Discussion

Requiring all authorized applications to be in an application allow list prevents the execution of any applications (e.g., unauthorized, malicious) that are not part of the allow list. Failure to configure an application allow list properly could allow unauthorized and malicious applications to be downloaded, installed, and executed on the mobile device, causing a compromise of DoW data accessible by these applications. Applications with the listed characteristics have features that can cause the compromise of sensitive DoW data or have features with no known application in the DoW environment. Note: Apple controls for app allow and block lists do not control app clips. App clips must be managed separately. Application note: The application allow list, in addition to controlling the installation of applications on the mobile device (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 preinstalled applications. Core application: Any application integrated into the operating system (OS) by the OS or MD vendors. Preinstalled application: Additional noncore applications included in the OS build by the OS vendor, MD vendor, or wireless carrier. SFR ID: FMT_SMF_EXT.1.1 #8

Check Content

Verify no apps or app clips with the following prohibited characteristics are included in the configuration profile:

- Backs up MD data to non-DoW cloud servers (including user and application access to cloud backup services);
- Transmits MD diagnostic data to non-DoW servers;
- Allows synchronization of data or applications between devices associated with user; 
- Allows unencrypted (or encrypted but not FIPS 140-3-validated) data sharing with other MDs or printers; and
- Backs up own data to a remote system.

This check procedure is performed on the Apple iOS/iPadOS management tool. 

Note: If an organization has multiple configuration profiles, the check procedure must be performed on the relevant configuration profiles applicable to the scope of the review. 

In the Apple iOS/iPadOS management tool:
 
1. Verify the Declarative Device Management (DDM) configuration "Bundle ID" (BundleID) is configured and there are no apps with prohibited characteristics.
2. Verify the Restrictions "allowAppClips" is disabled.

If DDM "Bundle ID" or Restrictions "allowAppClips" is not configured and contains apps with prohibited characteristics, this is a finding.
