Drive Encryption
Noun · Security & Infosec
Definitions
Encryption applied to an entire storage drive or volume so the contents cannot be read without the correct key, even if the hardware is removed. It is a core control for lost laptops, stolen servers, and improper media disposal.
In plain English: Encrypting a whole drive so its data stays protected if the device is lost or stolen.
Example: "The missing laptop was still a reportable event, but drive encryption greatly reduced the exposure risk."
