Properties

ClientSideActionConfig

Configures the request handling that's applied by the managed rule group rules ChallengeAllDuringEvent and ChallengeDDoSRequests during a distributed denial of service (DDoS) attack.

Required: Yes

Type: ClientSideActionConfig

Update requires: No interruption

SensitivityToBlock

The sensitivity that the rule group rule DDoSRequests uses when matching against the DDoS suspicion labeling on a request. The managed rule group adds the labeling during DDoS events, before the DDoSRequests rule runs.

The higher the sensitivity, the more levels of labeling that the rule matches:

  • Low sensitivity is less sensitive, causing the rule to match only on the most likely participants in an attack, which are the requests with the high suspicion label awswaf:managed:aws:anti-ddos:high-suspicion-ddos-request.

  • Medium sensitivity causes the rule to match on the medium and high suspicion labels.

  • High sensitivity causes the rule to match on all of the suspicion labels: low, medium, and high.

Default: LOW

Required: No

Type: String

Allowed values: LOW | MEDIUM | HIGH

Update requires: No interruption
