Microsoft released BitLocker Countermeasures [3] defining protection schemes for Windows. For mobile devices that can be stolen and attackers gain permanent physical access (paragraph Attacker with skill and lengthy physical access) Microsoft advise the use of pre-boot authentication and to disable standby power management.
A common purpose of cold boot attacks is to circumvent software-based disk encryption. Cold boot attacks when used in conjunction with key finding attacks have been demonstrated to be an effective means of circumventing full disk encryption schemes of various vendors and operating systems, even where a Trusted Platform Module (TPM) secure cryptoprocessor is used.
Single sign-on: Whether credentials provided during pre-boot authentication will automatically log the user into the host operating system, thus preventing password fatigue and reducing the need to remember multiple passwords. Custom authentication: Whether custom authentication mechanisms can be implemented with third-party applications.
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]
Challenge–response password recovery mechanism allows the password to be recovered in a secure manner. It is offered by a limited number of disk encryption solutions. Some benefits of challenge–response password recovery: No need for the user to carry a disc with recovery encryption key. No secret data is exchanged during the recovery process.
Cain and Abel (often abbreviated to Cain) was a password recovery tool for Microsoft Windows.It could recover many kinds of passwords using methods such as network packet sniffing, cracking various password hashes by using methods such as dictionary attacks, brute force and cryptanalysis attacks.

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.
Unicode passwords are supported on all operating systems since version 1.17 (except for system encryption on Windows). [15] VeraCrypt added the capability to boot system partitions using UEFI in version 1.18a. [15] Option to enable/disable support for the TRIM command for both system and non-system drives was added in version 1.22. [15]
