Title

The shutdown option must be available from the logon dialog box. (Cat III impact)

Discussion

Preventing display of the shutdown button in the logon dialog box may encourage a hard shut down with the power button. (However, displaying the shutdown button may allow individuals to shut down a system anonymously.)

Check Content

Analyze the system using the Security Configuration and Analysis snap-in. (See "Performing Analysis with the Security Configuration and Analysis Snap-in" in the STIG Overview document.) Expand the Security Configuration and Analysis tree view. Navigate to Local Policies -> Security Options. If the value for "Shutdown: Allow system to be shutdown without having to log on" is not set to "Enabled", this is a finding. The policy referenced configures the following registry value: Registry Hive: HKEY_LOCAL_MACHINE Registry Path: \Software\Microsoft\Windows\CurrentVersion\Policies\System\ Value Name: ShutdownWithoutLogon Value Type: REG_DWORD Value: 1

Fix Text

Configure the policy value for Computer Configuration -> Windows Settings -> Security Settings -> Local Policies -> Security Options -> "Shutdown: Allow system to be shutdown without having to log on" to "Enabled".
