Most honeypots work on the same concept, a system that has no production activity. You deploy a box that has no production value, any packets going to that box indicate a probe, scan, or attack. This helps reduce both false positives and false negatives. Exampls of such honeypots include BackOfficer Friendly, DTK, ManTrap, Specter, and Honeynets. However, I was just thinking, why bother deploying the box? Why not create a list of Snort rules that generate an alert whenever a TCP/SYN packet or UDP packet is sent to an IP address that has no system? This could incidate a probe, scan or attack, the same principles of a honeypot, but without deploying an actual system. Of course this does not give you the Data Capture capabilites of a honeypot, as there is no system for the attacker to interact with. However, this could be used to help detect scanning or probing activity.
Better yet have snort spoof a reply (i.e. pretend that a valid port is there). Then the attacker comes back later for more giving you more information and wasting more of their time. Then you get a bit of the best of both worlds. I'm sure snort, portsentry or something similar could easily be hacked up to do it. Alternative use port redirects on Linux/OpenBSD to redirect stuff for unused networks to a "legit" server that will reply with basic stuff.
