Method for prioritizing cybersecurity measures in technological systems of industrial critical infrastructure facilities to counter destructive cyberattacks under resource constraints

This paper addresses the problem of ensuring the reliable functioning of technological systems of industrial critical infrastructure facilities under conditions of limited resources and continuously increasing cyber threats. Under the influence of ongoing military and socio-economic factors, the resource provision of industrial critical infrastructure facilities tends to decrease, which necessitates the optimization of available resource allocation for the implementation of cybersecurity measures, particularly with respect to such a critically important component as the technological system. The study is aimed at defining the role and place of the proposed method, as well as providing its step-by-step description through a coherent and structured algorithm for prioritizing cybersecurity measures in technological systems of industrial critical infrastructure facilities to counter destructive cyberattacks under resource constraints. The proposed approaches are based on the principles of resource management theory and elements of operations research (in particular, problems of allocation, prioritization, and optimization of limited resources). In addition, the method enables informed
