CIS Microsoft Windows 10 Enterprise Release 1909 Benchmark

Audit:

Navigate to the UI Path articulated in the Remediation section and confirm it is set as prescribed. This group policy setting is backed by the following registry location:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\FVE:FDVActiveDirectoryInfoToSt ore

Remediation:

To establish the recommended configuration via GP, set the following UI path to Enabled: Backup recovery passwords and key packages :

Computer Configuration\Policies\Administrative Templates\Windows Components\BitLocker Drive Encryption\Fixed Data Drives\Choose how BitLocker- protected fixed drives can be recovered: Configure storage of BitLocker recovery information to AD DS: Note: This Group Policy path may not exist by default. It is provided by the Group Policy template VolumeEncryption.admx/adml that is included with the Microsoft Windows 7 & Server 2008 R2 Administrative Templates (or newer).

Impact:

None - this value is ignored when the checkbox above it ( Save BitLocker recovery information to AD DS for fixed data drives ) is False (unchecked), as is required in Rule 18.9.11.1.7. If that checkbox is set to True (checked), both recovery passwords and key packages for fixed drives will be saved to AD DS.

Default Value:

BitLocker recovery information for fixed drives is not backed up to AD DS.
