> How can you prove a negative?

I think in science you cannot "prove a negative" because you cannot observe all the events in the system (the universe).

But if you can observe all events in a system (Amazons data access logs) I think you can "prove a negative" by proving that the data was not accessed.



So employee A who should access data sees it and than tells employee B who shouldn’t.

Breached and now you lied to Congress. You can’t control everything that happens in your company.


Agreed, once data passes via human-human communication its not possible to observe 100%.


I think it's a logical fallacy to assume you can "observe all events" in any non-trivial system, particularly where there are humans on the edges.
