Excellent info, thanks. "OT" vs "IT": "Operational Tech" (pipeline and safety-critical monitor and control) and "Information Tech" (payroll, email, other business stuff) ? I could only imagine trying to tell a large corporation that their "IT" authentication system can't be linked to the access card keys for the front gate, or whatever other physical security they might have in place. It doesn't matter if we can formally prove that a remote access system is sufficiently secure as to aloow engineers to operate valves and pumps from home... For inevitably, some months from now, a wildly insecure utility will be connected to that, and you lose the ability to reason about how to keep the streams from crossing.
