The agency will also more carefully review the publication of books and articles by former employees.

The initiative comes as another of the nation's intelligence organizations -- the National Security Agency -- is reeling from the disclosure of information about two of its top-secret surveillance programs. Those programs were revealed by 30-year-old former defense contractor Edward Snowden, who is currently in Moscow and attempting to avert extradition back to the United States.

The Justice Department has also come under fire for its handling of leak investigations, with media groups objecting to the targeting of reporters for Fox News and the Associated Press.

In a speech in May, President Obama said "leaks related to national security can put people at risk."

“They can put men and women in uniform that I’ve sent into the battlefield at risk," Obama continued. "They can put some of our intelligence officers, who are in various, dangerous situations that are easily compromised, at risk. ... So I make no apologies, and I don’t think the American people would expect me as commander in chief not to be concerned about information that might compromise their missions or might get them killed.”
