Securing Halden Water's treatment plant: a Purdue-model zone stack from enterprise IT through an IT/OT DMZ down to the PLCs and the pumps and sensors, so a phished laptop no longer has a path to a controller; the eight-domain OT security board — inventory, segmentation, hardening, access, patching across 63 vulnerable devices, monitoring, safety and supply chain; and passive, protocol-aware monitoring of the pump process that flags a new host writing a setpoint while the safety system stays isolated.

IoT & OT Device Security — The OT Security Board

A hands-on mid-level course that secures the operational technology and connected devices running physical processes, where a compromise can stop production or endanger safety. Work the OT security board - eight domains: Inventory, Segmentation, Hardening, Access, Patching, Monitoring, Safety, and Supply Chain - putting safety first, segmenting the network, and monitoring passively, with real passive discovery, Purdue-model zoning, device hardening, and OT-safe patching. Four hands-on activities in every lesson.
