In the paper, the research problem of cybersecurity in Ukraine and constituent elements of the cybersecurity global index were considered. The study object is the methods of predicting the indicator of the cybersecurity global index in Ukraine based on the trend extrapolation methods using one dynamic sequence. The purpose of the work is to apply predicting methods to build a prediction of the global cybersecurity index in Ukraine.

The k-terminal dynamic fault trees for a system of three IoT-devices connected by a triangle are formed. Based on the fault tree a state and transition diagram is generated. This model can take into account adequately) load-sharing effects between renewable communication channels. Availability characteristics and failure causes characteristics are calculated based on Monte-Carlo simulation and comparative analysis for obtained results is done.
