Risk assessment in computer networks inherent in critical infrastructures

Abstract

This work is devoted to the problem of risk assessment in computer networks that are inherent in critical infrastructures. The work shows the place of the risk assessment process in the global risk management process, as well as its goals, content and objectives. The most important infrastructure nodes and their interrelations are considered. The system of security indicators proposed for risk assessment in computer networks of critical infrastructures. Aspects of risk management of exceeding critical state variables of the threshold values of the crisis range for the object's information technology infrastructure are considered. The main research methods included structural and system analysis. The authors identified the main security threats in automated control systems, and also proposed methods for calculating their stability.
