In Security at Extreme Scales, Eric Grosse argues, "Much of the security progress over the past decade has been at large-scale, finding and patching vulnerabilities in widely used applications or defending networks of millions of machines containing high-value data. The lessons there may help military systems, but for the very highest security needs such as NC3, we ought to return to basics and harden small-scale systems. And we ought to do it as a joint effort, even between adversaries."
