Nmap

Nmap

Nmap is a free and open source utility for network discovery, administration and security auditing. It supports ping scanning (determine which hosts are up), many portscanning techniques, version detection (determine service protocols and application versions listening behind ports), and TCP/IP fingerprinting (remote host OS or device identification).

Nmap also offers flexible target and port specification, decoy/stealth scanning, sunRPC scanning, and more.

  • Version Detection - Interrogating listening network services listening on remote devices to determine the application name and version number
  • OS Detection - Remotely determining the operating system and some hardware characteristics of network devices
  • Scriptable interaction with the target - using Nmap Scripting Engine (NSE) and Lua programming language, customized queries can be made
  • Gopher protocol support
  • Smart traceroute
