Yes its normal. Its just informing you that CSC-SSM module can scan only scan the specified traffic.

If any other traffic like https or if you are looking at scanning tftp traffic or some netbios traffic it won't be scanned by the csc module.

Your config for diverting the traffic through the CSC would look like:

access-list csc extended permit tcp any any eq ftp

access-list csc extended permit tcp any any eq www

access-list csc extended permit tcp any any eq https

access-list csc extended permit tcp any any eq pop3

!

class-map cscmap

match access-list csc

!

policy-map cscpolicy

class cscmap

csc fail-open

!

service-policy cscpolicy interface outside

service-policy cscpolicy interface inside

!
