From Data Diodes to Zero Trust: Securing IT/OT Convergence

Critical infrastructure is converging OT and IT faster than ever. Central analytics, AI, and autonomous operations need OT data flowing out and verified commands flowing back in. At the same time, off-network IoT pushes data flows beyond the plant perimeter entirely. Data diodes have long secured that boundary, but in converged environments they become the bottleneck. So how do you speed up IT/OT convergence without compromising security? In this joint webinar, Patrick Lamplmair (CTO & Co-Founder, Tributech) and Hatteras Hoops (OT Security Lead, Europe, Booz Allen Hamilton) show how Zero Trust and data-centric security keep convergence moving without losing control. In this session, we discuss: 00:00 Agenda and speaker introductions 02:51 OT/IT convergence use cases and security challenges 07:42 How AI-powered attackers target converged OT/IT environments 15:21 Example: AI-assisted attack on a Mexican water utility 21:08 Defending the convergence zone: Purdue model, IDS, and monitoring 27:34 Security architecture models and the role of Zero Trust 30:26 Data diodes: strengths, limits, and operational reality 35:29 Why autonomous systems and LLMs need data-centric security 40:59 Data-centric Zero Trust vs. traditional architecture 43:17 Case study: how an oil and gas operator secured PCN writeback 46:58 Resources and next steps 48:48 Q&A 1:02:27 Closing remarks Want to read more?
