>In todays news, Microsoft reactor management tools have been found to be signed using stolen keys after one reactor was forced into an emergency shutdown after hackers reduced the coolant flow rate
If you think MS would likely be worse at security than whatever other shop could be running your local reactor, I think you are either not being serious or you are getting confused by visibility and what the difficult things about IT are.
Trying to secure computers for 6 billion untrained randos, who will do unimaginably dumb things to the system you provide, which you have to keep super accessible while doing so, might not look very exciting, but is probably at least several magnitudes more difficult than securing a highly controlled, controllable and (I assume) strictly audited power plant.
