Similarities between nuclear reactors and computer security

This article offers one of the best explanations of how a nuclear reactor is built, what’s happened so far during the Fukushima reactor accident, and what safeguards are in place to prevent an even larger disaster. It turns out nuclear reactor architects and computer security architects have a similar mindset. Both use “Defense In Depth” to put up multiple layers of protection in case of disaster. If one system fails there are several others behind it as a contingency plan. It sounds like the accident has affected a few of the safeguards, but others are still working.
