The upgrade of security of automated process control systems

The article is devoted to the main problems of protecting the network interaction of critical information infrastructures and the lines of solving the ones. An approach is formulated that allows one to combine the positive aspects of different ways of solving this task without combining their negative aspects: adaptation of CDSS to the features of technical facilities by dividing its hardware base into functional and interface parts. The technical solution based on the formulated approach, its key characteristics and indicators are described. The security of the technical solution provided by the application of the New Harvard Architecture and the resident security component is grounded. The prerequisites of applying the implementations of the described solution in various fields of industry, business, energy, in the transport and social fields are formulated.
