Large-scale digital transformation initiatives over the last decade mean that cyber-physical systems are now intertwined with many manufacturing and industrial processes. These intelligent systems use computing, networking and sensors to help monitor, control and optimize physical environments. There are also IoT devices connecting IT and OT environments, and smart devices get created and sold to other businesses or customers.
Blending the physical and virtual is central to Industry 4.0, but this blurring of the lines between the physical and digital worlds carries cybersecurity risks. Some of the biggest cyberattacks in recent years targeted critical infrastructure and manufacturing sectors, where cyber-physical systems and IoT devices feature heavily. This article outlines how the use of digital twins in cybersecurity can help to reduce risks in an increasingly connected world.
