OP here. I'm very interested in two things: thinking about new types of security tools and studying how different systems, especially those that are not computer related, are secured.

This repo is for people who also fall into the second camp and are curious about how prisons are secured, how museums are secured, etc. And the techniques used to do this systematically -- kill chains, failure analysis, and so on.

Happy to hear your feedback, and sorry if it's a bit disorganized!

But looks really good, thanks for creating and sharing it.

I like reading post mortem posts about security incidents too. There's a repo in GitHub that I follow: https://github.com/danluu/post-mortems

A great source for what to do, what to avoid, etc. Not only for security.
