The cyber threat to the infrastructure of the United States of America is well known and understood. This threat is against all forms of infrastructure including basic utilities that including communications systems, power and water distribution and production capabilities. Most citizens don’t appreciate the infrastructure behind talking on their new cell phone or in switching on the electric lights in the morning. Electric generating plants convert thermal energy from a boiler (using coal, oil or gas), or a nuclear reactor (using uranium), into mechanical energy which in turn, is converted into the electrical energy we all use in our homes and businesses. The process is extremely complex and requires a substantial amount of automation. Most of this automation comes in the form of digital controls and although this automation significantly increases both the reliability and capacity of the nuclear powered electric generating station, digital controls offer a significant threat to the safe operation of the facility. The need for cyber-security for the nuclear power plant stems from Federal regulations that require the physical protection of such requirements. Although these regulations have been in place for decades, the emergence of cyber-security regulations are only recent. This introduction of new regulations, especially after the emergence of the newer digital technologies has placed a significant resources burden on the nuclear power plant. Initial systems were not designed for required security measures, i.e., password protection and automatic auditing of systems. In addition, the additional regulations are costly to implement. Of course, the electric utility only passes on these costs to the consumer.
