Separation of protection and security means keeping different types of security measures separate. Protection is like a wall that keeps bad things out, while security is like a lock and alarm system that keeps the bad things away. Protection stops people or other bad things from entering, while security measures prevent bad things from happening even if they get inside. Protection is like a gate, while security is like an alarm that lets you know when something bad is happening. Protection helps keep you safe, while security helps make sure you stay safe.
