Morgan, Sorry, it's early in the morning, but I'll run through the two polar opposites of blacklisting (suppression) and whitelisting of rules: Blacklist - say I want to stop receiving alerts on sig_id 466 coming from 192.168.5.33; in the threshold file, I would put the following line: suppress gen_id 1, sig_id 466, track by_dst, ip 192.168.5.33 Whitelist - say I only want to trigger alert 466 when it goes to 192.168.5.33; I would disable the alert (via pulledpork, so when I get rules updates it doesn't get re-enabled), and copy the contents over to my local.rules file, changing the destination from $HOME_NET to 192.168.5.33, so that the rule looked as follows: alert icmp $EXTERNAL_NET any -> 192.168.5.33 any (msg:"ICMP L3retriever Ping"; icode:0; itype:8; content:"ABCDEFGHIJKLMNOPQRSTUVWABCDEFGHI"; depth:32; reference:arachnids,311; classtype:attempted-recon; sid:466; rev:5;) I hope this is what you are asking; if not, let me know, Parker _____ From: Morgan Cox [mailto:morgancoxuk () gmail com] Sent: Wednesday, March 03, 2010 5:12 AM To: snort-users () lists sourceforge net Subject: [Snort-users] whitelist rule to 1 ip? Hi. I did ask this a while ago but never got a response. What is the correct way of white-listing a rule for a specific IP . I know that your can suppress warnings of a rule to an IP using the threshold file, but is thee any way to completely whitelist a rule - to 1 IP only? Any help on this will be appreciated. Regards
