What is BitLocker Drive Encryption?
BitLocker Drive Encryption it’s a security feature in the Windows Vista operating system that provides protection for your computer and data stored on the operating system volume. BitLocker encrypts the data stored on a computer running Windows Vista even if the computer is tampered with when the operating system is not running. Protects against “offline attacks,” attacks which is made by disabling the operating system, and also by physically removing the hard drive to attack the data separately.
Trusted Platform Module (TPM) that BitLocker uses provide protection for your data from theft or unauthorized viewing by encrypting the entire Windows volume, and assures early boot component integrity also protects during system startup. So If ever the startup information has changed, the BitLocker will enter recovery mode, and you will need a recovery password to regain access to the data.
BitLocker is designed for systems that have microchip and BIOS that are TPM compatible. A compatible TPM is defined as a version 1.2 TPM. A compatible BIOS must support the TPM and the Static Root of Trust Measurement as defined by the Trusted Computing Group.
