Check Text ( C-31242r8_chk )
This check is not applicable if CAC authentication is used for the security container. Password history is only required if the DAA deems it necessary due to the operational risk and mission need. If used, recommend the value be set at 3 or more. 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 security policy for the security container password is set to disallow 3 or more previously used passwords. Mark as a finding if “Disallow previously used passwords” is not set to 3 or more, if the setting is required by the DAA. Note: If there is a finding, note the name of the policy in the Findings Details section in VMS/Component Provided Tracking Database.
