In this article we will discuss Secure Unused Ports, will make brief discussion on Secure Unused Ports, In last article we discuss about Verifying SSH.
A simple method that many administrators use to help secure the network from unauthorized access is to disable all unused ports on a switch. For example, if a Catalyst 2960 switch has 24 ports and there are three Fast Ethernet connections in use, it is good practice to disable the 21 unused ports.
Navigate to each unused port and issue the Cisco IOS shutdown command. If, later on, a port must be reactivated, it can be enabled with the no shutdown command.
It is simple to make configuration changes to multiple ports on a switch. If a range of ports must be configured, use the interface range command.
