METHODOLOGICAL APPROACH TO ENHANCING THE SECURITY AND RESILIENCE OF CRITICAL INFRASTRUCTURE OBJECTS

The article examines the methodological approach to increasing the safety and stability of critical infrastructure objects, which is an important element of ensuring Ukraine’s national security. In the conditions of modern terrorist threats, military operations, and technological progress, the need to develop effective approaches to the protection of such objects becomes especially relevant. The existing approaches for determining certain levels of guaranteed security for critical infrastructure (CI) objects are analyzed. Their assessment is provided and the shortcomings are identified. The use of a quantitative method for assessing the probability and consequences of risky events at CI facilities is proposed, which allows to increase the accuracy of assessments and the effectiveness of risk management. A mathematical model of cascading effects of various types in the event of danger risks for critical infrastructure objects has been developed, which allows obtaining probabilistic estimates of the development of events under defined scenarios. An algorithm for countermeasures with the appearance of appropriate threats for typical CI objects has been built. Proposals for emergency response measures have been developed, which can be successfully used to make informed decisions about increasing the safety and stability of critical infrastructure objects, for the development of strategic plans and long-term policies regarding the management of critical infrastructure. The proposed approach allows you to assess all threats and analyze possible scenarios of threat implementation, prioritize threats according to their degree of probability, model the likely consequences of threat implementation, taking into account various conditions and risk factors, identify vulnerabilities in the systems of CI objects, create strategies for responding to crisis situations.
