The Workstation Installation/Operation Manual Version 2 Document 51540 Rev. B1 4/8/02
3.1.3 Security and Security Profiles
There are numerous workstation security controls to ensure that the workstation is not disabled by unauthorized
users. Two basic areas of protection are covered:
• Hardware Security.
• Software Security.
Hardware Security
Workstation power connections are secured with special hardware, and the computer power switch is disabled.
With proper line current surge protection and UPS power supply installed, the workstation is well protected from
system failures.
In addition, a dedicated workstation supervisor device is available that monitors its operation through a direct
connection with the motherboard's bus. In the event the workstation goes off-line, either from mechanical/electrical
failure or tampering, an alarm is sounded by the device to notify personnel of monitoring loss. (For more informa-
tion on the Workstation Supervisor, See Section 1.1.3).
Software Security
Software security provides workstation operation protection through three methods:
• Control/Command Key Lockouts.
• Application auto-start.
• Operator Security Profiles.
Control/Command keys or application switching keys are standard computer commands which provide computer
users convenient methods to shut down and re-boot the computer. Other key commands allow easy access to
system resources and programs outside of the current application. All of these commands can be disabled by the
system administrator.
For details on how to disable application switching, refer to the Launcher section of the System Utilities manual.
In the event that the system is shut down or re-booted, the monitoring software is set to automatically load during
the start-up process. With the control key lockouts in place, this makes it extremely difficult to circumvent the
workstation.
NOTE: Changing the application switching setting requires rebooting the com-
puter.
