honey pot

n. 1. A box designed to attract cracker s so that they can be observed in
action. It is usually well isolated from the rest of the network, but has
extensive logging (usually network layer, on a different machine). Different
from an iron box in that its purpose is to attract, not merely observe.
Sometimes, it is also a defensive network security tactic you set up an
easy-to-crack box so that your real servers don't get messed with. The
concept was presented in Cheswick Bellovin's book Firewalls and Internet
Security. 2. A mail server that acts as an open relay when a single message
is attempted to send through it, but discards or diverts for examination
messages that are detected to be part of a spam run.
