Re: Help with Suppression

Hello All, I’m resending this because if you can clarify the below: What I’m trying to achieve is the below: Suppress specific signature (done) Suppress specific signature from a specific source IP (done) Suppress specific signature from a specific destination IP (done) Suppress specific signature from a specific IP address by_src and/or by_dst (is this possible?) Global suppress (0:0) a specific source IP (done) Global suppress (0:0) a specific destination IP (done) Global suppress (0:0) a specific IP address by_src and/or by_dst (is this possible?) You mentioned about multiple policies. How can I create multiple policies? Is there a way to place the suppression rules to a different file and include this to snort.lua? Thanks -------------------------------------------------------------------------------------------------------------------------- Hello Russ Yes these are built in rules and i was trying to also add a global suppresion for all signatures. I tried to comment the signature from the builtin rules but that didn't work. Can you please explain a bit more about the multiple policies? How can i implement this?

Are the alerts you are trying to suppress with 0:0 based on builtin rules?? You may be able configure multiple policies differently to work around some cases. Also, I'm curious about your suppression of 119:225 and 119:228. Can you share any data on those like -A cmg output or maybe a pcap?
