An organization recently introduced drives that encrypt data within their own hardware. Which method best ensures the device protects data if it is taken from its usual environment?
Enforcing file permissions on the system for all user directories
Implementing a password-protected boot sequence within the system firmware
Relying on a separate operating system module to manage passphrases
Securing cryptographic materials with a specialized processor integrated on the device
Storing cryptographic materials on a specialized processor integrated with the device enforces encryption regardless of system software or boot settings. Firmware-level passwords do not encrypt data; they only restrict startup. An operating system module relies on software controls, which can be bypassed if the storage is removed. File permissions protect access from the operating system standpoint but do not encrypt data at the hardware layer.
