On Why Heads Should Roll at the NSA

Why’d Ya Have to Do It Evil Genius? » Balloon Juice:

"One of Snowden’s superpowers cited in that NBC story is the ability to “impersonate” high-level officials. This is a garden-variety capability that a lot of users with administrative access have. I have it in a couple of different forms on systems that I manage for clients. From the point of view of security, it’s a necessary evil, and it needs to be carefully controlled and audited. Hype and spin notwithstanding, the huge trove of documents that Snowden extracted from the NSA isn’t evidence that he’s some kind of Lex Luthor who couldn’t be thwarted by mere mortals. Instead, it shows that NSA’s controls were weak, and the NSA’s leadership needs to be held accountable"

If your sysadmins can impersonate anyone on a top secret network without any audit trail being generated and with no warning bells going off then you have to think it is a systemic failure and there needs to be several folks lose their jobs.
If I had written, or designed, this system I would be ashamed of myself.
If I was in charge of managing the folks that run it or wrote it I would be expecting to be fired about now.
If the system was generating usable audit trails and nobody was following up that is a level of dereliction of duty that one could argue it rises to criminal behavior, in particular 18 USC § 793 - Gathering, transmitting or losing defense information
