You might be misunderstanding High Security.
A system is high security because of conflict - much like the high security zone in Baghdad - but those high security zones are still very dangerous.
From the Wiki:
The point being that "High Security" isn't addressing your personal safety concerns.
That is my understanding.
I agree that it is counter-intuitive.
I think you are projecting here. That is definitely NOT what it was originally supposed to mean. And probably well you know it. Higher Security was always intended as a label for "Safer".
