In September 2019 a new update was released (KB4516071 [28]) changing the default setting for BitLocker when encrypting a self-encrypting drive. Now, the default is to use software encryption for newly encrypted drives. This is due to hardware encryption flaws and security concerns related to those issues. [29]
Additionally, it may be possible to reboot the computer into an attacker-controlled operating system without cutting power to the drive. When a computer with a self-encrypting drive is put into sleep mode, the drive is powered down, but the encryption password is retained in memory so that the drive can be quickly resumed without requesting the ...
The Opal Storage Specification is a set of specifications for features of data storage devices (such as hard disk drives and solid state drives) that enhance their security. For example, it defines a way of encrypting the stored data so that an unauthorized person who gains possession of the device cannot see the data.
ClevX is introducing a new self-encrypting platform, available for internal and external SSDs and HDDs.
Note that this does not imply that the encrypted disk can be used as the boot disk itself; refer to pre-boot authentication in the features comparison table. Partition: Whether individual disk partitions can be encrypted. File: Whether the encrypted container can be stored in a file (usually implemented as encrypted loop devices).
With a software implementation, the bootstrapping code cannot be encrypted however. For example, BitLocker Drive Encryption leaves an unencrypted volume to boot from, while the volume containing the operating system is fully encrypted. With full disk encryption, the decision of which individual files to encrypt is not left up to users' discretion.
Software solutions such as BitLocker, DiskCryptor and the popular VeraCrypt allow the contents of a USB drive to be encrypted automatically and transparently. Also, Windows 7 Enterprise, Windows 7 Ultimate and Windows Server 2008 R2 provide USB drive encryption using BitLocker to Go.
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 ...
