For OT systems, uptime is paramount. That's a hard rule that makes maintaining, upgrading, and securing them a complex struggle. Tomas "Data" Owens and James Cotter discuss how Tennessee is tackling the organizational and technical challenges that come with hardening OT systems across the state. Those challenges range from old technology (like RS-232 over Wi-Fi!?) to limited budgets. They talk about the different domains where OT appears and provide some examples of how the next generation of builders and breakers can start learning about this space.
