The use of Euler-Venn diagrams in solving the problem of choosing security measures for automated process control systems

Chernov Denis Vladimirovich

The article proposes a method for selecting protection measures for automated process control systems based on the construction of Euler-Venn diagrams. The method proposed by the author allows to increase the degree of security of information resources of automated process control systems and to raise the overall level of information security of industrial control systems. The review of the most well-known facts of successful attacks on the automated control system for the 1st quarter of 2021 is carried out. The purpose of the study was to develop a method for selecting security measures at each level of the automated process control system using set theory as part of the analysis of basic sets of security measures.
