Check Text ( C-31245r8_chk )
This check is not applicable if CAC authentication is used for the security container. 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. 2. Select each security policy iOS devices are assigned to and, in turn, verify the required settings are in the policy. 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. Note: If there is a finding, note the name of the policy in the Findings Details section in VMS/Component Provided Tracking Database.
