HoneyPot

A honeypot is an internet attached server which is expressly set up to act as a decoy to lure potential hackers, crackers and script kiddies. Once attracted the intruder's activities is studied and monitored to determine the vulnerabilities of the system, thereby learning where the system needs to be redesigned to ensure complete impregnability.

Honeypots are designed to mimic systems which appeal to an intruder but at the same time limits the access to an entire network. This guarantees the hacker can be caught and stopped while trying to obtain root access to the system. Most honeypots are installed inside firewalls so that they can be better controlled. A firewall in a honeypot works in the opposite way that a normal firewall functions: instead of restricting what comes into a system from the Internet, the honeypot firewall allows all traffic to come in from the Internet and restricts what the system sends back out.
