Performing a nMap scan Find vulnerability detection Step by Step tutorial with kali linux
Nmap (Network Mapper) is a security scanner, originally written by Gordon Lyon (also known by his pseudonym Fyodor Vaskovich),used to discover hosts and services on a computer network, thus building a "map" of the network. To accomplish its goal, Nmap sends specially crafted packets to the target host(s) and then analyzes the responses.
The software provides a number of features for probing computer networks, including host discovery and service and operating-system detection. These features are extensible by scripts that provide more advanced service detection, vulnerability detection,[3] and other features. Nmap can adapt to network conditions including latency and congestion during a scan. The Nmap user community continues to develop and refine the tool.
Nmap started as a Linux-only utility,[4] but porting to Windows, Solaris, HP-UX, BSD variants (including macOS), AmigaOS, and IRIX have followed. Linux is the most popular platform, followed closely by Windows.
