Vulnerability 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 #10

Check content

This validation procedure is performed on both the MDM Administration Console and the LG Android device. Check whether the appropriate setting is configured on the MDM Administration Console: 1. Ask the MDM administrator to display the "Allow unknown sources" setting in the MDM console. 2. Verify the setting is disabled. On the LG Android device: 1. Unlock the device 2. Navigate to the "Unknown sources": Settings >> Security >> Unknown sources 3. Verify "Unknown sources" setting is disabled. If the "Allow unknown sources" setting is enabled, or if the user is able to install the unknown source application, this is a finding.

Fix text

Configure the mobile device to use one or more authorized application repositories. On the MDM Administration Console, disable "Unknown Sources".

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.
