The rapid development of computer technology, the emergence of modern cyber threats with signs of hybridity and synergy put forward strict requirements for the economic component of national security and especially the processes of ensuring the economy cybersecurity. The cybersecurity industry is trying to meet today's requirements by introducing new and more advanced security technologies and methods, but it is believed that such a universal approach is not enough. The study is devoted to resolving the objective contradiction between the growing practical requirements for an appropriate level of cybersecurity of business process contours while increasing the number and technological complexity of cybersecurity threats. Also the fact that threats acquire hybrid features on the one hand, and imperfection, and sometimes the lack of methodology for modeling the behavior of interacting agents of security systems should be taken into account. However, this does not allow timely prediction of future actions of attackers, and as a result, determining the required level of investment in security, which will provide the required level of cybersecurity.The paper proposes the Concept of modeling the behavior of interacting agents, the basis of which is a three-level structure of modeling the subjects and business processes of the contours of the organization and security system, based on modeling the behavior of antagonistic agents. The proposed methodology for modeling the behavior of interacting agents, which is based on the Concept of behavior of antagonistic agents, allows assessing and increasing the current level of security by reducing the number of hybrid threats by 1.76 times, which reduces losses by 1.65 times and increases the time for choosing threat counteraction means by reducing the time to identify threats online by 38 % Author Biographies Oleksandr Milov, Simon Kuznets Kharkiv National University of Economics Nauky ave., 9-А, Kharkiv, Ukraine, 61166 PhD, Professor Department of Cyber Security and Information Technology
