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).
When used in conjunction with a compatible Trusted Platform Module (TPM), BitLocker can validate the integrity of boot and system files before decrypting a protected volume; an unsuccessful validation will prohibit access to a protected system. [6] [7] BitLocker was briefly called Secure Startup before Windows Vista's release to manufacturing. [6]
Encrypting these files is important, as they can reveal important confidential data. 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.
By default, no files are encrypted, but encryption can be enabled by users on a per-file, per-directory, or per-drive basis. Some EFS settings can also be mandated via Group Policy in Windows domain environments. [3] Cryptographic file system implementations for other operating systems are available, but the Microsoft EFS is not compatible with ...
In March 2017, Google introduced Drive File Stream, a desktop application for G Suite (now Google Workspace) customers using Windows and macOS computers that maps Google Drive to a drive letter on the operating system, and thus allows easy access to Google Drive files and folders without using a web browser. It also featured on-demand file ...
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 password. An attacker can take advantage of this to gain easier physical access to the drive, for instance, by inserting extension cables.
The exact pattern of "same-different-same-different" on disk can then be altered to make the watermark unique to a given file. To protect against the watermarking attack, a cipher or a hash function is used to generate the IVs from the key and the current sector number, so that an adversary cannot predict the IVs.
NordLocker is an encryption software with cloud integration. The software uses so called "lockers" - encrypted folders to encrypt and store user files. Users can create an unlimited number of lockers, drop files in to encrypt them, and transfer lockers separately. [8] The app uses client-side encryption to secure files on the user's device ...
