Episode notes
AI And Connectivity Raise OT Risk
- AI and interconnected devices lower the barrier for OT attacks, making previously hard targets easier to find and exploit.
- Adversaries now use multi-stage techniques beyond phishing to reach critical infrastructure.
Design For When, Not If, Compromise Occurs
- Assume compromise will happen and design defenses for detection, response, and rapid recovery.
- Treat cybersecurity like storm response: plan, practice, and restore service quickly after incidents.

- When attacks came, those utilities were blocked and the lights stayed on that day.
