Threat vs. vulnerability

Inspired in part by Richard Bejtlich, I present Yet Another Horrible Information Security Analogy (YAHISA): A tale of bunnies and kitties.

Imagine a lush green field of grass and clover, where bunnies frolic and play. These are cute white bunnies, with pink eyes. And the occasional black bunny, which inexplicably costs more. The bunnies in this field have no natural predators. The wolves don't know about this field.

Now, picture a city cat that roams the streets, getting into fights, disappearing for days at a time. When it comes home, it's missing a little more of its ear, or occasionally needs to be stitched up. If it gets into a fight, sometimes it wins, sometimes it loses. It will eventually be run over by a car. Its bloated carcass will be poked by children with sticks.

The bunnies are vulnerable. The kitty is vulnerable, and has threats.
