Description
FileVault Disk Encryption must be enabled. By encrypting the system hard drive, the confidentiality and integrity of any data stored on the system is ensured. Information at rest refers to the state of information when it is located on a secondary storage device (e.g., disk drive and tape drive) within an organizational information system. Mobile devices, laptops, desktops, and storage devices can be either lost or stolen, and the contents of their data storage (e.g., hard drives and non-volatile memory) can be read, copied, or altered. FileVault Disk Encryption mitigates this risk.
