--
-- Enable the Shield Advanced automatic application layer DDoS mitigation
-- for the protected resource.
--
-- This feature is available for Amazon CloudFront distributions and
-- Application Load Balancers only.
--
-- This causes Shield Advanced to create, verify, and apply WAF rules for
-- DDoS attacks that it detects for the resource. Shield Advanced applies
-- the rules in a Shield rule group inside the web ACL that you\'ve
-- associated with the resource. For information about how automatic
-- mitigation works and the requirements for using it, see
-- <https://docs.aws.amazon.com/waf/latest/developerguide/ddos-advanced-automatic-app-layer-response.html Shield Advanced automatic application layer DDoS mitigation>.
--
-- Don\'t use this action to make changes to automatic mitigation settings
-- when it\'s already enabled for a resource. Instead, use
-- UpdateApplicationLayerAutomaticResponse.
--
-- To use this feature, you must associate a web ACL with the protected
-- resource. The web ACL must be created using the latest version of WAF
-- (v2). You can associate the web ACL through the Shield Advanced console
-- at <https://console.aws.amazon.com/wafv2/shieldv2#/>. For more
-- information, see
-- <https://docs.aws.amazon.com/waf/latest/developerguide/getting-started-ddos.html Getting Started with Shield Advanced>.
-- You can also associate the web ACL to the resource through the WAF
-- console or the WAF API, but you must manage Shield Advanced automatic
-- mitigation through Shield Advanced. For information about WAF, see
-- <https://docs.aws.amazon.com/waf/latest/developerguide/ WAF Developer Guide>.
