KNOX-07-001600 - The Samsung whitelist must be configured to not include applications that Back up MD data to non-DoD cloud servers.

Information

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.
