Bootable: Whether (with the appropriate OS installed on the drive and supporting BIOS on a computer) the drive can be used to boot a computer. Encryption Type: Type of encryption used. Certification: Whether FIPS 140-2 or similar validation has been passed.
The Apple Computer Mac OS X operating system has provided software for disc data encryption since Mac OS X Panther was issued in 2003 (see also: Disk Utility). [citation needed] Additional software can be installed on an external USB drive to prevent access to files in case the drive becomes lost or stolen.
Disk encryption usually includes all aspects of the disk, including directories, so that an adversary cannot determine content, name or size of any file. It is well suited to portable devices such as laptop computers and thumb drives which are particularly susceptible to being lost or stolen. If used properly, someone finding a lost device ...
Hard disk drive (HDD) FDE (self-encrypting drive) Enclosed hard disk drive FDE; Removable hard disk drive FDE; Bridge and Chipset (BC) FDE; Hardware designed for a particular purpose can often achieve better performance than disk encryption software, and disk encryption hardware can be made more transparent to software than encryption done in ...
Disk encryption does not replace file encryption in all situations. Disk encryption is sometimes used in conjunction with filesystem-level encryption with the intention of providing a more secure implementation. Since disk encryption generally uses the same key for encrypting the whole drive, all of the data can be decrypted when the system runs.
The Windows versions of VeraCrypt can create and run a hidden encrypted operating system whose existence may be denied. [48] The VeraCrypt documentation lists ways in which the hidden volume deniability features may be compromised (e.g., by third-party software which may leak information through temporary files or via thumbnails) and possible ...
The encryption method should not waste disk space (i.e., the amount of storage used for encrypted data should not be significantly larger than the size of plaintext). The first property requires defining an adversary from whom the data is being kept confidential. The strongest adversaries studied in the field of disk encryption have these ...
