Abstract

Purpose of the article: development of a mechanism for evaluating the actions of agents of complex information systems from the point of view of information security. Research method: game-theoretic models using stochastic modeling methods. The result: typical operations of the violator and defender are defined. A game-theo retic model based on a game with nature has been developed to determine the results of an attack on a separate element of a complex network. Based on the zero-sum game, a model of agent confrontation based on the resu lts of the game with nature has been developed. For the game with nature and the zero-sum game, the stra tegies of agents’ actions are defined. A formal description of the model is given, and it is shown that the simulation result is determined by six parameters that do not depend on a particular type of network graph.
