Port scanning and Nmap 3.5
"Inspired by the release of Nmap 3.5, the latest version of the award-winning network security tool, I've been exploring network security issues for a couple of weeks now. Nmap's major skill is port scanning -- learning which ports on a machine are "open" and what applications are using them. Sound network security planning dictates that you take a look at your network machines to see what the bad guys can see from outside."
