Discussion

Auto logout _MUST_ be configured to automatically terminate a user session and log out the after $ODV seconds of inactivity.

NOTE:The maximum that macOS can be configured for autologoff is $ODV seconds.

[IMPORTANT]
====
The automatic logout may cause disruptions to an organization's workflow and/or loss of data. Information System Security Officers (ISSOs) are advised to first fully weigh the potential risks posed to their organization before opting to disable the automatic logout setting.
