Description
Synchronization of data between devices associated with one user permits a user of a mobile operating system device to transition user activities from one device to another. This feature passes sufficient information between the devices to describe the activity, but app data synchronization associated with the activity is handled through cloud services, which should be disabled on a compliant mobile operating system device. If a user associates both DoD and personal devices to the same Apple ID, the user may improperly reveal information about the nature of the user's activities on an unprotected device. Disabling this service mitigates this risk. SFR ID: FMT_SMF_EXT.1.1 #45
