For the security conscious, there is always room for another weapon against attackers. Firewalls, intrusion detection systems, packet sniffers — all are important pieces of the puzzle. So too is Honeyd, the "honeypot daemon." Honeyd simulates the existence of an array of server and client machines on your network, including typical traffic between them. The phantom machines can be configured to mimic the signature and behavior of real operating systems, which will trick intruders into poking at them — and revealing themselves to your security staff.
