Description
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. Applications with the listed characteristics have features that can cause the compromise of sensitive DoD data or have features with no known application in the DoD environment. Application note: The application whitelist, in addition to controlling the installation of applications on the MD, must control user access/execution of all core and preinstalled applications or the MD must provide an alternate method of restricting user access/execution to core and pre-installed applications. Core application – any application integrated into the operating system (OS) by the OS or mobile device (MD) vendors. Pre-installed application – additional non-core applications included in the OS build by the OS vendor, MD vendor, or wireless carrier. SFR ID: FMT_SMF_EXT.1.1 #8b

Review Samsung Android 7 with Knox configuration settings to determine if the mobile device has an application disable list configured to include applications with the following characteristics:

-Back up MD data to non-DoD cloud servers (including user and application access to cloud backup services).

This validation procedure is performed only on the MDM Administration Console.

On the MDM console, do the following:
1. Ask the MDM administrator to display the "Application disable list" setting in the "Android Application" rule.
2. Verify the list contains all applications which backup MD data to non-DoD cloud servers (including user and application access to cloud backup services).

If the MDM console "Application disable list" is not properly configured or on the Samsung Android 7 with Knox device, the user is able to launch the applications on the list, this is a finding.

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.
