As spy agencies are working to share data more securely, U.S. Director of National Intelligence James Clapper told a group of people at the Center for Strategic and International Studies that cloud computing will play a "major role" in defending U.S. agencies information, according to Bloomberg.

Clapper told the crowd that the cloud has a huge potential for promoting integration and getting savings, but it will come with a big requirement for security and privacy, according to the news source. He believes there will be some "notable changes" for labeling, tagging, monotoning and accounting over the next five years, especially after the 2010 WikiLeaks information leak.

Bloomberg said intelligence agencies are now trying to find a way to tag and label data separately. The aim is to allow better sharing among secretive agencies without losing the security that is needed. Clapper said the United States will need to spend more to look over these systems to prevent unauthorized entry.

The National Institute of Standards and Technology recently released the final version of its Guidelines on Security and Privacy in Public Cloud Computing. The guidelines said security, privacy and other requirements need to be laid out before any business or agency makes its way into the cloud.
