Title

LG Android 6.x must not allow backup to remote systems. (Cat II impact)

Discussion

Backups to remote systems (including cloud backup) can leave data vulnerable to breach on the external systems, which often offer less protection than the mobile operating system. Where the remote backup involves a cloud-based solution, the backup capability is often used to synchronize data across multiple devices. In this case, DoD devices may synchronize DoD-sensitive information to a user's personal device or other unauthorized computers that are vulnerable to breach. Disallowing remote backup mitigates this risk. SFR ID: FMT_SMF_EXT.1.1 #40

Check Content

This validation procedure is performed on both the MDM Administration Console and the LG Android device. On the MDM console, do the following: 1. Ask the MDM administrator to display the "Allow Google Backup" settings in MDM console. 2. Verify the setting is disabled. 3. Verify the policy has been assigned to all groups. On the LG Android device: 1. Unlock the device. 2. Navigate to Settings >> General >> Backup & reset. 3. Verify "Back up my data" is disabled (grayed out). If on the MDM console the "Allow Google Backup" setting is enabled or on the LG Android device "Back up my data" is not disabled (grayed out), this is a finding. Note: To disable cloud backup applications, use the application blacklist.

Fix Text

Configure the mobile operating system to disable backup to remote systems (including commercial clouds). On the MDM Administration Console, disable the "Allow Google Backup" setting.
