You didn't mention if you are only looking for NIDS, so I will suggest the ossec hids to you. I have been using it very sucessfully and it has been much more useful the any NIDS that I have ever used (just to be fair, I'm the developer of this project, but I know some ISPs and companies that use it and like). The ossec hids and an open source host-based intrusion detection system. It performs log analysis, integrity checking, rootkit detection, time-based alerting and active response...
*oh yeah, it runs on OpenBSD. My development box is OpenBSD :) I don't need to say anything else :) If you are interested, download it from: http://www.ossec.net/files/ossec-hids-0.7.tar.gz More info: http://www.ossec.net thanks, -- Daniel B.
