Security requires a particular mindset. Security professionals — at least the good ones — see the world differently. They can’t walk into a store without noticing how they might shoplift. They can’t use a computer without wondering about the security vulnerabilities. They can’t vote without trying to figure out how to vote twice. They just can’t help it.
I totally get it. I can’t sit in a room with my back to the door. I always look for exits when I enter. I always watch for cars following me, take different routes to go places. They train you and it never leaves you.
