Overview
This Memorandum addresses the protection of federal agency information that is either "accessed remotely or physically transported outside of the agency’s secured, physical perimeter." It specifically requires that agencies encrypt all data stored on mobile computing devices, such as laptops and PDAs, unless the data has been determined by the designated agency official to be non-sensitive.
