The lack of basic principles of engineering design and discipline has led to some very serious problems in the computer security arena. At the heart of modern power systems are Supervisory Control and Data Acquisition (SCADA) software systems that provide real time control and data management [2]. It is interesting to note that every aspect of a hardware system that is under control of the SCADA architecture is fully instrumented and the operation of the monitored system is totally under management of the control system. However, the software that controls the entire power grid is essentially open loop and uncontrolled. It would be unthinkable to build a complex hardware system without embedding monitors for process control throughout the whole architecture. Ironically, the backbone of modern control systems, SCADA for example, is almost entirely dependent on a software system that is running out of control.
