: The paper considers the practical application of the game-theoretic approach to the task of assessing the security of systems. One of the factors determining the life and activity of any system is its safety. The concept of security is applicable to organizational, economic, engineering, biological and any other types of systems. The security status of the system is determined by many external and internal factors. Among the internal factors include the vulnerabilities inherent in this system, and among the external ones there are many threats that could potentially affect this system. The circumstance of the confrontation between threats on the one hand, and vulnerabilities (measures to eliminate vulnerabilities) on the other, makes it reasonable to use game theory methods to assess the security of a system.The parameters of threats and vulnerabilities, along with quantitative ones, can have a qualitative description, which limits the possibility of using mathematical methods. For this reason, these parameters must be formalized in a numerical form. To solve this problem, it is proposed to use a pairwise comparison of linguistic constructions. The obtained formalized values can be used to construct the game matrix.A feature of the approach proposed in the work is the possibility of its implementation in the form of algorithmic and software that will automate the work of analysts responsible for the formation of tactics and strategies for ensuring the security of any institution or organization. This fact reflects the practical usefulness of the proposed methodology.

Keywords: security system, security threats, system vulnerabilities, measures to counter threats, linear programming, game theory.
