STIGQter: STIG Summary: Samsung Android 11 with Knox 3.x Legacy Security Technical Implementation Guide Version: 1 Release: 1 Benchmark Date: 20 Nov 2020:

The Samsung Android Work Environment allowlist must be configured to not include applications with the following characteristics: - back up MD data to non-DoD cloud servers (including user and application access to cloud backup services); - transmit MD diagnostic data to non-DoD servers; - voice assistant application if available when MD is locked; - voice dialing application if available when MD is locked; - allows synchronization of data or applications between devices associated with user; and - allows unencrypted (or encrypted but not FIPS 140-2 validated) data sharing with other MDs or printers.

Fix Recommendation

Configure Samsung Android Work Environment to use an application allowlist to not include applications with the following characteristics:

- back up MD data to non-DoD cloud servers (including user and application access to cloud backup services);
- transmit MD diagnostic data to non-DoD servers;
- voice assistant application if available when MD is locked;
- voice dialing application if available when MD is locked;
- allows synchronization of data or applications between devices associated with user; and
- allows unencrypted (or encrypted but not FIPS 140-2 validated) data sharing with other MDs or printers.

The application allowlist does not control user access to/execution of all core and preinstalled applications, and guidance for doing so is covered in KNOX-10-009300.

On the management tool, in the Work Environment application section, before adding an app to the "app installation allowlist", review the app details and privacy policy to ensure the app does not include prohibited characteristics.

NOTE: Refer to the management tool documentation to determine the following:
- If an application installation denylist is also required to be configured when enforcing an "app installation allowlist"; and
- If the management tool supports adding apps to the "app installation allowlist" by package name and/or digital signature or supports a combination of the two.

Review Samsung Android Work Environment configuration setting to determine if the application allowlist is configured to not include applications with the following characteristics:

- back up MD data to non-DoD cloud servers (including user and application access to cloud backup services);
- transmit MD diagnostic data to non-DoD servers;
- voice assistant application if available when MD is locked;
- voice dialing application if available when MD is locked;
- allows synchronization of data or applications between devices associated with user; and
- allows unencrypted (or encrypted but not FIPS 140-2 validated) data sharing with other MDs or printers.

The application allowlist does not control user access to/execution of all core and preinstalled applications, and guidance for doing so is covered in KNOX-10-009300.

This validation procedure is performed only on the management tool Administration Console.

On the management tool, in the Work Environment restrictions section, for each approved app on the "app installation allowlist", review the app details and privacy policy to ensure the app does not include prohibited characteristics.

If on the management tool the Work Environment "app installation allowlist" includes apps with unauthorized characteristics, this is a finding.
