Is it possible with that module to filter some of the users filtered (like restricting facebook.com) and others unfiltered? I mean if user based filtering is possible?
In asa,you define what traffic should be sent to csc for scanning purpose.
In the acl where you define the traffic,add an entry denying the source ip addresses for which you do not want filtering to be done.
match access-list CSC-TRAFFIC
access-list CSC-TRAFFIC line 1 extended deny tcp host x.x.x.x any eq 80
access-list CSC-TRAFFIC line 2 extended permit tcp any any eq 80
access-list CSC-TRAFFIC line 3 extended permit tcp any any eq smtp
In the above example,web traffic from x.x.x.x will not be sent to csc...
