A tool for managing, enforcing and monitoring BitLocker drive encryption across an entire organization from a central location. [5] MBAM consists of administration console which can be accessed using a web browser, as well as an agent which must be installed on every computer in the organization, either manually or using Active Directory. [6]
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]
The attacker having physical access to a computer can, for example, install a hardware or a software keylogger, a bus-mastering device capturing memory or install any other malicious hardware or software, allowing the attacker to capture unencrypted data (including encryption keys and passwords) or to decrypt encrypted data using captured ...
The cryptsetup command-line interface, by default, does not write any headers to the encrypted volume, and hence only provides the bare essentials: encryption settings have to be provided every time the disk is mounted (although usually employed with automated scripts), and only one key can be used per volume; the symmetric encryption key is directly derived from the supplied passphrase.
Windows PowerShell, which has become a component of Windows 7 and later, features two commands that can read and write attributes: Get-ItemProperty and Set-ItemProperty. [10] To change an attribute on a file on Windows NT, the user must have appropriate file system permissions known as Write Attributes and Write Extended Attributes. [11]
FileVault uses the user's login password as the encryption pass phrase. It uses the XTS-AES mode of AES with 128 bit blocks and a 256 bit key to encrypt the disk, as recommended by NIST. [11] [12] Only unlock-enabled users can start or unlock the drive. Once unlocked, other users may also use the computer until it is shut down. [3]

Drives with this capability are known as self-encrypting drives ; they are present on most modern enterprise-level laptops and are increasingly used in the enterprise to protect the data. Changing the encryption key renders inaccessible all data stored on a SED, which is an easy and very fast method for achieving a 100% data erasure.
