Application download must be enabled so iOS updates can be installed over-the-air (OTA) and security updates will be installed as soon as possible. This is a key feature of the security baseline for DoD iOS devices. The MAM server will be responsible for scanning the device periodically and alert if the user has downloaded unapproved applications.

Check Text ( C-31216r4_chk )
This is an iOS security policy set check. Recommend that all checks related to iOS security policy set rules be reviewed using the following procedure.

1. Make a list of all iOS security policies listed on the MDM server that have been assigned to iOS devices and review each policy using the following procedure:
-Have the SA identify STIG compliant and non-compliant policies on the server.
--Log into the MDM server console.
--Click on the Policies tab.
--View all iOS security policies on the server.
-Note: STIG-compliant policy sets should be identified as such in the policy title. An example is STIG_iOS_Policy_Set. It is recommended that all non-STIG/ISCG policy sets be deleted.

2. Select each iOS security policy iOS devices are assigned to, and in turn, verify the required settings are in the policy set.
-Note: If there is a finding, note the name of the non STIG/ISCG-compliant policy set in the Findings Details section in VMS/Component Provided Tracking Database.
-Launch the MDM console and click on the Policies tab.
-Select the iOS security policy.

-Verify “Allow installing apps” is enabled or checked.

Mark as a finding if configuration is not set as required.

Note: With this setting and check WIR-MOS-iOS-G-023, users will be able browse the application store but not purchase and download applications from the store. If a user finds a way to “sideload” an unauthorized iOS application without using the app store, the MAM server will alert that an unauthorized application has been identified on the device.
Fix Text (F-27664r2_fix)
