Password history is only required if the DAA deems it necessary for passwords to expire due to the operational risk and mission need. If used, the recommended value is 3 or more. If used, verify the setting has been set correctly 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. 2. Select each security policy iOS devices are assigned to, and in turn, verify the required settings are in the policy. Verify “Passcode history” is checked and set to 3 or more in the iOS security policy. Mark as a finding if the required rule is not set up on the MDM server, if the DAA requires this setting. Note: If there is a finding, note the name of the policy in the Findings Details section in VMS/Component Provided Tracking Database.
