Richard Esposito and Matthew Cole, NBC News: “When Edward Snowden stole the crown jewels of the National Security Agency, he didn’t need to use any sophisticated devices or software or go around any computer firewall. All he needed, said multiple intelligence community sources, was a few thumb drives and the willingness to exploit a gaping hole in an antiquated security system to rummage at will through the NSA’s servers and take 20,000 documents without leaving a trace. .. As a Honolulu-based employee of Booz Allen Hamilton doing contract work for the NSA, Snowden had access to the NSA servers via “thin client” computer. The outdated set-up meant that he had direct access to the NSA servers at headquarters in Ft. Meade, Md., 5,000 miles away. In a “thin client” system, each remote computer is essentially a glorified monitor, with most of the computing power in the central server. The individual computers tend to be assigned to specific individuals, and access for most users can be limited to specific types of files based on a user profile. But Snowden was not most users. A typical NSA worker has a “top secret” security clearance, which gives access to most, but not all, classified information. Snowden also had the enhanced privileges of a “system administrator.” The NSA, which has as many as 40,000 employees, has 1,000 system administrators, most of them contractors. [Note: Reuters reported NSA is eliminating 90% of its system administrators.]
