A method of discovering whether ports on a network are open and could be receiving or delivering data is known as port scanning. It's also a method of sending packets to certain ports on a host and analysing the answers to find flaws.

Nmap offers multiple scanning methods, each with its own strengths and weaknesses. There are three main types of scans:

Host discovery scans rely on sending TCP packets to every IP address in the target range.
Service discovery scans use ARP requests to determine which IP addresses are reachable by the target's gateway.
OS detection scans send ICMP echo requests to the target IP addresses in order to determine what operating system is running on each host.

Nmap is a network traffic scanning tool that improves on earlier network auditing tools to perform speedy and thorough scans of network traffic. It operates by identifying active hosts and IPs on a network using IP packets, then analysing these packets to offer information on each host and IP, as well as the operating systems they are running.
