"...For a system administrator who is aware of system security, it is important to carry out a scanning of their own network, and look for vulnerabilities before others do it with not so good intentions.

There are several scanning tools for this purpose, but the article will only look at nmap. Nmap is among the most complete scanners and security tools.

Nmap allows the system administrator to scan the networks in order to know which servers are active and which services they offer. For this purpose, nmap offers several scanning techniques. This article will work on a limited number of them, reviewing (maybe teaching?) some aspects of TCP protocol."
