I'm just testing snort right now and was wondering if someone could tell me if the following rule is wrong: alert tcp any any -> $LAN any ( content: "GET /banner/"; \ msg: "banner test";) It's in the myrules.rules file and is included in the snort.conf file. If a user from a workstation goes to a website and the website sends a banner, shouldn't there be a log?
No, becaause the GET command will go FROM the lan not TO it. You would want: alert tcp $LAN any -> any any ( content: "GET /banner/"; \ msg: "banner test";)Or for efficiency of not checking _EVERY_ tcp packet only check useful ones going to a normal http server:
alert tcp $LAN any -> any 80 ( content: "GET /banner/"; flags:A+; \ msg: "banner test";) ------------------------------------------------------- This SF.net email is sponsored by: VM Ware With VMware you can run multiple operating systems on a single machine.
