Assessment of possible damage and reaction time of a complex of countermeasures to the implementation of information security threats special purpose communication networks

In order to determine the optimal algorithm and methods for assessing damage in the event of the implementation of information security threats in special-purpose communication networks, the existing approaches to solving this problem are considered and analyzed. The quality of threat recognition by the adaptive recognition system can be assessed in the form of prevented damage during the implementation of a conflict impact on the communication system. For this, it is advisable to use a standard model for the implementation of threats of conflict impact on the communication network, based on a four-stage strategy of conflict interaction. Using the expression obtained in the work, it is possible to assess the quality of threat recognition by the adaptive recognition system in the form of prevented damage during the implementation of the conflict impact on the communication network. An assessment of the reaction time of a complex of countermeasures to the implementation of threats to information security of a special-purpose communication network in the context of the implementation of centralized and decentralized control has been carried out. The resulting family of dependencies, for specific networks and given technical means, makes it possible to estimate the time parameters of the proposed adaptive routing algorithms, or, according to the specified requirements for control efficiency, form requirements for the performance of technical means of the control system. From the given dependencies it follows that for the considered computational procedures of routing algorithms, the decentralized control method for most types of structures is preferable according to the criterion response time, regardless of the performance of technical means. However, there are such structural characteristics of networks for which the advantage of one or another routing algorithm depends on the ratio of the performance of the technical means of the control system.
