Remediation - Manual Procedure
Ensure the following standards concerning encryption of data-at-rest are met:
In accordance with DoD policy, all unclassified DoD data that has not been approved for public release and is stored on mobile computing devices or removable storage media must be encrypted using commercially available encryption technology. This requirement includes all CUI as well as other unclassified information that has not been reviewed and approved for public release. This includes certain Personally Identifiable Information (PII). Examples of common devices requiring DAR encryption are laptops used for telework or TDY and mobile devices such as cellular phones, tablets, etc. approved for processing and storing DoD sensitive data, and CDs, thumb drives (flash media) DVDs and other removable media.
See ASD(NII) Memorandum, Encryption of Sensitive Unclassified Data at Rest on Mobile Computing Devices and Removable Storage Media, 3 Jul 07 for detailed guidance.
