Steve Smaha at Haystack Labs has Stalker. SRI has NIDES. Axcent Technologies has a new piece of intrusion detection software with a graphic interface that makes it extremely easy to understand the output, which they are selling as a higher end product than the Raxco Toolkit. Forgot its name, but it was recently mentioned on this list. Bellcore is developing some stuff, but I don't know if it is ready for market yet. Bellcore, please speak up for yourself. If this sounds confused, please bear in mind that I am a simple country boy and have difficulty keeping up with the technology. Hog Farmer
