But we need to use that as part of our default thinking, right? That we just need to be able to operate.

So many platforms, think a car or helicopter or airplane, when they first started automating them with computers in them to do automatic anti-lock braking, those kinds of ABS braking kinds of systems, people assumed that the outside of the car was untrusted, but inside the car is trusted.

DARPA ran a program called HACMS, the High Assurance Cyber Military Systems, that looked at cars and helicopters and understood that within the car there was no authentication or encryption.

Essentially, if someone was able to break into or have a cyber vulnerability in any one component of the car, they could easily take over almost everything in the car.

So a different mindset is, oh, let's protect one part of the car, the radio, from the tire pressure gauge.

That was not the mindset when DARPA began the HACOMS program.

And by now, that is the right way to build a platform that there's internal controls, multilayer defense, and ways that things are monitored.

Surprise is, by definition,
