Your information is incorrect. The audit requirements at the CIA are just as stringent. There is no one who just gets to peruse data without a trail. The Security Technical requirements on any TS database systems are insanely complex and very thorough. Trust me—I’ve worked on similar DoD systems for years.
Now accessing data is dependent upon permissions, and there are some with “god” access, but even “god” is tracked. Not a byte is unaccounted.
I will defer to you on this, and will see if I can find the article that discussed in detail the difference between the two.
