This is another “Expert Article” that I wrote for my previous consulting firm ISA . I am posting it here for reference only. It was back when Intrusion Prevention Systems (IPS) were entering the market and all the claims about how they were better then Intrusion Detection Systems (IDS). Clients were confused about the differences between the technologies themselves as well as the underlying mechanisms used to detect malware. It was an attempt to explain it so general I.T. and business folks could get a base understanding.
The original URL is here, but at some point I expect it to go away.
