BitLocker is a logical volume encryption system. (A volume spans part of a hard disk drive, the whole drive or more than one drive.) When enabled, TPM and BitLocker can ensure the integrity of the trusted boot path (e.g. BIOS and boot sector), in order to prevent most offline physical attacks and boot sector malware. [38]

Reports during WinHEC 2005 indicated Microsoft scaled back its plans for NGSCB, so that it could to ship Windows Vista—which had already been beset by numerous delays and even a "development reset"—within a reasonable timeframe; instead of isolating components, NGSCB would offer "Secure Startup" ("BitLocker Drive Encryption") to encrypt ...
The message noted that more recent versions of Windows have built-in support for disk encryption using BitLocker, and that Linux and OS X had similar built-in solutions, which the message states renders TrueCrypt unnecessary. The page recommends any data encrypted by TrueCrypt be migrated to other encryption setups and offered instructions on ...
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.
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.
Some disk encryption software (e.g., TrueCrypt or BestCrypt) provide features that generally cannot be accomplished with disk hardware encryption: the ability to mount "container" files as encrypted logical disks with their own file system; and encrypted logical "inner" volumes which are secretly hidden within the free space of the more obvious ...
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 ...
