The Motorola Android Pie must be configured to not allow backup of [all applications, configuration data] to locally connected systems.
Data on mobile devices is protected by numerous mechanisms, including user authentication, access control, and cryptography. When the data is backed up to an external system (either locally connected or cloud-based), many if not all of these mechanisms are no longer present. This leaves the backed-up data vulnerable to attack. Disabling backup to external systems mitigates this risk.

Review Motorola Android device configuration settings to determine if the capability to back up to a locally connected system has been disabled.
This validation procedure is performed on both the MDM Administration Console and the Android Pie device.
On the MDM console: 1. Open Device Restrictions. 2. Open Restrictions settings. 3. Verify "Disallow usb file transfer" is selected.
On the Android Pie device: 1. Plug USB cable into Android Pie device and connect to a non-DoD network-managed PC. 2. Go to Settings >> Connected devices >> USB. 3. Verify "No data transfer" is selected.
If the MDM console device policy is not set to disable the capability to back up to a locally connected system, or on the Android Pie device, the device policy is not set to disable the capability to back up to a locally connected system, this is a finding.
