New NSA Chief Calls Damage From Snowden Leaks Manageable

The newly installed director of the National Security Agency says that while he has seen some terrorist groups alter their communications to avoid surveillance techniques revealed by Edward Snowden, the damage done over all by a year of revelations does not lead him to the conclusion that “the sky is falling.”

Admiral Michael Rogers, who has now run the beleaguered spy agency and the military’s Cyber Command for just short of three months, described the series of steps he was taking to ensure that no one could download the trove of data that Snowden gathered -- more than a million documents. But he cautioned that there was no perfect protection against a dedicated insider with access to the agency’s networks.
