    This is a list of TCP and UDP port numbers used by protocols for operation of network applications. The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) only need one port for duplex, bidirectional traffic.

  5. Port knocking - Wikipedia

    en.wikipedia.org/wiki/Port_knocking

    In computer networking, port knocking is a method of externally opening ports on a firewall by generating a connection attempt on a set of prespecified closed ports. Once a correct sequence of connection attempts is received, the firewall rules are dynamically modified to allow the host which sent the connection attempts to connect over specific port(s).

  6. Service scan - Wikipedia

    en.wikipedia.org/wiki/Service_scan

    This is different from a port sweep that will only identify open ports, which are assumed to be associated with the default service for that port. The difference is that a port scan and a port sweep will detect that a device has a port open and would assume that the port is associated with the service normally associated with that port.
