Your company has historically avoided issuing company-owned mobile or wireless devices. A new initiative now seeks to provide laptops to employees, but leadership requires that any data stored locally on the device be encrypted at all times. Which type of drive would meet this requirement?
A self-encrypting drive (SED) contains dedicated hardware in its controller that automatically encrypts every bit of data written to the disk and decrypts it transparently when read. Because the cryptographic operations occur on the drive itself rather than through the host CPU or software, the entire contents-including the operating system, applications, and user files-remain fully encrypted at rest. The other options do not provide built-in, hardware-level full-disk encryption.
