3.4.1.a: Full Disk Encryption Authentication   Verify that full disk encryption authentication process is implemented separately from native OS authentication


Section 3.4.1.a of PCI DSS states "If disk encryption is used, inspect the configuration and observe the authentication process to verify that logical access to encrypted file systems is implemented via a mechanism that is separate from the native operating system’s authentication mechanism (for example, not using local user account databases or general network login credentials)."

This Action1 query verifies that all Windows endpoints that have BitLocker enabled are compliant with this requirement by making sure that BitLocker is configured as follows:
- Authenticated mode (not in transparent mode, because it’s tied to native authentication mechanism).
- A USB storage device is required as a token and it’s protected by a PIN code, which is changed every 90 days.
- The machine is NOT shared between multiple users, because otherwise the machine-wide token and PIN code as authentication mechanisms will also be shared and this violates other PCI sections.

If all conditions above are met, then the BitLocker configuration is deemed to be valid for the purposes of PCI 3.4.1.
