Title

The macOS system must prohibit password reuse for a minimum of five generations. (Cat II impact)

Discussion

Password complexity, or strength, is a measure of the effectiveness of a password in resisting attempts at guessing and brute-force attacks. If the information system or application allows the user to consecutively reuse their password when that password has exceeded its defined lifetime, the end result is a password that is not changed as per policy requirements.

Check Content

To check the currently applied policies for passwords and accounts, use the following command: /usr/sbin/system_profiler SPConfigurationProfileDataType | /usr/bin/grep pinHistory If the return is not “pinHistory = 5” or greater, this is a finding.

Fix Text

This setting is enforced using the "Passcode Policy" configuration profile.
