Port Scanning with Nmap

Discover live hosts, open ports, and running services using Nmap's scan techniques, flags, and output formats for effective network enumeration.

Mar 16, 2026 • 4 min read

Host enumeration is active probing: scanning networks, discovering open ports, fingerprinting services, and identifying operating systems. This is where passive reconnaissance turns into a concrete target list.

Network scanning with Nmap and Masscan maps the attack surface. Service fingerprinting identifies what is running behind each port. OS detection narrows down exploit compatibility and post-exploitation paths.

The subpages cover scanning techniques, port discovery strategies, service identification, and OS fingerprinting methods.
