This check is not applicable if CAC authentication is used for the security container. 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 policies should be identified as such in the policy title. An example is STIG_iOS_Policy. It is recommended that all non-STIG policies be deleted. 2. Select each security policy iOS devices are assigned to, and in turn, verify the required settings are in the policy. -Note: If there is a finding, note the name of the non STIG-compliant policy in the Findings Details section in VMS/Component Provided Tracking Database. -Launch the MDM console and click on the Policies tab. -Select an iOS security policy to review. -Verify the number of allowed invalid attempts is 10 or less (required action will be initiated after 10 or less invalid attempts). Mark as a finding if number of allowed invalid attempts is not set as required.
