Conceptual Model of the Efficiency of Information Security System

The main result of this work is a model of the effectiveness of the information security system. The authors show the feasibility of combining the reconfiguration method and the method of using different types of redundancy elements. To improve the reliability of the information security system, the authors propose to structurally separate two independent systems - the secured information system and the security system of the information system. It is necessary to use subsystems assembled on different components and running different operating systems. The use of the combination of subsystems defined in the developed approach increases the number of independent combinations of reliable subsystems. Thus, it will be possible to get different systems of information security at any given time. The proposed structure of the information security system can operate in three modes (considering impact, not considering impacts, and combined). Thus, switching between subsystems of protection is not subject to external influences. Even though the approach described in this paper will increase the complexity of the information security system, there will be an increase in the efficiency of the information security system with a slight increase in cost.
