Check Text ( C-31211r4_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 “Auto-lock” is set to 5 minutes or less.

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