Finding ID Version Rule ID IA Controls Severity

Blacklisting all applications is required so that only white-listed applications can be installed on the device. 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 and blacklist 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.

Check Text ( C-56705r1_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 install blacklist" setting in the "Android Knox Container -> Container Application" rule.
2. Verify the setting is configured to all applications (specified by the wildcard string ".*").

On the Samsung Knox for Android device:
1. Attempt to install any application that is not configured in the application install whitelist.
2. Verify that the application is blocked from being installed.

If the "Application install blacklist" configuration in the MDM console has the wrong value, or if the user is able to install the application, this is a finding.
Fix Text (F-61011r1_fix)
Configure the mobile operating system to add all applications to the install blacklist.

On the MDM Administration Console, add all applications to the "Application install blacklist" setting in the "Android Knox Container -> Container Application" rule.
