In the first in-person interview Edward Snowden has conducted since his arrival in Moscow in June, Barton Gellman reports:

Snowden recounted another set of conversations that he said took place three years earlier, when he was sent by the NSA’s Technology Directorate to support operations at a listening post in Japan. As a system administrator, he had full access to security and auditing controls. He said he saw serious flaws with information security.

“I actually recommended they move to two-man control for administrative access back in 2009,” he said, first to his supervisor in Japan and then to the directorate’s chief of operations in the Pacific. “Sure, a whistleblower could use these things, but so could a spy.”

That precaution, which requires a second set of credentials to perform risky operations such as copying files onto a removable drive, has been among the principal security responses to the Snowden affair.
