DISA STIG recommends
WN11-00-000030 CAT I
Windows 11 information systems must use BitLocker to encrypt all disks to protect the confidentiality and integrity of all information at rest.
NIST SP 800-53: SC-28(1)
Check
For AVD implementations with no data at rest, this is NA. Verify all Windows 11 information systems (including SIPRNet) employ BitLocker for full disk encryption. If full disk encryption using BitLocker is not implemented, this is a finding. Verify BitLocker is turned on for the operating system drive and any fixed data drives. Open "BitLocker Drive Encryption" from the Control Panel. If the operating system drive or any fixed data drives have "Turn on BitLocker", this is a finding. Note: An alternate encryption application may be used in lieu of BitLocker providing it is configured for full disk encryption and satisfies the pre-boot authentication requirements (WN11-00-000031 and WN11-00-000032).
Fix
Enable full disk encryption on all information systems (including SIPRNet) using BitLocker. BitLocker, included in Windows, can be enabled in the Control Panel under "BitLocker Drive Encryption" as well as other management tools. Note: An alternate encryption application may be used in lieu of BitLocker providing it is configured for full disk encryption and satisfies the pre-boot authentication requirements (WN11-00-000031 and WN11-00-000032).
