Definition: A port scan is a method used by hackers to determine what ports are open or in use on a system or network. By using various tools a hacker can send data to TCP or UDP ports one at a time. Based on the response received the port scan utility can determine if that port is in use. Using this information the hacker can then focus their attack on the ports that are open and try to exploit any weaknesses to gain access.
