Passive Monitoring & Active Collection for a Complete OT Asset Inventory
Summary: Dragos describes a layered OT asset-discovery approach that pairs passive network monitoring with controlled, read-only active collection, including a software agent deployed on Windows-based OT devices to query assets that passive sensors cannot observe. The company says legacy equipment, proprietary industrial protocols, segmented architectures, and assets that communicate only during specific operational events leave many owners and operators without a complete, reliable OT asset inventory.
Key Takeaway: The source states that without an accurate, continuously updated view of assets and their connections, teams face persistent blind spots that weaken detection accuracy, slow investigations, and complicate every downstream cybersecurity and operational process.
