Vulnerability discussion

Requiring all authorized applications to be in an application whitelist prevents the execution of any applications (e.g., unauthorized, malicious) that are not part of the whitelist. Failure to configure an application whitelist properly could allow unauthorized and malicious applications to be downloaded, installed, and executed on the mobile device, causing a compromise of DoD data accessible by these applications.SFR ID: FMT_SMF_EXT.1.1 #10b

Check content

This validation procedure is performed on both the MDM Administration Console and the Samsung Knox for Android device. Check whether the appropriate setting is configured on the MDM Administration Console: 1. Ask the MDM administrator to display the "Application disable list" setting in the "Android Application" rule. 2. Verify the list contains all pre-installed applications which backup MD data to non-DoD cloud servers (including user and application access to cloud backup services). Note: The following applications are known to be pre-installed public cloud applications, but other applications can be found on other devices: Google Drive, Dropbox, Verizon Cloud, AT&T Locker, Microsoft OneDrive, and Microsoft OneNote. Note: The following applications allows a user to configure a Samsung Account on the device which allows the user to backup files (including S Health data) to Samsung servers, as well as download applications from Samsung Apps (Galaxy Apps) store: Samsung Account application. Note: Refer to the Supplemental document for additional information. If the "Application disable list" configuration is not properly configured, or if the user is able to launch the applications on the list, this is a finding.

Configure the MOS application whitelist to exclude applications with the following characteristics: -backup MD data to non-DoD cloud servers (including user and application access to cloud backup services) Configure the mobile operating system to disable pre-installed applications which backup MD data to non-DoD cloud servers (including user and application access to cloud backup services). On the MDM Administration Console, add all pre-installed applications which backup MD data to non-DoD cloud servers (including user and application access to cloud backup services) to the "Application disable list" setting in the "Android Applications" rule. Note: Refer to the Supplemental document for additional information.

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.
