Well, I could see straight off the bat that you would be possibly giving up detection on attack responses and malware that is proxy-aware. Most of the malware that gets past our perimeter (and detected by my various detection systems in place) is web-based that users are surfing to. ________________________________ From: Chan, Wilson [mailto:wchan () honolulu gov] Sent: Friday, October 30, 2009 1:48 PM To: snort-users () lists sourceforge net Subject: [Snort-users] Proxy Servers generating false positives It seems that Snort is generating a lot of false positives for the web traffic heading to our internal proxy servers. Instead of creating thresholds/disabling sigs per alert does it make more sense to just use a BPF to filter out port 8080 to our proxy servers? Is this standard practice or will I lose too much on the detection realm? What am I giving up? Thanks! Wilson
