Inside the Tabletop: What an Airport OT Incident Taught Us About Command, Cost, and Chaos

The team behind and inside Level Zero 2026's tabletop exercise breaks down what happened when an airport OT incident played out in real time. Derrik Oates and panelists from UPS, the Department of War, and the finance table walk through the ICS4ICS incident command framework, what it's like to be a first-timer when the pressure hits, why "keep your receipts" is real advice, and how to make sure exercise lessons actually change an organization. They also explain why the 2027 exercise becomes a dedicated full day.

Guests: Christian Harter (UPS); Donovan Tindill; Brad Willet (UPS); Daryl Haegley (United States Department of the Air Force) Host / moderator: Derrik Oates (UTSI)

The Cassandra Panel: OT Threat Intelligence from April to Now

Bryan Singer revisits an April threat briefing to ask what changed in six months, and the answer is a lot. Georgia Tech's Saman Zonouz shares research on thousands of internet-exposed PLCs, web-enabled controllers, shared firmware code across vendors, and exposed solar inverters. Daryl Haegley explains why threat intel has to start with knowing what's inside the fence, and Brad Willet brings the asset owner's view: stray contractor routers, insider risk, and why no newsletter replaces a trusted network. Vivek dubbed it "the Cassandra Panel" for a reason.

Three veterans of critical infrastructure security trace how the field went from arguing that infrastructure was even a target to treating digital risk as an engineering hazard. Ginger Wright, Sarah Freeman, and Marc Sachs define cyber-informed engineering in plain terms, share real examples of consequences engineered out of a system, explain why adversaries already read your engineering documentation, and make the case that engineers don't need to become hackers to belong in this conversation. They close with why engineers should come to Level Zero.
