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

	    log local0. "Attacker IP: $DOSL7_ATTACKER_IP"
	    log local0. "Mitigation: $DOSL7_MITIGATION"
