I have seen a rise of attempts to brute force our Administrator account on a awindows domain. I have in place, a Cisco ASA5505 w/ IPS sensor. I'd like to use the IPS sensor to automatically block IP's that brute force after x failed login attempts.
Question is, is there a signature present (we auto update and are current) which will detect this and, what do we need to do to enable / configure this to kill the connection and deny further attempts.
Thanks in advance!
