Knowledge based security

The greatest violence in the world is ignorance. In western society today we positively celebrate ignorance and "convenience" along with a half-baked notion that "AI" can run systems and defend us. The greatest threat is not zero-day it is zero-understanding.

One of the most profound security investments you can make is in education, to understand what your systems are doing and how they work. You cannot get this from proprietary products like Microsoft because their profit model relies on you not understanding how it works.
