AOSX-14-000012 - The macOS system must automatically remove or disable temporary user accounts after 72 hours.


If temporary user accounts remain active when no longer needed or for an excessive period, these accounts may be targeted by attackers to gain unauthorized access. To mitigate this risk, automated termination of all temporary accounts must be set upon account creation.

Temporary accounts are established as part of normal account activation procedures when there is a need for short-term accounts without the demand for immediacy in account activation.

If temporary accounts are used, the operating system must be configured to automatically terminate these types of accounts after a DoD-defined time period of 72 hours.

To address access requirements, many operating systems may be integrated with enterprise-level authentication/access mechanisms that meet or exceed access control policy requirements.

NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.


This setting may be enforced using local policy or by a directory service.

To set local policy to disable a temporary user, create a plain text file containing the following:

<string>policyAttributeCurrentTime &lt; policyAttributeCreationTime+259299</string>
<string>Disable Tmp Accounts </string>

After saving the file and exiting to the command prompt, run the following command to load the new policy file, substituting the correct user name in place of 'username' and the path to the file in place of '/path/to/file'.

/usr/bin/sudo /usr/bin/pwpolicy -u username setaccountpolicies /path/to/file
