On Preventing and Detecting Cyber Attacks in Industrial Control System Networks

Abstract

This paper outlines the problem of cybersecurity in OT (operations/operational technology) networks. It provides descriptions of the most common components of these systems, summarizes the threats and compares them with those present in the IT domain. A considerable section of the paper summarizes research conducted over the past decade, focusing on how common the problem is and in which countries it prevails. The article presents techniques most commonly used in the protection of these systems, with many examples from the nuclear industry given.
