GROUP ID: V-259551RULE ID: SV-259551r1038913
The macOS must be configured to enforce a minimum password lifetime limit of 24 hours.
This rule discourages users from cycling through their previous passwords to get back to a preferred one.
Note: The guidance for password-based authentication in NIST 800-53 (Rev 5) and NIST 800-63B state that complexity rules should be organizationally defined. The values defined are based on common complexity values, but an organization may define its own password complexity rules.
Solution
Configure the macOS system to set minimum password lifetime to 24 hours.
This setting may be enforced using local policy or by a directory service.
To set local policy to require a minimum password lifetime, edit the current password policy to contain the following within the "policyCategoryPasswordContent":
[source,xml]
[source,bash]
/usr/bin/pwpolicy setaccountpolicies $pwpolicy_file
