Probably the best overall resource to help learn nmap is the official website, which contains a ton of helpful information. When you’re just getting started doing CTFs or learning about cybersecurity, nmap gives you the sensation of actually hacking something. In my opinion, the best part about nmap is that it is so easy to use and, frankly, can be a lot of fun. Nmap also features many tools and options that can be used to do things like: perform service and OS detection, scan for vulnerabilities, and evade firewalls.

Not only can we use it to scan every port (both TCP and UDP) on a computer, we can also use it to scan an entire network to try and identify all possible targets. The term nmap is short for ‘network mapper’.

This room tackles a tool that is totally ubiquitous in penetration testing and hacking in general: nmap. This page contains a walkthrough and notes for the nmap room at TryHackMe.
