How Do I Turn On BitLocker via Group Policy?

Published in Computer Security 2 mins read

You can turn on BitLocker using Group Policy by configuring the appropriate settings within the Group Policy Management Console (GPMC). Here's how:

1. Open the GPMC

  • Open the Start menu and search for "gpmc.msc."
  • Press Enter to launch the GPMC.

2. Navigate to the Desired Group Policy Object (GPO)

  • In the GPMC, navigate to the domain or organizational unit (OU) where you want to apply the BitLocker settings.
  • Right-click on the selected domain or OU and choose "Create a GPO in this domain, and Link it here...".
  • Enter a name for the GPO and click "OK".

3. Edit the GPO

  • Right-click on the newly created GPO and select "Edit".

4. Locate the BitLocker Settings

  • In the Group Policy Management Editor, navigate to Computer Configuration > Administrative Templates > Windows Components > BitLocker Drive Encryption.

5. Configure BitLocker Settings

  • You'll find various settings related to BitLocker, such as:

    • "Require additional authentication at startup": Enables requiring a PIN or a USB key for BitLocker startup.
    • "Configure BitLocker for operating system drives": Enables BitLocker for operating system drives.
    • "Require a password for BitLocker startup": Enables requiring a password for BitLocker startup.
    • "Configure BitLocker for fixed data drives": Enables BitLocker for fixed data drives.
    • "Configure BitLocker for removable data drives": Enables BitLocker for removable data drives.

  • Double-click on the desired settings to configure them.

  • Enable the settings and configure the desired options.

6. Apply the GPO

  • Close the Group Policy Management Editor.
  • The changes will be applied to the domain or OU you selected in step 2.

Example: To require a PIN or a USB key for BitLocker startup, you would enable the "Require additional authentication at startup" setting and configure the desired options.

Practical Insight: You can use the "Require a password for BitLocker startup" setting to enforce a password requirement for BitLocker. This helps ensure that unauthorized users cannot access the encrypted data.

Solution: If you want to enforce BitLocker encryption for all operating system drives, you would enable the "Configure BitLocker for operating system drives" setting.
