From the Casebooks of . . .

In a field with few design principles ("defense in depth"? separate duties?), few rules of thumb, no laws named after people more influential than Murphy, no Plancks or Avogadros to hold Constant, and little quantification of any sort (we count only bad things), it appears the best we can do right now is to tell stories.

Over (enough) beer we conjure up lightly anonymized war stories about late-night phone calls, scary devices, hard-to-find bugs that exploiters somehow found, the backups that didn't, stupid criminals, craven prosecutors, cute hacks ("but don't try this at home"), and pointy-haired bosses. . . . There will be a few of these in this talk, but also some cautionary tales and parables—isomorphs of the Old Stories demonstrating human frailty and that the Law of Unexpected Consequences operates most strongly near the intersection of Bleeding Edge and Slippery Slope. Also, just a bit about the future.
