Changing Port Numbers
Ports serve as endpoints for communicating with other devices. Typically, conventional 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, your
Network Administrator may change the port numbers. When a port number has been changed, the new number must be shared with the
communicating devices, such as computers and servers. Specify the port number settings depending on the network environment.
