A user interface can be quite restrictive. For example, the interface design might not allow a user to exit to a Windows desktop or to log on to the Internet. Should a user interface include such restrictions? Why or why not?
What will be an ideal response?
The answer depends on security issues. In a high security environment, it might be desirable to have the information system launch automatically when a user powers up a workstation. The design also might prevent users from exiting to Windows or obtaining Internet access, due to sensitive data or security concerns. This is the same type of built-in security that a diskless workstation offers. If user options are limited by hardware or software configuration, then fewer security concerns exist.
Of course, no system is foolproof, and system administrators constantly must be vigilant. Ask students whether they ever worked in situations where their workstation processing or data access options were limited purposely, and how that affected their work.
