NMAP – Free Network Scanner for Network Exploration and Security Audits

In Die Hard 4: Live Free or Die Hard, Detective John McClane (Bruce Willis) is dispatched to retrieve hacker Matthew Farrell (Justin Long) because the FBI suspects him of breaching their computer systems. Later, Justin is enlisted to help thwart terrorist mastermind Thomas Gabrial's attempts at total World destruction. In this scene, Farrell demonstrates his Nmap skills.

Defending your network? You would feel comfortable if you know anything about the ins and outs of your own network structure.

Nmap is a free scanner and a very useful network-mapping utility for network exploration and security audits. It determines what hosts are available, what operating systems they’re running, services they are offering, what filters and firewalls are in place to name a few.

I remember watching Die Hard 4, The Bourne Ultimatum and The Girl with the Dragon Tatoo; and Nmap was featured in those movies.
