Hello, I am a Security Engineer and deal with system security. I have an interest in Physics and wondered if the second law of thermodynamics applied to system security. My thought is... if you secure a [computer] system as much as possible (this can never be 100%) and leave it. Over time the entropy will increase and render that system vulnerable to attack. I mainly deal with computer and web application security. So my thoughts are in that context. What I'm trying to say here is that time will eventually render a security system useless no matter how secure it was originally. Any thoughts on this?
