The field of National Intelligence and Defense for a Cyber Espionage Specialist doesn't exist per se, it would have to be acquired from the inside after acquiring your conventional Cyber Security Specialist for the relatively measly CIA.
How much innovative product and $$ am I hacking for them? How much oil and ore am I relocating? Cyber warfare is very real. The Nation can laugh at some petty super board of directors for Harvard and dozens of special universities and tech schools. My last legitimate degree is a Masters in cyber espionage. With what may as well be an IQ of 300+ it would take me literally hours to build fail proof firewalls for routes (that have totally altered the global network's infrastructure on a nightmarish scale) that would take trillions of years worth of algorithmic computation to trace, even with hundreds of petaflops. Who the hell else is going to be capable of doing that for the U.S.? No one.
Can't afford to play fair in this world.
