Good morning I'm writing you because few days ago the Cisco Pix appliance, installed on the network of my Company, had a crash.
Few seconds before make statefull fail-over (with the standby unit), I could capture the last log messagges and I send you in attach, with some informations about my Pix.
I don't understand which event(s) could have crash the Pix; my syslog server, that log the Pix messagges (logging trap warnings), have reported more session from different internet IP source, that scanning our pubblic IP addresses on port 139/tcp, the IPs target of the scanning not all was allocated an used (tipycally in scannig the attacker try all the IPs of a network class..)
Any information that you can send me are welcomed
