This is the purpose of governments; it is why we keep them around. There is no really defensible reason why the chemical, biological, radiological and nuclear industries are heavily regulated, but "cyber" isn't.
I mean sure technical solutions are available and do help, but to only look at the technical side and ignore the original issue seems like a mistake.
That means our society, our governments, our economic systems are security holes. Everyone saying the Bad Thing would happen did so by looking, not at technology, but at how our world is organized and run. The Bad Thing happened because all those actors behaved exactly as they are designed to behave.
