Utilities rely on digital security, such as device identity checks and signed software updates, that a future quantum computer could break. Grid equipment in operational technology (OT) environments, such as relays, controllers, and meters, stays in service for decades. Its security is typically set at purchase and vendors manage the devices. Narrow maintenance windows make it increasingly difficult to implement changes.
CISOs and OT leaders should start and plan today. This research provides guidance as to where utility CISOs and OT leaders should look first and what characteristics make an OT device more critical than others to efficiently tackle quantum readiness.
