0HWJ-02X Changing Port Numbers Ports serve as endpoints for communicating with other devices. Typically, standard port numbers are used for major protocols, but devices that use these port numbers are vulnerable to attacks because these port numbers are well-known. To enhance security, some network administrators prefer to change the port numbers. When a port number has been changed, the new number must be shared between communicating devices, such as computers and servers. If a...
