Cable locks
Cable locks are not the strongest of security measures because they can be cut. But it will help to deter theft. For more information on cable locks, see the cable lock section for the CompTIA A+ 220-1001.
Server locks
Servers may be located in locking cabinets for security. The cabinets usually provide for ventilation on the sides for proper airflow.
USB locks
Physical locks exist to block USB ports. This is a second layer of USB security, after disabling the USB interfaces in BIOS and/or the operating system.
