF is able to calculate the fingerprint, it includes it in the logs. For information about the logging fields, see Log fields in the WAF Developer Guide. Provide the JA3 fingerprint string from the logs in your string match statement specification, to match with any future requests that have the same TLS configuration.
        

        • fallback_behavior
          Type: STRING
          Provider name: FallbackBehavior

      • json_body
        Type: STRUCT
        Provider name: JsonBody
        Description: Inspect the request body as JSON. The request body immediately follows the request headers. This is 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. WAF does not support inspecting the entire contents of the web request body if the body exceeds the limit for the resource type. When a web request body is larger than the limit, the underlying host service only forwards the contents that are within the limit to WAF for inspection.

        • For Application Load Balancer and AppSync, the limit is fixed at 8 KB (8,192 bytes).
        • For CloudFront, API Gateway, Amazon Cognito, App Runner, and Verified Access, the default limit is 16 KB (16,384 bytes), and you can increase the limit for each resource type in the web ACL AssociationConfig, for additional processing fees.
        For information about how to handle oversized request bodies, see the JsonBody object configuration.
        
        • invalid_fallback_behavior
          Type: STRING
          Provider name: InvalidFallbackBehavior
          Description: What WAF should do if it fails to completely parse the JSON body. The options are the following:
          • EVALUATE_AS_STRING - Inspect the body as plain text. WAF applies the text transformations and inspection criteria that you defined for the JSON inspection to the body text string.
          • MATCH - Treat the web request as matching the rule statement. WAF applies the rule action to the request.
          • NO_MATCH - Treat the web request as not matching the rule statement.
          If you don’t provide this setting, WAF parses and evaluates the content only up to the first parsing failure that it encounters. WAF parsing doesn’t fully validate the input JSON string, so parsing can succeed even for invalid JSON. When parsing succeeds, WAF doesn’t apply the fallback behavior. For more information, see JSON body in the WAF Developer Guide.

      Type: UNORDERED_LIST_STRUCT
      Provider name: TextTransformations
      Description: Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. Text transformations are used in rule match statements, to transform the FieldToMatch request component before inspecting it, and they’re used in rate-based rule statements, to transform request components before using them as custom aggregation keys. If you specify one or more transformations to apply, WAF performs all transformations on the specified content, starting from the lowest priority setting, and then uses the transformed component contents.
      
      • priority
        Type: INT32
        Provider name: Priority
        Description: Sets the relative processing order for multiple transformations. WAF processes all transformations, from lowest priority to highest, before inspecting the transformed content. The priorities don’t need to be consecutive, but they must all be different.

WAF does not support inspecting the entire contents of the web request body if the body exceeds the limit for the resource type. When a web request body is larger than the limit, the underlying host service only forwards the contents that are within the limit to WAF for inspection.
          • For Application Load Balancer and AppSync, the limit is fixed at 8 KB (8,192 bytes).
          • For CloudFront, API Gateway, Amazon Cognito, App Runner, and Verified Access, the default limit is 16 KB (16,384 bytes), and you can increase the limit for each resource type in the web ACL AssociationConfig, for additional processing fees.
          The options for oversize handling are the following:
          • CONTINUE - Inspect the available body contents normally, according to the rule inspection criteria.
          • MATCH - Treat the web request as matching the rule statement. WAF applies the rule action to the request.
          • NO_MATCH - Treat the web request as not matching the rule statement.
          You can combine the MATCH or NO_MATCH settings for oversize handling with your rule and web ACL action settings, so that you block any request whose body is over the limit.
          Default: CONTINUE

    Description: A rule statement that compares a number of bytes against the size of a request component, using a comparison operator, such as greater than (>) or less than (<). For example, you can use a size constraint statement to look for query strings that are longer than 100 bytes. If you configure WAF to inspect the request body, WAF inspects only the number of bytes in the body up to the limit for the web ACL and protected resource type. If you know that the request body for your web requests should never exceed the inspection limit, you can use a size constraint statement to block requests that have a larger request body size. For more information about the inspection limits, see Body and JsonBody settings for the FieldToMatch data type. If you choose URI for the value of Part of the request to filter on, the slash (/) in the URI counts as one character. For example, the URI /logo.jpg is nine characters long.

This is 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. WAF does not support inspecting the entire contents of the web request body if the body exceeds the limit for the resource type. When a web request body is larger than the limit, the underlying host service only forwards the contents that are within the limit to WAF for inspection.

        • For Application Load Balancer and AppSync, the limit is fixed at 8 KB (8,192 bytes).
        • For CloudFront, API Gateway, Amazon Cognito, App Runner, and Verified Access, the default limit is 16 KB (16,384 bytes), and you can increase the limit for each resource type in the web ACL AssociationConfig, for additional processing fees.
        For information about how to handle oversized request bodies, see the Body object configuration.

          Provider name: MatchScope
          Description: The parts of the headers to match with the rule inspection criteria. If you specify ALL, WAF inspects both keys and values. All does not require a match to be found in the keys and a match to be found in the values. It requires a match to be found in the keys or the values or both. To require a match in the keys and in the values, use a logical AND statement to combine two match rules, one that inspects the keys and another that inspects the values.
          
        • oversize_handling
          Type: STRING
          Provider name: OversizeHandling
          Description: What WAF should do if the headers of the request are more numerous or larger than WAF can inspect. WAF does not support inspecting the entire contents of request headers when they exceed 8 KB (8192 bytes) or 200 total headers. The underlying host service forwards a maximum of 200 headers and at most 8 KB of header contents to WAF. The options for oversize handling are the following:
          • CONTINUE - Inspect the available headers normally, according to the rule inspection criteria.
          • MATCH - Treat the web request as matching the rule statement. WAF applies the rule action to the request.
          • NO_MATCH - Treat the web request as not matching the rule statement.

      • ja3_fingerprint
        Type: STRUCT
        Provider name: JA3Fingerprint
        Description: Available for use with Amazon CloudFront distributions and Application Load Balancers. Match against the request’s JA3 fingerprint. The JA3 fingerprint is a 32-character hash derived from the TLS Client Hello of an incoming request. This fingerprint serves as a unique identifier for the client’s TLS configuration. WAF calculates and logs this fingerprint for each request that has enough TLS Client Hello information for the calculation. Almost all web requests include this information. You can use this choice only with a string match ByteMatchStatement with the PositionalConstraint set to EXACTLY. You can obtain the JA3 fingerprint for client requests from the web ACL logs. If WAF is able to calculate the fingerprint, it includes it in the logs. For information about the logging fields, see Log fields in the WAF Developer Guide. Provide the JA3 fingerprint string from the logs in your string match statement specification, to match with any future requests that have the same TLS configuration.
        

        • fallback_behavior
          Type: STRING
          Provider name: FallbackBehavior

          • NO_MATCH - Treat the web request as not matching the rule statement.

      • json_body
        Type: STRUCT
        Provider name: JsonBody
        Description: Inspect the request body as JSON. The request body immediately follows the request headers. This is 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. WAF does not support inspecting the entire contents of the web request body if the body exceeds the limit for the resource type. When a web request body is larger than the limit, the underlying host service only forwards the contents that are within the limit to WAF for inspection.

        • For Application Load Balancer and AppSync, the limit is fixed at 8 KB (8,192 bytes).
        • For CloudFront, API Gateway, Amazon Cognito, App Runner, and Verified Access, the default limit is 16 KB (16,384 bytes), and you can increase the limit for each resource type in the web ACL AssociationConfig, for additional processing fees.
        For information about how to handle oversized request bodies, see the JsonBody object configuration.
        
        • invalid_fallback_behavior
          Type: STRING
          Provider name: InvalidFallbackBehavior
          Description: What WAF should do if it fails to completely parse the JSON body. The options are the following:
          • EVALUATE_AS_STRING - Inspect the body as plain text. WAF applies the text transformations and inspection criteria that you defined for the JSON inspection to the body text string.
          • MATCH - Treat the web request as matching the rule statement. WAF applies the rule action to the request.
          • NO_MATCH - Treat the web request as not matching the rule statement.
          If you don’t provide this setting, WAF parses and evaluates the content only up to the first parsing failure that it encounters. WAF parsing doesn’t fully validate the input JSON string, so parsing can succeed even for invalid JSON. When parsing succeeds, WAF doesn’t apply the fallback behavior. For more information, see JSON body in the WAF Developer Guide.
          
        • match_pattern
          Type: STRUCT

For example, “IncludedPaths”: ["/dogs/0/name", “/dogs/1/name”]. For information about this syntax, see the Internet Engineering Task Force (IETF) documentation JavaScript Object Notation (JSON) Pointer. You must specify either this setting or the All setting, but not both. Don’t use this option to include all paths. Instead, use the All setting.
            

        • match_scope
          Type: STRING
          Provider name: MatchScope
          Description: The parts of the JSON to match against using the MatchPattern. If you specify ALL, WAF matches against keys and values. All does not require a match to be found in the keys and a match to be found in the values. It requires a match to be found in the keys or the values or both. To require a match in the keys and in the values, use a logical AND statement to combine two match rules, one that inspects the keys and another that inspects the values.

When a web request body is larger than the limit, the underlying host service only forwards the contents that are within the limit to WAF for inspection.
          • For Application Load Balancer and AppSync, the limit is fixed at 8 KB (8,192 bytes).
          • For CloudFront, API Gateway, Amazon Cognito, App Runner, and Verified Access, the default limit is 16 KB (16,384 bytes), and you can increase the limit for each resource type in the web ACL AssociationConfig, for additional processing fees.
          The options for oversize handling are the following:
          • CONTINUE - Inspect the available body contents normally, according to the rule inspection criteria.
          • MATCH - Treat the web request as matching the rule statement. WAF applies the rule action to the request.
          • NO_MATCH - Treat the web request as not matching the rule statement.
          You can combine the MATCH or NO_MATCH settings for oversize handling with your rule and web ACL action settings, so that you block any request whose body is over the limit.
          Default: CONTINUE

      Provider name: TextTransformations
      Description: Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection. Text transformations are used in rule match statements, to transform the FieldToMatch request component before inspecting it, and they’re used in rate-based rule statements, to transform request components before using them as custom aggregation keys. If you specify one or more transformations to apply, WAF performs all transformations on the specified content, starting from the lowest priority setting, and then uses the transformed component contents.

          Type: STRING
          Provider name: OversizeHandling
          Description: What WAF should do if the body is larger than WAF can inspect. WAF does not support inspecting the entire contents of the web request body if the body exceeds the limit for the resource type. When a web request body is larger than the limit, the underlying host service only forwards the contents that are within the limit to WAF for inspection.
          • For Application Load Balancer and AppSync, the limit is fixed at 8 KB (8,192 bytes).
          • For CloudFront, API Gateway, Amazon Cognito, App Runner, and Verified Access, the default limit is 16 KB (16,384 bytes), and you can increase the limit for each resource type in the web ACL AssociationConfig, for additional processing fees.
          The options for oversize handling are the following:
          • CONTINUE - Inspect the available body contents normally, according to the rule inspection criteria.
          • MATCH - Treat the web request as matching the rule statement. WAF applies the rule action to the request.
          • NO_MATCH - Treat the web request as not matching the rule statement.
          You can combine the MATCH or NO_MATCH settings for oversize handling with your rule and web ACL action settings, so that you block any request whose body is over the limit.

        Description: Available for use with Amazon CloudFront distributions and Application Load Balancers. Match against the request’s JA3 fingerprint. The JA3 fingerprint is a 32-character hash derived from the TLS Client Hello of an incoming request. This fingerprint serves as a unique identifier for the client’s TLS configuration. WAF calculates and logs this fingerprint for each request that has enough TLS Client Hello information for the calculation. Almost all web requests include this information. You can use this choice only with a string match ByteMatchStatement with the PositionalConstraint set to EXACTLY. You can obtain the JA3 fingerprint for client requests from the web ACL logs. If WAF is able to calculate the fingerprint, it includes it in the logs. For information about the logging fields, see Log fields in the WAF Developer Guide. Provide the JA3 fingerprint string from the logs in your string match statement specification, to match with any future requests that have the same TLS configuration.

  • cloud_watch_metrics_enabled
    Type: BOOLEAN
    Provider name: CloudWatchMetricsEnabled
    Description: Indicates whether the associated resource sends metrics to Amazon CloudWatch. For the list of available metrics, see WAF Metrics in the WAF Developer Guide. For web ACLs, the metrics are for web requests that have the web ACL default action applied. WAF applies the default action to web requests that pass the inspection of all rules in the web ACL without being either allowed or blocked. For more information, see The web ACL default action in the WAF Developer Guide.
    
  • metric_name
    Type: STRING
    Provider name: MetricName
    Description: A name of the Amazon CloudWatch metric dimension. The name can contain only the characters: A-Z, a-z, 0-9, - (hyphen), and _ (underscore). The name can be from one to 128 characters long. It can’t contain whitespace or metric names that are reserved for WAF, for example All and Default_Action.
    
  • sampled_requests_enabled
    Type: BOOLEAN
    Provider name: SampledRequestsEnabled
    Description: Indicates whether WAF should store a sampling of the web requests that match the rules. You can view the sampled requests through the WAF console. Request sampling doesn’t provide a field redaction option, and any field redaction that you specify in your logging configuration doesn’t affect sampling. The only way to exclude fields from request sampling is by disabling sampling in the web ACL visibility configuration.
