Defense Official: New Anti-Leak Measures at NSA

A top defense official says the National Security Agency is implementing new security measures because of the disclosures by former NSA-systems-analyst-turned-fugitive Edward Snowden.

Deputy Defense Secretary Ashton Carter says systems administrators like Snowden must now work with another colleague when accessing sensitive, compartmented intelligence. That's the kind Snowden leaked to the media, revealing that the agency was gathering millions of U.S. phone records and intercepting some U.S. Internet traffic.

Speaking at the Aspen Security Forum in Colorado, Carter says they are implementing a "two-man rule" everywhere systems administrators have "elevated" clearance to read sensitive information. Access to data will be limited as well instead of storing so much on a single server.
