Port Scanner

Port Scanner is the name for the technique used to identify open ports and services available on a network host. It is a process that sends client requests to a range of server port addresses on a host, with the goal of finding an active port; this is not a nefarious process in and of itself. It is sometimes utilized by security technicians to audit computers for vulnerabilities, however, it is also used by hackers to target victims. Hackers typically utilize port scanning because it is an easy way in which they can quickly discover services they can break into.
