Keeping Computers Secure If a User Forgets to Log Out
If a user doesn’t log out when he or she finishes using a computer, other people can use the
computer without logging in. They will have access to anything the previous user had access
to, including that user’s home directory and documents. You can prevent this type of
unauthorized access with the idle logout feature.
Idle logout occurs when there is no user activity (such as typing or using the mouse) for a
specified period of time. For example, suppose you enable idle logout after 15 minutes. A
user logs in, works for a while, and then decides to leave the computer and go have a snack,
but doesn’t log out. After 15 minutes, the user returns and must enter a user name and
password again to gain access.
To enable idle logout:
1 In Macintosh Manager, click Computers, and then click Control.
2 Select a computer list, then select “Enable idle log-out” and enter the number of minutes the
computer should wait.
3 Choose a logout option.
If you select “Log user out,” users see a dialog box after idle log out and have the opportunity
to save any unsaved documents, and then they return to the login screen.
If you select “Lock the screen,” the screen goes black and a dialog box appears. Users can
save any unsaved documents, and then they can either enter a password and continue
working or log out.
4 Click Save.
If this feature has been activated and the computer is connected to the network, you can use
a Mac OS X Server administrator password to log in.
