Description

USB mass storage mode enables the transfer of data and software from one device to another. This software can include malware. When USB mass storage is enabled on a mobile device, it becomes a potential vector for malware and unauthorized data exfiltration. Prohibiting USB mass storage mode mitigates this risk.

Review the configuration to determine if the Samsung Android devices are disabling USB mass storage mode. This validation procedure is performed on both the management tool and the Samsung Android device. On the management tool, in the device restrictions, verify "USB file transfer" has been set to "Disallow". On the Samsung Android device, first, connect the device to a computer with a USB cable. From the home screen, swipe down and view all device notifications. Verify that a "File Transfer" is not an option. Note: Connecting to the device and viewing notifications (without the policy being applied) will show a series of options including "Transferring files". If on the management tool "USB file transfer" is not set to "Disallow", or on the Samsung Android device a "File Transfer" is an option, this is a finding.
