View Next Audit VersionInformation
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.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'.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'.
