Windows 11 systems must use a BitLocker PIN for pre-boot authentication.

Description
If data at rest is unencrypted, it is vulnerable to disclosure. Even if the operating system enforces permissions on data access, an adversary can remove nonvolatile memory and read it directly, thereby circumventing operating system controls. Encrypting the data ensures that confidentiality is protected even when the operating system is not running. Pre-boot authentication prevents unauthorized users from accessing encrypted drives.

For AVD implementations with no data at rest, this is NA. If the following registry value does not exist or is not configured as specified, this is a finding: Registry Hive: HKEY_LOCAL_MACHINE Registry Path: \SOFTWARE\Policies\Microsoft\FVE\ Value Name: UseAdvancedStartup Type: REG_DWORD Value: 0x00000001 (1) If one of the following registry values does not exist or is not configured as specified, this is a finding.

Fix Text (F-56663r1186369_fix)

Configure the policy value for Computer Configuration >> Administrative Templates >> Windows Components >> BitLocker Drive Encryption >> Operating System Drives "Require additional authentication at startup" to "Enabled" with "Configure TPM Startup PIN:" set to "Require startup PIN with TPM" or with "Configure TPM startup key and PIN:" set to "Require startup key and PIN with TPM". If Network Unlock is active, select "Configure TPM startup PIN:" and set to "Require startup PIN with TPM". If Network Unlock is not active, select "Configure TPM startup key and PIN:" and set to "Require startup key and PIN with TPM".
