Nmap: The Pentester's One Step Shop to Network Domination
Nmap is one of the best security software in the world. It is free and open source. It is actively developed and new features and improvements are added to it on a daily basis.
Originally, Nmap is a network portscanner. The tool has then been extended to perform service and OS identification. With the addition of the Nmap Scripting Engine (NSE) back in 2008, Nmap is today capable of performing vulnerability scanning and even exploitation.
In this blog, I'll try to describe some of the Nmap capabilities that can be harnessed in blackbox penetration testing.
