The problem of cybersecurity of computer networks for control of power supply at the level of railroads is analyzed and a graph of the topology of a computer network for control of power consumption is proposed. Based on the Pukhov theory of differential transformations, a number of differential mathematical models are proposed to assess the level of cybersecurity of a computer network for control of power supply. For differential images, a cybersecurity criterion is proposed and the minimax principle is developed for the worst combination of the intensity of cyberattacks and the flow of protective actions. A method of predictive search for an optimal cybersecurity strategy by the extremum analysis of a functional for the case of stochastic intensity of flows of cyberattacks is developed.
