Overview

A RateBasedRule is identical to a regular Rule, with one addition: a RateBasedRule counts the number of requests that arrive from a specified IP address every five minutes. For example, based on recent requests that you've seen from an attacker, you might create a RateBasedRule that includes the following conditions:

  • The requests come from 192.0.2.44.

  • They contain the value BadBot in the User-Agent header.

In the rule, you also define the rate limit as 15,000.

Requests that meet both of these conditions and exceed 15,000 requests every five minutes trigger the rule's action (block or count), which is defined in the web ACL.

#match_predicatesArray<Types::Predicate>

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

Returns:

#metric_nameString

A friendly name or description for the metrics for a RateBasedRule. The name can contain only alphanumeric characters (A-Z, a-z, 0-9); the name can\'t contain whitespace. You can\'t change the name of the metric after you create the RateBasedRule.

Returns:

  • (String)

    A friendly name or description for the metrics for a RateBasedRule.

#nameString

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

Returns:

  • (String)

    A friendly name or description for a RateBasedRule.

#rate_keyString

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

Possible values:

  • IP

Returns:

  • (String)

    The field that AWS WAF uses to determine if requests are likely arriving from single source and thus subject to rate monitoring.

#rate_limitInteger

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

Returns:

  • (Integer)

    The maximum number of requests, which have an identical value in the field specified by the RateKey, allowed in a five-minute period.

#rule_idString

A unique identifier for a RateBasedRule. You use RuleId to get more information about a RateBasedRule (see GetRateBasedRule), update a RateBasedRule (see UpdateRateBasedRule), insert a RateBasedRule into a WebACL or delete one from a WebACL (see UpdateWebACL), or delete a RateBasedRule from AWS WAF (see DeleteRateBasedRule).

Returns:

  • (String)

    A unique identifier for a RateBasedRule.
