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.
