Information

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 non-volatile 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.

Solution

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'.
