IT:AD:Bitlocker

A Microsoft technology for encrypting whole hard-drives.

• Advantages:
  • I believe the encyrption is tied to the hardware. You can't just use the HD in another computer.
• Considerations:
  • TrueCrypt development was stopped at some point, and the devs recommended that users convert to Bitlocker as they considered it offered better security.
  • BitLocker encrypts all personal and system files on the drive where Windows is installed, or on data drives on the same computer.
  • If one user unlocks it, all other users on the system can use the hard-drive.
  • It works on the whole hard-drive – and is not to be used on individual files.
    • See EFS
• Disadvantages:
  • Whereas TrueCrypt could be create a virtual hard-drive, I don't think Bitlocker can do that.
