Physical security
Laptops and some other devices have a built-in security slot that allows them to be secured by a cable to a desk to prevent theft.
Some PC case can be padlocked to prevent them being opened. This prevents:
- The BIOS passwords being removed using jumper on the motherbaord and so allowing the machine to be started without them
- The hard drive being removed, copied and replaced
- Theft of small but expensive components e.g. memory and processor
