CISC-RT-000060 - The Cisco switch must be configured to have all inactive layer 3 interfaces disabled.


An inactive interface is rarely monitored or controlled and may expose a network to an undetected attack on that interface. Unauthorized personnel with access to the communication facility could gain access to a switch by connecting to a configured interface that is not in use.

If an interface is no longer used, the configuration must be deleted and the interface disabled. For sub-interfaces, delete sub-interfaces that are on inactive interfaces and delete sub-interfaces that are themselves inactive. If the sub-interface is no longer necessary for authorized communications, it must be deleted.

NOTE: Nessus has provided the target output to assist in reviewing the benchmark to ensure target compliance.


Disable all inactive interfaces as shown below:

SW1(config)# int e4/1 - 11
SW1(config-if-range)# shutdown
SW1(config-if-range)# end
