When operational disruption, safety impacts, or environmental consequences are unacceptable, OT security must deliver a higher standard of resilience than is reasonable to expect of our IT security program.
But – OT environments face structural constraints – difficulty patching, legacy assets, and uptime requirements – constraints that make OT programs weaker, not stronger.
This presentation outlines practical ways to build OT security programs that go beyond IT-equivalent controls. We survey techniques ranging from the simplest deny-by-default rules to cyber-informed engineering measures that eliminate entire classes of consequences and attack vectors. We finish with a deeper dive into alternatives and cost scenarios for the most recent “emergency OT isolation” requirements from authorities in the UK, Denmark, Canada, and the United States.
