On devices with Windows' BitLocker disk encryption enabled, which corporations often use to increase security, fixing the problem was exacerbated because the 48-digit numeric Bitlocker recovery keys (unique to each system) required manual input, with additional challenges supplying the recovery keys to end users working remotely. Additionally ...
BitLocker originated as a part of Microsoft's Next-Generation Secure Computing Base architecture in 2004 as a feature tentatively codenamed "Cornerstone" [4] [5] and was designed to protect information on devices, particularly if a device was lost or stolen.
Without the old key, the old data becomes irretrievable and therefore an efficient means of providing disk sanitisation which can be a lengthy (and costly) process. For example, an unencrypted and unclassified computer hard drive that requires sanitising to conform with Department of Defense Standards must be overwritten 3+ times; [ 11 ] a one ...
Kon-Boot was originally designed as a proof of concept, freeware security tool, mostly for people who tend to forget their passwords. The main idea was to allow users to login to the target computer without knowing the correct password and without making any persistent changes to system on which it is executed.
BitLocker can work in conjunction with a Trusted Platform Module (TPM) cryptoprocessor (version 1.2) embedded in a computer's motherboard, or with a USB key. [75] However, as with other full disk encryption technologies, BitLocker is vulnerable to a cold boot attack, especially where TPM is used as a key protector without a boot PIN being ...
This key is itself encrypted in some way using a password or pass-phrase known (ideally) only to the user. Thereafter, in order to access the disk's data, the user must supply the password to make the key available to the software. This must be done sometime after each operating system start-up before the encrypted data can be used.
System Restore is a feature in Microsoft Windows that allows the user to revert their computer's state (including system files, installed applications, Windows Registry, and system settings) to that of a previous point in time, which can be used to recover from system malfunctions or other problems.
Volumes encrypted with Bitlocker can be mounted if a recovery key is available. Windows Recovery Environment can also be installed to a hard drive partition by OEMs, [28] and customized with additional tools such as a separate system recovery tool for restoring the computer back to its original state.
