Changing Port Numbers
2KUU-068
Ports serve as endpoints for communicating with other de
vices. 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.
