Fix Recommendation

Configure Samsung Android to disallow installation from unauthorized application repositories.

On the MDM console, for the device, in the "Knox restrictions" group, unselect "allow install unknown sources".

Check Contents

Review device configuration settings to confirm that installation from unauthorized application repositories is disallowed.

This procedure is performed on both the MDM Administration console and the Samsung Android device.

On the MDM console, for the device, in the "Knox restrictions" group, verify that "allow install unknown sources" is not selected.

On the Samsung Android device, do the following:
1. Open Settings.
2. Tap "Apps".
3. Tap the Overflow menu (three vertical dots).
4. Tap "Special Access".
5. Tap "Install unknown apps".
6. Tap a listed app.
7. Verify that "Allow from this source" cannot be enabled.

If on the MDM console "allow install unknown source" is selected, or on the Samsung Android device the user can enable "allow from this source" for an app, this is a finding.
