There is actually a way of gaming these types of systems.

Basically what NSA has is a complicated risk/benefit evaluation system. Very similar situation to banks deciding on a new loan. And unsurprisingly NSA came to the same technology as an answer to the problem, expert systems.

The way to game these types of systems is to spoil the risk/benefit evaluation. Easiest way is to beef up your defences, especially logging and hostile forensics. Or then ruin the benefit by organizing your processes so that you have very few secrets to begin with.
