To determine the average time and time distribution function for the successful implementation of a computer "DDoS attack " on the elements of the telecommunications network of railway transport (TCNRT). Methods: To solve the problem, the methods of general systems theory, information security theory, probability theory, queuing theory, as well as the method of topological transformation of stochastic networks were used. The calculations were performed using the MathCAD software package. Results: We propose a mathematical model of the process of implementation by the violator of the "DDoS attack" on TCNRT and finding the probabilistic-temporal characteristics of the cyber action system of the violator, the purpose of which is to disrupt the transportation management process. Practical relevance: The proposed model provides for finding the initial data for a comprehensive assessment of the stability of the functioning of the TCNRT, functioning in the conditions of the cyber impact of the intruder on the network elements of the TCNRT. It has been established that this model adequately reflects the modeled process, is sensitive to changes in input data, allows obtaining results consistent with logic, as well as identifying appropriate directions for ensuring the cybersecurity of TCNRT. |
