This infographic explains why operational technology (OT) vulnerability management in the electric sector differs from traditional IT approaches. OT environments prioritize safety, reliability, and continuous uptime, making patching less frequent and often risky due to legacy systems and limited maintenance windows. It highlights three common OT vulnerabilities (Schneider Electric Easergy T200, Hitachi Energy RTU500, and Rockwell Automation Stratix devices) and emphasizes that only a small percentage require immediate action. Dragos promotes a risk-based “NOW, NEXT, NEVER” framework that adjusts CVSS scores for OT realities, focusing on operational impact, exploitability, and alternative mitigations like segmentation, monitoring, and access restriction.
