    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.
