The Samsung KNOX for Android platform whitelist must not include applications that back up device data to non-DoD cloud servers (including user and application access to cloud backup services).

Overview

Finding ID	Version	Rule ID	IA Controls	Severity
V-69623	KNOX-35-021275	SV-84245r1_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

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 that back up mobile device 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 that allows the user to back up 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.
