Why Threat Intelligence Needs OT Context to Protect Critical Infrastructure
Summary: OT threat intelligence must connect cybersecurity data with the protocols, assets, manufacturers, and processes of operational networks, because the same network activity can mean different things depending on the device and protocol involved - for example, whether communication between an engineering workstation and a protection device using IEC 61850 is expected maintenance, a configuration error, or malicious behavior. The article argues operators should standardize manufacturer advisories such as in CSAF format and correlate them with an accurate asset inventory, and should bring validated detection content into air-gapped environments through offline updates built into the architecture.
Bottom line: An advisory for industrial equipment tells an operator nothing until it is matched against the specific vendor, model, hardware configuration, and firmware version actually installed - and in isolated OT networks, new vulnerabilities and IoCs keep emerging whether or not the network has internet access.
