Severity: 3-Major


A challenge is issued on a bot that is detected as benign bot. That challenge may make the bot un-usable.


A challenge is being performed, regardless of the action defined on the signature.


A bot sends traffic that matches the bot signature. The signature is defined as benign. The signature doesn't have domain name configured, so no reverse dns lookup can be made.



Fix Information

The system db parameter proactive_defense_exclude_benign_bots was added to exclude benign bots from client side challenge.
