Rule version KNOX-17-007300 · STIG v1 · 2026-08-07

Discussion

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.

Check

Review the configuration to determine if the Samsung Android device is 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, from the "USB for charging phone" notification, verify that "Transferring files/Android Auto" and "Transferring images" are not options.

If on the management tool "USB file transfer" is not set to "Disallow", or on the Samsung Android device "Transferring files/Android Auto" or "Transferring images" options are available, this is a finding.

Fix

Configure the Samsung Android device to disable USB mass storage mode.

On the management tool, in the device restrictions, set "USB file transfer" to "Disallow".

DeX drag and drop file transfer capabilities will be prohibited, but all other DeX capabilities remain usable.
