Flat Light

The world of information security has always had reference points – or ground truths – that, like physical features in a landscape, served as navigational features for practitioners and policymakers alike. As time has passed and the state of information security has become more uncertain, these features have eroded. As reference points, they are now either unhelpful (at best) or disinformative (at worst). A deep state of disorientation is now upon us - in privacy, in security, and beyond. This paper explains how we arrived at this point, and suggests what to do next.

A Rubicon

Optimality and efficiency work counter to robustness and resilience. Complexity hides interdependence, and interdependence is the source of black swan events.  The benefits of digitalization are not
transitive, but the risks are.  Because single points of failure
require militarization wherever they underlie gross societal
dependencies, frank minimization of the number of such single points
of failure is a national security obligation.  Because cascade
failure ignited by random faults is quenched by redundancy, whereas
cascade failure ignited by sentient opponents is exacerbated by
redundancy, (preservation of) uncorrelated operational mechanisms
is likewise a national security obligation.
