Recurring OT security gaps across energy OT networks
Target Trend
Summary
Hide ▲
Show ▼
A study by OMICRON found recurring cybersecurity gaps across OT networks in substations, power plants, and control centers, exposing critical energy infrastructure to cyber risk. Based on more than 100 installations and several years of deployments, the findings point to broad weaknesses in security, organization, and operations. Common issues included unpatched devices, weak network segmentation, and incomplete asset inventories. The consistency of the findings suggests the exposure is systemic rather than isolated.

OMICRON study reveals recurring OT security gaps
Initial DisclosureOMICRON's study of OT networks in substations, power plants, and control centers worldwide identified recurring security, organizational, and operational weaknesses in PAC systems monitored with StationGuard IDS, including unpatched PAC devices, insecure external connections, weak network segmentation, incomplete asset inventories, VLAN misconfigurations, RTU and SCD mismatches, time synchronization errors, and network redundancy problems.
