Verify Your Control System Asset Inventory

An accurate inventory of programmable logic controllers (PLCs) and other operational technology (OT) assets is essential for effective cybersecurity. Water utilities should regularly verify that all control system devices are accounted for, document key details such as model, firmware version, network location, and function, and promptly update inventories as equipment is added, removed, or replaced. Maintaining a current and validated asset inventory helps organizations identify vulnerable devices, prioritize security updates, and respond more effectively during crises.
