I had the pleasure of hearing Admiral Grace Hopper[1] speak at an
ACM luncheon once. When she discussed security, she asserted that
there was no such thing as security which could not be breached.
The goal of security efforts should not be to make it perfect,
because you can't; any time you convince yourself you have that you
are simply fooling yourself and missing the vulnerabilities. In her
view the goal was to make the costs of breaching security higher to
the perpetrator than the benefits. Each obstacle in their way helps
tip the scales in your favor.
