Why should you enable port security on a switch? (Lab 2.2.4.11)
You should enable port security on a switch because switches can be subject to MAC address
table overflow attacks, MAC spoofing attacks, and unauthorized connections to switch ports.
By configuring port security, you will limit the number of MAC addresses that can be learned
on a switch port and disable the port if that number is exceeded.
Why should unused ports on a switch be disabled? (Lab 2.2.4.11)
Unused ports on a switch should be disabled to help secure the network from unauthorized
access.
