Discussion

Forcing all applications to be installed from authorized application repositories can prevent unauthorized and malicious applications from being installed and executed on mobile devices. Allowing such installations and executions could cause a compromise of DOD data accessible by these unauthorized/malicious applications. SFR ID: FMT_SMF.1.1 #8

Review managed Google Android 16 device configuration settings to determine if the mobile device has only approved application repositories (DOD-approved commercial app repository, EMM server, and/or mobile application store).

This validation procedure is performed on both the EMM Administration Console and the managed Google Android 16 device. 

On the EMM console:

COBO and COPE:

1. Open "Set user restrictions".
2. Verify that "Disallow install unknown sources" is toggled to "ON".
3. Verify that "Disallow installs from unknown sources globally" is toggled to "ON".

On the Google Android 16 device:

COBO and COPE:

1. Open Settings >> Apps >> Special app access.
2. Open "Install unknown apps".
3. Ensure the list of apps is blank, or if an app is on the list, "Disabled by admin" is listed under the app name.

If the EMM console device policy is not set to allow connections to only approved application repositories, or on the managed Google Android 16 device the device policy is not set to allow connections to only approved application repositories, this is a finding.
