The Samsung Knox for Android platform whitelist must not include applications with the following characteristics: Allows synchronization of data or applications between devices associated with user.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity
V-61185	KNOX-35-021225	SV-75665r1_rule		Medium

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. SFR ID: FMT_SMF_EXT.1.1 #10b

Check Text ( C-62141r1_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 Application" rule. 2. Verify the list contains all pre-installed applications which allow synchronization of data or applications between devices associated with user. Note: The following applications are known to be pre-installed applications which allow synchronization of data or applications between devices associated with user, but other applications can be found on other devices: Google Drive, Dropbox, Verizon Cloud, AT&T Locker, Microsoft OneDrive, and Microsoft OneNote. 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.
