This video is an in-depth tutorial on using Nmap in Penetration Testing. It covers the rules of engagement, network verification, layer 2, 3 and 4 host discovery, IP list creation, port states, default Nmap scans, and service and version enumeration scans. Additionally, it covers techniques for detection avoidance, including timing of scans, decoy scans, random host scans, spoofing MAC addresses, and fragmented scans. The video also reviews Nmap script sources and shows how to perform SMB, FTP and other vulnerability scans, along with confirming vulnerabilities existence via Metasploit. Finally, it provides an overview of defensive tactics and closing thoughts on Nmap use in network security.
