APPLICATION OF COOPERATIVE GAME THEORY TO ASSESS SYSTEM SECURITY

Stepanov Leonid Victorovich, Salnikova Anastasia Yurievna

System security issues are one of the priorities. To solve it, various measures can be applied that partially or completely neutralize the negative impact (destructive activity) on the system. The publication proposes to apply the theory of cooperative games and the Shapley vector to find the optimal combination of security measures and in relation to destructive activities. The publication examines the main issues of security and introduces the concept of destructive activity, as it summarizes the various types and sources of negative impact on the security of the system. Due to the fact that the neutralization of destructive activity cannot be carried out using only one event, it justifies the application of the theory of cooperative games and the Shapley vector to determine the optimal coalition of activities. A numerical example of the application of the Shapley vector to the problem of safety assessment is considered.
