Someone on our IT team is leaving on his own accord. About a month ago before he gave notice he made a comment to me in passing that no one would find the various back doors he had hidden on the network. Short of hiring a network security consultant to completely test our network are there any programs or tips from you guys on how to see if its real or not?
We have ASA firewalls in our datacenters of which he never had access to. he does have access to 2003, 2008 and 2012 servers
