Simulation of Complex Objects Network Infrastructure to Solve the Problem of Counteraction to Cyber Attacks
In this article, the authors propose an approach to modeling the network infrastructure of complex large-scale objects, including critical ones, using graph theory. The aim of the study is to develop a mathematical model of the network infrastructure of complex large-scale objects, allowing to formalize the target function of the object and cyber attacks aimed at disrupting its objective function. The research method consists in representing the network infrastructure of a complex object as a directed graph, describing the objective function as a set of routes on the graph, and systematizing cyber attacks in the form of unary operations on the graph. The result of the study is a graph model describing the network infrastructure of complex large-scale objects, taking into account the objective function performed by them. Different types of target functions are presented, cyber attacks on the network infrastructure of objects are described. The completeness of the developed graph model is conrmed by the stated and proved theorem. The research results are necessary for the mathematical formulation of cyber attacks prevention problem
