IN_DOSL7_ATTACK
       Triggered when ASM detects that a request violates an ASM security policy for Denial of Service attacks.

DESCRIPTION
       Triggered when detects that a request violates an ASM security policy for Denial of Service attacks

       As of 11.3, this event replaces the VIOLATION_DOS_ATTACK_STARTED and the ATTACK_TYPE_DOS_ATTACK_STARTED attack type.

       The event is invoked on each HTTP request that is involved in a DoS attack--that is, a request that comes from a suspicious
       client IP address or destined to a suspicious URL with the exception of the following:

       When the attack prevention mode is CS challenge (client IP address or requested URL) the event is not triggered for any
       request.  When in rate limit mode (client IP address or requested URL) the event is invoked only for attack requests that
       are not dropped.

       Variable name	   Variable description $DOSL7_ATTACKER_IP  The attacker IP address $DOSL7_MITIGATION	Mitigation method
       which is applied on the current HTTP request

Examples
