The Washington Post, citing documents it said were provided by Snowden, said the NSA’s concerns about insider threats were aimed at “anomalous behavior” of agency employees with access to top secret data. The account cited NSA concerns about “trusted insiders who seek to exploit their authorized access to sensitive information to harm U.S. interests.”
The NSA concerns were outlined in top-secret documents provided to the Senate and House intelligence committees in February 2012, well before Snowden emerged this summer as the sole source of massive new disclosures about the agency’s surveillance operations. The Post released only 17 pages of the entire 178-page budget document, citing conversations with Obama administration officials who voiced alarms about disclosures that could compromise intelligence sources and methods.
Shawn Turner, director of public affairs for the Office of the Director of National Intelligence, who has taken the lead in responding to the Snowden disclosures, did not immediately respond to a request to discuss the budget figures.
It was not clear from the Post’s reporting how many of the 4,000 potential insider threats were ultimately investigated or how many posed serious breaches of security. Steven Aftergood, head of a project on government secrecy at the Federation of American Scientists in Washington, questioned whether many of the reported 4,000 possible leaks were credible cases.
Referring to previous reports that the NSA’s classified work force totals nearly 40,000, Aftergood said, “It would be hard to believe that one in every 10 NSA employees is a possible threat.” He suggested that many cases might be caused by internal warnings arising from minor internal protocol errors or mistakenly accessed documents.
But Justice Department prosecutions in recent years of several former NSA staffers have shown the agency taking a toughened stance in cracking down on possible leaks. “In any case, a number that large is striking,” Aftergood said.
