Configuring an application installation policy on Samsung Knox for Android by specifying an application repository involves two steps: (1) Disabling Google Play, (2) Disabling unknown application sources. This validation procedure covers the first of these steps. It is performed on both the MDM Administration Console and the Samsung Knox for Android device. On the MDM Administration Console: 1. Ask the MDM administrator to display the "Enable Google Play" setting in the "Android Restrictions" rule. 2. Verify it is disabled. On the Samsung Knox for Android device: 1. Attempt to locate the "Google Play" application. 2. Verify it is not present on the device. If the "Enable Google Play" is not disabled, or if a user can successfully launch Google Play on the device, this is a finding.

Fix text

Configure the MOS to disable unauthorized application repositories. Configure the OS to disable Google Play. On the MDM Administration Console, disable "Enable Google Play" in the "Android Restrictions" rule.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
