To check if the password policy is configured to disable an account for 15 minutes in the event 3 unsuccessful login are attempted, run the following command: sudo pwpolicy getglobalpolicy | tr ' ' '\n' | grep 'minutesUntilFailedLoginReset' If the result is not 'minutesUntilFailedLoginReset=15', and password policy is not controlled by a directory server, this is a finding.

To set the password policy, run the following command: sudo pwpolicy setglobalpolicy 'minutesUntilFailedLoginReset=15'
