Exclusive - After 'cataclysmic' Snowden affair, NSA faces winds of change

FORT MEADE, Maryland (Reuters) - The U.S. National Security Agency has made dozens of changes in its operations and computer networks to prevent the emergence of another Edward Snowden, including potential disciplinary action, a top NSA official said on Friday, as a White House review panel recommended restraints on NSA spying.

Former NSA contractor Snowden's disclosures have been "cataclysmic" for the eavesdropping agency, Richard Ledgett, who leads a task force responding to the leaks, said in a rare interview at NSA's heavily guarded Fort Meade headquarters.
