Rethinking OT monitoring: from insight to actual risk reduction - Computable.nl

▤ Summary

This article explains how OT monitoring should move beyond visibility and into active risk reduction. It argues that passive monitoring, logging, and clear baselines for normal communication are essential before any prevention controls are added. It also stresses that OT environments require a different approach than IT because availability, legacy assets, and deterministic traffic patterns limit intrusive security measures. The piece frames monitoring as part of broader risk management, compliance, and change management rather than a standalone security objective.
