Port scanners are designed to probe a server or host for open ports. This is achieved by sending a message to each port, one at a time. The responses received help determine which ports are open and potentially vulnerable to attacks. This functionality is what allows port scanners to attempt communication with any IP-based system by cycling through all valid TCP and UDP port addresses.
