Approach to the Evaluation of the Efficiency of Information Security in Control Systems

Abstract: A methodological approach to evaluation of the efficiency of information security in the information-control subsystem of a complex dynamic system is proposed. As an efficiency index, we have used the degree of realization of possibilities of the controlled dynamic system with consideration of damage prevention expressed in the change in the control cycle duration depending on the destructive actions that damage the completeness, integrity, accuracy, reliability, accessibility, and operability of processing of the information necessary for forming management decisions. © 2020, Allerton Press, Inc.
