Cyber Security Considerations in the Development of I&C Systems for Nuclear Power Plants

Digital technologies have been applied recently to the I&C systems of nuclear power plants. According to this application, cyber security concerns are increasing in nuclear facilities as in IT industries and other process industries. Many reports and standards are issued for cyber security in industrial control systems. Nuclear regulatory requirements based on the standards for industrial control systems have also been announced. However, it does not clearly indicate what I&C system developers should consider in their development. It is suggested that developers consider 1) maintaining a secure development environment during the development of I&C systems and 2) developing the systems to have security features necessary for a secure operation within the operation environment of NPPs in accordance with a secure development process.
