FDE (full disk encryption)
Encryption of all data on a disk (including system files, temporary files, and the pagefile) can be accomplished via a supported OS, third-party software, or at the controller level by the disk device itself. Used with a strong authentication method, this mitigates against data theft in the event that the device is lost or stolen. The key used to encrypt the disk can either be stored on a USB stick or smart card or in a Trusted Platform Module.
