Cybersecurity Risk Assessment in OT: Navigating the IEC 62443 Framework
In the modern industrial landscape, Operational Technology (OT) systems—which monitor and control physical devices in manufacturing, energy, and infrastructure—are rapidly converging with IT networks. While this integration drives efficiency, it also exposes critical infrastructure to unprecedented cybersecurity risks. A successful attack on an OT environment doesn't just result in data loss; it can cause catastrophic physical damage, long-term operational downtime, and environmental disasters. To address these unique risks, industry professionals turn to international standards. Foremost among these is IEC 62443 , a robust series of standards specifically designed to secure Industrial Automation and Control Systems (IACS). A central pillar of this framework is the Cybersecurity Risk Assessment, which provides the necessary structured approach to identify, analyze, and mitigate risks in an OT environment. Why OT Risk Assessment Differs from IT Traditional IT risk assessments prio...
