TRITON targeted safety instrumented systems. Colonial Pipeline shut down fuel supply to the US East Coast. Stuxnet destroyed centrifuges. Every one of these attacks exploited the same gap — operational technology systems designed for reliability and safety, never hardened for adversarial attack. That gap is your responsibility now.
This course teaches OT cybersecurity the way it applies to control systems, not the way it reads in IT security material. It covers the OT threat landscape, the IEC 62443 framework, zones and conduits, risk assessment, network and system hardening, and the monitoring and response that keep a plant defensible.
The work is anchored in IEC 62443 — the industrial automation and control systems security standard — the Purdue reference model for segmentation, and the distinction between OT and IT priorities that shapes every control decision: availability and safety first, then integrity, then confidentiality.
