Title

The shutdown option must not be available from the logon dialog box. (Cat III impact)

Discussion

Displaying the shutdown button may allow individuals to shut down a system anonymously. Only authenticated users should be allowed to shut down the system. Preventing display of this button in the logon dialog box ensures that individuals who shut down the system are authorized and tracked in the system's Security event log.
