Qué comprueba
BitLocker drive encryption protects data at rest on Windows devices, preventing unauthorized access to the hard drive contents if a device is lost or stolen. Without a properly configured BitLocker policy, devices may store corporate data unencrypted, exposing sensitive information. The policy must enforce encryption on OS and fixed data drives with secure key recovery options.
Valor recomendado
BitLocker enabled on all OS and fixed data drives with XTS-AES 256-bit encryption and Azure AD key escrow
Remediación
Create or update the Intune endpoint protection profile to require BitLocker encryption on operating system and fixed data drives using XTS-AES 256-bit encryption. Configure recovery key escrow to Azure AD to ensure key recovery is possible and set the policy to silently enable encryption without user interaction. Monitor the encryption status report to identify devices that have not completed encryption and remediate any failures.
