RE: Cisco CTR

["Alan Shimel" <alan () latis com>]

Our product Border Guard release 4.2 has the same functionality built in
now, we actually block the attacks based on two criteria:

1. Is the attack aimed at an accessiable device (device at destination
IP and port open)
2. Does that device have the vulnerability that this attack exploits.

I would be interested to hear from Rob and some of the others out there
how that differs from what cisco is offerring in beta now.  I think
being proactive in blocking attacks at known vulnerable devices is
preferred.

Yes, but nobody patches it THAT quickly.  CTR acts immediately, not a
half-hour later...it would have started scanning by the time the hacker
at the other end notices that he has a shell...
