An experimental methodology for assessing the probability and danger of network attacks in automated systems

The paper proposes a new method of conducting an experiment to assess the dynamics of the information conflict “Network attack – Protection system” in automated systems. As a result of the application of the methodology, quantitative values of the initial data necessary for assessing the probability and danger of network attacks in automated systems were obtained. The research method implied an experiment that displayed the dynamics of the information conflict “Network attack – Protection system” in automated systems. The authors developed a methodology to determine the quantitative values of the characteristics, as well as the amount of damage from standard network attacks that affect the elements of automated systems. The use of the results makes it possible to observe the course of the information conflict “Network attack – Protection System” in dynamics, to calculate the probabilistic and temporal characteristics of network attacks and to carry out an accurate quantitative assessment of the danger of their implementation in automated systems in the “CPN Tools” and MathCad software environments. The prospects for using the obtained results deal with the construction of particular models of actual attacks and increase of stability of automated systems.
