Microsoft BitLocker on Windows 8

Windows 8 is not recommended for campus use at this time. However, if you have to support a Windows 8 portable device, it must be encrypted. At this time, BitLocker is available to accomplish this task on all Windows 8 portable devices that have a TPM chip and do not run on an ARM platform (such as a Windows 8 RT tablet). Windows 8 devices that run on an ARM platform or those that do not have TPM chips should not be used.

UAB Policy requires all laptop/portable devices owned by UAB or UAB businesses and all personal laptop/portable devices used for UAB business be encrypted. PGP, UAB’s current encryption tool, does not work on Windows 8 and Symantec has not yet set a support date for Windows 8.

BitLocker is an acceptable alternative to encrypt Windows 8 system drives in some circumstances. In the past, BitLocker has been recommended when PGP was incompatible with Windows 7 or specific BIOS versions. Systems that are currently encrypted with PGP should remain encrypted via PGP.  UAB IT is currently researching BitLocker key management solutions and will issue further guidance as available, but in the mean time, BitLocker should be installed using the non-enterprise setup method below.

Non-Enterprise BitLocker Setup

Recommendations for using BitLocker

    • Password set system BIOS
    • TPM chip in the device
    • You must take ownership of the TPM chip
    • Before updating the BIOS, BitLocker must be suspended
    • Escrow the key in some manner
    • Professional/enterprise version of Windows
    • Use a TPM + PIN authentication method
    • System must be formatted NTFS with two volumes

 Escrowing the key

With Windows 8, you may escrow the key in one of the following ways:

  • Save the recovery key to a USB flash drive
This method saves the recovery key to a USB flash drive. This option cannot be used with removable drives.
  • Save the recovery key to a file
This method saves the recovery key to a network drive or other location.
  • Print the recovery key
This method prints the recovery key, but it is not recommended.

It will be up to the department to maintain the escrow recovery keys.
