I came across this line in a scifi novel I was reading a while back. It got me thinking about the way we have become so dependent on information systems, even though we haven't entirely wrapped our brain around how to protect them.
People have been defending physical entities for thousands of years. We've got a pretty good idea how to do it (walls, locks, undisclosed locations, etc). But not so much when it comes to IT. Our need for it continues to expand, and our ability to protect it is scrambling to keep up.
Not quite sure what to do about that. Surely the answer is not to avoid being so dependent on IT systems.
