Review the configuration to determine if the Samsung Android devices are disabling unauthorized application repositories. This validation procedure is performed on both the management tool and the Samsung Android device. On the management tool, in the device restrictions, verify that "installs from unknown sources globally" is set to "Disallow". On the Samsung Android device: 1. Open Settings >> Biometric and security >> Install unknown apps. 2. In the "Personal" tab, ensure that each app listed has the status "Disabled" under the app name or that no apps are listed. 3. In the "Work" tab, ensure that each app listed has the status "Disabled" under the app name or that no apps are listed. If on the management tool "installs from unknown sources globally" is not set to "Disallow", or on the Samsung Android device an app is listed with a status other than "Disabled", this is a finding. |
