Background. The aim of the study is to develop base principles of a mechanism to minimize damage from DoS/DDoS attacks targeting technological networks of industrial enterprises. Data on information security incidents in such networks were studied and the objective prerequisites for increasing pressure from cybercriminals on technological networks were determined. The specificity of the DoS/DDoS attacks influence on industrial networks, as well as the influence of external influences of destructive data flows on the reliability of these networks, have been studied. Existing methods of DoS/DDoS attacks resistance in corporate networks were analyzed in detail. The reasons why these methods cannot be applied in technological networks have been established.
Materials and methods. The research was carried out on the basis of simulation.
Results. The basic principle of the mechanism for minimizing damage from DoS / DDoS attacks aimed at industrial networks is proposed. Taking into account the specifics of technological networks, a classification of DoS / DDoS attacks was developed, in the development of which special attention was paid to the dynamic parameters of traffic, depending on the mechanism of operation of the attacking software.
Conclusion. The main criteria for determining the state of an attack are obtained, which are statistical traffic parameters: data flow rate, data flow acceleration, entropy, Poisson data flow, Hurst parameter.
