Disables the unused interfaces
Rationale:
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.
Solution
Step 1: Identify the physical name <interface_physical_name> of the unused interfaces that are not disabled
Step 2: For each of the identified interfaces, run the following command
Hostname(config)#interface <interface_physical_name>
Hostname(config-if)#shutdown
