In connected OT environments, network security has become a critical enabler as industrial systems integrate with IT platforms, AI tools, remote services, and legacy assets, increasing the pathways through which cyber risks can propagate.
Standards such as IEC 62443 address these risks through segmentation, defining zones and conduits to enforce defense-in-depth. Secure networks therefore do not eliminate threats — they limit how far compromise can propagate.
Risk = Likelihood × Impact
While organizations may not always reduce threat probability, network architecture can significantly reduce operational impact. In OT environments, segmentation, controlled access, and containment are the most practical mitigation strategies.
To apply mitigation effectively, organizations must understand where risks exist across the OT network and deploy appropriate security solutions to maintain reliable industrial operations.
