    • geoMatchStatement

      @Stability(Stable) public CfnWebACL.StatementProperty.Builder geoMatchStatement(IResolvable geoMatchStatement)
      Sets the value of CfnWebACL.StatementProperty.getGeoMatchStatement()
      Parameters:
      geoMatchStatement - 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.

      AWS WAF labels requests using the alpha-2 country and region codes from the International Organization for Standardization (ISO) 3166 standard. AWS 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 AWS WAF Developer Guide .

      Returns:
      this

    • ipSetReferenceStatement

      @Stability(Stable) public CfnWebACL.StatementProperty.Builder ipSetReferenceStatement(IResolvable ipSetReferenceStatement)
      Sets the value of CfnWebACL.StatementProperty.getIpSetReferenceStatement()
      Parameters:
      ipSetReferenceStatement - 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.

      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, AWS WAF automatically updates all rules that reference it.

      Returns:

      @Stability(Stable) public CfnWebACL.StatementProperty.Builder labelMatchStatement(IResolvable labelMatchStatement)
      Sets the value of CfnWebACL.StatementProperty.getLabelMatchStatement()
      Parameters:
      labelMatchStatement - 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, AWS WAF performs the search for labels that were added in the same context as the label match statement.
      Returns:
      this

    • rateBasedStatement

      @Stability(Stable) public CfnWebACL.StatementProperty.Builder rateBasedStatement(IResolvable rateBasedStatement)
      Sets the value of CfnWebACL.StatementProperty.getRateBasedStatement()
      Parameters:
      rateBasedStatement - A rate-based rule tracks the rate of requests for each originating IP address, and triggers the rule action when the rate exceeds a limit that you specify on the number of requests in any 5-minute time span. You can use this to put a temporary block on requests from an IP address that is sending excessive requests.

      AWS WAF tracks and manages web requests separately for each instance of a rate-based rule that you use. For example, if you provide the same rate-based rule settings in two web ACLs, each of the two rule statements represents a separate instance of the rate-based rule and gets its own tracking and management by AWS WAF . If you define a rate-based rule inside a rule group, and then use that rule group in multiple places, each use creates a separate instance of the rate-based rule that gets its own tracking and management by AWS WAF .

      When the rule action triggers, AWS WAF blocks additional requests from the IP address until the request rate falls below the limit.

      You can optionally nest another statement inside the rate-based statement, to narrow the scope of the rule so that it only counts requests that match the nested statement. For example, based on recent requests that you have seen from an attacker, you might create a rate-based rule with a nested AND rule statement that contains the following nested statements:

      • An IP match statement with an IP set that specifies the address 192.0.2.44.
      • A string match statement that searches in the User-Agent header for the string BadBot.

      In this rate-based rule, you also define a rate limit. For this example, the rate limit is 1,000. Requests that meet the criteria of both of the nested statements are counted. If the count exceeds 1,000 requests per five minutes, the rule action triggers. Requests that do not meet the criteria of both of the nested statements are not counted towards the rate limit and are not affected by this rule.

      You cannot nest a RateBasedStatement inside another statement, for example inside a NotStatement or OrStatement . You can define a RateBasedStatement inside a web ACL and inside a rule group.

      Returns:
      this

    • rateBasedStatement

      @Stability(Stable) public CfnWebACL.StatementProperty.Builder rateBasedStatement(CfnWebACL.RateBasedStatementProperty rateBasedStatement)
      Sets the value of CfnWebACL.StatementProperty.getRateBasedStatement()

      Parameters:
      regexPatternSetReferenceStatement - A rule statement used to search web request components for matches with regular expressions.

      Each regex pattern set rule statement references a regex pattern 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, AWS WAF automatically updates all rules that reference it.

      Returns:

      ruleGroupReferenceStatement - A rule statement used to run the rules that are defined in a RuleGroup . To use this, create a rule group with your rules, then provide the ARN of the rule group in this statement.

      You cannot nest a RuleGroupReferenceStatement , for example for use inside a NotStatement or OrStatement . You can only use a rule group reference statement at the top level inside a web ACL.

      Returns:

    • sizeConstraintStatement

      @Stability(Stable) public CfnWebACL.StatementProperty.Builder sizeConstraintStatement(IResolvable sizeConstraintStatement)
      Sets the value of CfnWebACL.StatementProperty.getSizeConstraintStatement()
      Parameters:
      sizeConstraintStatement - 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 AWS WAF to inspect the request body, AWS WAF inspects only the number of bytes of the body up to the limit for the web ACL. By default, for regional web ACLs, this limit is 8 KB (8,192 kilobytes) and for CloudFront web ACLs, this limit is 16 KB (16,384 kilobytes). For CloudFront web ACLs, you can increase the limit in the web ACL AssociationConfig , for additional fees. If you know that the request body for your web requests should never exceed the inspection limit, you could use a size constraint statement to block requests that have a larger request body size.

      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.

      Returns:
      this
