InformationDisables the unused interfaces
Shutting down the unused interfaces is a complement to physical security. In fact, an attacker connecting physically to an unused port of the security appliance can use the interface to gain access to the device if the relevant interface has not been disabled and the source restriction to management access is not enabled.
NOTE: Nessus has provided the target output to assist in reviewing the benchmark to ensure target compliance.
SolutionConfigure physical interfaces, subinterfaces, and Bridge Virtual Interfaces on the Firepower Management Center:
