| `null` | no | +| [rate\_based\_statement\_rules](#input\_rate\_based\_statement\_rules) | 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.

action:
The action that AWS WAF should take on a web request when it matches the rule's statement.
name:
A friendly name of the rule.
priority:
If you define more than one Rule in a WebACL,
AWS WAF evaluates each request against the rules in order based on the value of priority.
AWS WAF processes rules with lower priority first.

captcha\_config:
Specifies how AWS WAF should handle CAPTCHA evaluations.

immunity\_time\_property:
Defines custom immunity time.

immunity\_time:
The amount of time, in seconds, that a CAPTCHA or challenge timestamp is considered valid by AWS WAF. The default setting is 300.

rule\_label:
A List of labels to apply to web requests that match the rule match statement

statement:
aggregate\_key\_type:
Setting that indicates how to aggregate the request counts.
Possible values include: `FORWARDED_IP` or `IP`
limit:
The limit on requests per 5-minute period for a single originating IP address.
evaluation\_window\_sec:
The amount of time, in seconds, that AWS WAF should include in its request counts, looking back from the current time.
Valid values are 60, 120, 300, and 600. Defaults to 300 (5 minutes).
forwarded\_ip\_config:
fallback\_behavior:
The match status to assign to the web request if the request doesn't have a valid IP address in the specified position.
Possible values: `MATCH`, `NO_MATCH`
header\_name:
The name of the HTTP header to use for the IP address.
byte\_match\_statement:
field\_to\_match:
Part of a web request that you want AWS WAF to inspect.
positional\_constraint:
Area within the portion of a web request that you want AWS WAF to search for search\_string.
Valid values include the following: `EXACTLY`, `STARTS_WITH`, `ENDS_WITH`, `CONTAINS`, `CONTAINS_WORD`.
search\_string:
String value that you want AWS WAF to search for.
AWS WAF searches only in the part of web requests that you designate for inspection in `field_to_match`.
The maximum length of the value is 50 bytes.
text\_transformation:
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass detection.
See https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/wafv2_web_acl#text-transformation
