Physical Hardware Security
If the computer is located in a location accessible by others, it needs to be physically secured. Prevent others from stealing the machine, installing key loggers into the machine’s ports, or other foreign, unapproved devices into your personal computer’s USB interface ports. Consider disabling your USB ports for safety sake. Obviously, if the computer is located in a home, physical hardware security is not as important. Never, plug in a USB flash drive or device that you find on the ground or that unexpectedly arrives.
Consider buying a secure flash drive such as Lok-it that requires a PIN to be entered before it allows access.
