Bridging the Divide: Making IT/OT Convergence Work with IEC 62443

As IT and OT systems within organizations become increasingly intertwined, new challenges emerge along with new risks to the availability and resilience of critical infrastructure. This session demystifies the IEC 62443 series, breaking down its structure, key concepts, and practical application across converged environments. We'll explore real-world convergence examples, walk through the process of assigning and assessing security levels (SL-T, SL-A, SL-C), and clarify concepts like risk assessment, zoning, and functional requirements. After this session you'll leave with a sharper view of how to apply IEC 62443 as a common security language across your entire organization.
