Mobile systems must encrypt all disks to protect the confidentiality and integrity of all information at rest.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity

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 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.

Check Text ( C-64073r1_chk )
Verify mobile systems employ DoD-approved full disk encryption. If full disk encryption is not implemented, this is a finding. If BitLocker is used, verify it is turned on for the operating system drive and any fixed data drives. Open "BitLocker Drive Encryption" from the Control Panel. If the operating system drive or any fixed data drives have "Turn on BitLocker", this is a finding.

Fix Text (F-69257r1_fix)
Install an approved DoD encryption package and enable full disk encryption on mobile systems. BitLocker can be enabled in "BitLocker Drive Encryption" in the Control Panel.
