Abstract
The task of building models and analyzing the protection of continuous monitoring systems from cyber-attacks is currently becoming particularly relevant due to the rapid development and implementation of monitoring systems in various industries. Despite the constant development of the field, the task of identifying potential information threats to such systems remains at the same level with the development of means and methods of conducting cyber-attacks. The purpose of this work is to develop a DDOS attack model for a spatially distributed continuous monitoring system with a hierarchical structure of connections between sensors. To define various criteria for the functionality of a spatially distributed continuous monitoring system when exchanging messages between the elements (sensors) of the system. Results. During the study, the authors performed a number of experiments using computer modeling. Computer simulations of DDoS attacks on a spatially distributed continuous monitoring system were carried out in cases of system operation with and without load. The criteria of the system's operability over time are defined, and an approach to determining the system's serviceability based on Amdahl's law and evaluating the acceleration of the system is proposed. It is shown by the example of computer experiments that the model has practical significance, and the results of applying the model can be used to reduce the risks associated with DDoS attacks.
