Decentralized Access Demarcation System Construction in Situational Center Network

Although there is an understanding in the computer community of the need to improve the cyber protection of the information sector of critical infrastructure and the awareness of the urgent need to implement the best practical and theoretical developments in this area is growing rapidly, the total number of incidents in cyberspace is not significantly decreasing, and the urgency of the search for new technological solutions is only increasing. Without exaggeration, it can be stated that a critically important component of the information protection system is its component—the system of delimiting the access of subjects to the objects of the computer system. In many cases, modern demarcation subsystems are built based on a centralized approach to information security management. This article proposes and justifies a partially decentralized approach to building an information security management system and delimiting access in computer systems so that future security measures can rest on a reliable foundation
