"Beware of the words "internal security," for they are the eternal cry of the oppressor."
I haven't read Voltaire but, I don't think he ever considered the issue of an "insider" problem in the cyber world.
"Security" from the Nancy Pelosi/Harry Reid Dictionary of Congressional & Senatorial English:
1. The state of being dependent, as for support.
2. a. Subordination to someone or something needed or greatly desired.
b. Trust; reliance.
3. The state of being determined, influenced, or controlled by something else.
4. A compulsive or chronic need; an addiction
