Tools to build your own honeypot
A honeypot is a computer or system that an administrator puts online in order to attract attackers. You read correctly: sometimes you want an attacker in your network. A honeypot should be a tempting target that contains no actual sensitive data. If you believe that your network has already been probed or compromised, you can use a honeypot to collect data on the attacker and his methods without giving away vital information. This collection of resources will help you decide how to establish a honeypot on your own network, either by purchasing a commercial product or building your own.
