Vulnerability discussion

Synchronization of data between devices associated with one user permits a user of an MOS 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 MOS 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.1.1 #42

Check content

This validation procedure is performed on both the MDM Administration Console and the LG Android device. Check whether the appropriate setting is configured on the MDM Administration Console: 1. Ask the MDM administrator to display the "Allow Auto Sync" setting in the MDM console. 2. Verify the setting "Allow Auto Sync" is disabled. On the LG Android device: 1. Unlock the device 2. Open the device settings. 3. Navigate to the Auto Sync setting: Settings >> Accounts (or Account & Sync) 4. Verify the list of Auto-Sync data is disabled with the following message and cannot be unchecked. “Auto Sync is disabled. Synchronization is enabled manually by server policy.” If the "Allow Auto Sync" setting is enabled, or if the user is able to enable the setting on the device, this is a finding.

Fix text

Configure the mobile device to disable Google auto sync. On the MDM Administration Console, disable the "Allow Auto Sync" setting.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
