Hi

Below link shows how a Cisco router can protect the network from nimda sort
of viruses which contains most of the attacks on cmd.exe with  network based
application recognition. Thats not all, it
recognizes many http based attacks.

details on network based application recognition can get from the link below

Subject: catching cmd.exe


Is there a way to filter all http requests at port 80 that include the
'cmd.exe' directive? I would prefer to simply reject these packets at the
router level. The router in question allows compares of packet data but the
instructions on use are rather cryptic (including masks and hex offsets).

Alternatively, perhaps there is an intrusion detection system that could
catch this? I need an NT solution.

Thanks in advance

Steve Moore
