Declassified 1970 US DoD cybersecurity document still relevant
Just read a great article on Art Technica covering a 1970 DoD analysis of computer system vulnerabilities...
I like it for a couple of reasons, firstly that the analysis is precise and concise, abstracting away the irrelevant items and focussing on the immutable aspects that stay true over time. Secondly that the overview diagram is highly reminiscent of the approach we use at OSA. Judge for yourself :)
