To increase the effectiveness of the fight against cybercrime, developed countries have begun the relevant work to increase the security of their own information and telecommunications networks of general and special purpose. Current global trends in the spread of cybercrime and the intensification of cyberattacks indicate the growing importance of combating it for the further development of society, which in turn leads to the attribution of certain groups of public relations of the cybersphere to the competence of legal regulation. The current situation with cybercrime requires constant improvement of methods of combating cybercrime, development of information systems and methods aimed at ensuring cybersecurity in the country. That is why the authors of this article developed a method for assessing cybersecurity in a special purpose information and telecommunications system. During the research, the authors used the main provisions of communication theory, queuing theory, artificial intelligence, as well as general scientific methods of analysis and synthesis. The difference between the proposed method from the known ones, which determines its novelty, is the possibility of: detection and qualitative interpretation of cyber threats; modeling scenarios of extreme situations caused by the implementation of cyber threats; assessment of risks that have the characteristics of several classes and ranking of assets of the information and telecommunications system according to the degree of their criticality; perform an assessment of the number of critically vulnerable assets of the information and telecommunications system; substantiate the composition and probability of cyber threats that can cause extreme situations in the information and telecommunications system; conducting risk assessment of their implementation in the information and telecommunications system. The practical significance of the proposed method is fatigue, that its application allows to automate the process of analysis of cyber threats and risk assessment of cybersecurity of information and telecommunications system
