1.3 CISC-RT-000060

Information

The Cisco router must be configured to have all inactive interfaces disabled.

GROUP ID: V-216740RULE ID: SV-216740r531087

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 router 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.

Solution

Disable all inactive interfaces as shown below.

R4(config)#interface GigabitEthernet3R4(config-if)#shutdownR4(config)#interface GigabitEthernet4R4(config-if)#shutdown
