Web definitions for Nmap
Nmap is free port scanning software distributed by Insecure.Org and designed to detect open ports on a target computer, determine which services are running on those ports, and infer which operating system the computer is running (this is also known as fingerprinting). It has become one of the de-facto tools in any network administrator's toolbox, and is used for penetration testing and general computer security.
