  • The only system which is truly secure is one which is switched off and unplugged, locked in a titanium lined safe, buried in a concrete bunker, and is surrounded by nerve gas and very highly paid armed guards. Even then, I wouldn’t stake my life on it….An open security model is the easiest to implement . Simple passwords and server security become the foundation of this model. If encryption is used, it is implemented by individual users or on servers.
