| | Port scanner - definition of Port scanner in Encyclopedia |
 | | Ports are places where data can enter the computer, and be run by a process on the computer. | | | Nmap is one of the leading open source software port scanners, and is supplied with most Linux and UNIX distributions; it is also available for Microsoft Windows operating system machines. | | | Many exploits depend upon finding open ports and sending to them strings of data that cause the computer operating system to malfunction in a predictable way (called a buffer overflow) that can be exploited, for instance to load more software which enables other tasks to be undertaken. |

| | What is port scanning? - A Word Definition From the Webopedia Computer Dictionary |
| | Port scanning has legitimate uses in managing networks, but port scanning also can be malicious in nature if someone is looking for a weakened access point to break into your computer. | | | Since a port is a place where information goes into and out of a computer, port scanning identifies open doors to a computer. | | | There is no way to stop someone from port scanning your computer while you are on the Internet because accessing an Internet server opens a port, which opens a door to your computer. |

| | Half open port scanner |
| | Ports scans are not illegal in many places, in part because they don't actually compromise the system, in part because they can easily be spoofed, so it is hard to prove guilt, and in part because virtually any machine on the Internet can be induced to scan another machine. | | | An attacker will often sweep thousands (or millions) of machines rather than a single machine looking for any system that might be vulnerable. | | | Port scans are always automated through tools called Port Scanners. |
