Nmap stands for “Network Mapper“, is one of the best open-source utility available now for network discovery and security auditing.

Nmap sends packets and analyzes the response it gets to discover hosts and services on a computer network. It is one of the most widely used port scanners available today to help you find open ports and detecting security risks on a network.

This is the first step for an attacker to get information about the network of targets and identify a potential way to launch an attack. An attacker will know about the services running on open ports along with their version, which helps in determining vulnerabilities for the corresponding version.
