Description
Applications from various sources (including the vendor, the carrier, and Google) are installed on the device at the time of manufacture. Core apps are apps preinstalled by Google. Third-party preinstalled apps included apps from the vendor and carrier. Some of the applications can compromise DoD data or upload user's information to non-DoD approved servers. A user must be blocked from using such applications that exhibit behavior that can result in compromise of DoD data or DoD user information. The site administrator must analyze all pre-installed applications on the device and block all applications not approved for DoD use by configuring the application disable list. SFR ID: FMT_SMF.1.1 #42

Check Text ( C-56713r4_chk )
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 Knox Container -> Container Application" rule. 2. Verify the list contains all core and pre-installed applications not approved for DoD use by the Approving Official (AO). (Note: Refer to the Supplemental document for additional information.) On the Samsung Knox for Android device: 1. Open the Knox container. 2. Attempt to launch an application that is included on the disable list. (Note: This application should not be visible.) If the "Application disable list" configuration in the MDM console does not contain all core and pre-installed applications not approved by DoD, or if the user is able to successfully launch an application on this list, this is a finding. Note: Core applications are apps installed in the operating system by the OS developer. In addition, third-party pre-installed apps are included in the OS build by the device vendor or wireless carrier.
