The Effects Of The Snowden Leaks Aren't What He Intended
Originally published on Fri September 20, 2013 5:24 pm
An official assessment of the damage caused by news leaks about government surveillance programs suggests that terrorist groups are changing their communication methods in response to the disclosures, according to officials at the National Security Agency.
Shortly after former NSA contractor Edward Snowden leaked top-secret documents concerning the agency's foreign surveillance operations, Keith Alexander, director of the NSA, said the disclosures had caused "irreversible and significant damage." He ordered a thorough investigation into how the leaks occurred and what effect they would have on agency operations.
The damage assessment, which NSA officials describe as the biggest such effort ever undertaken in the U.S. intelligence community, is said to confirm Alexander's judgment.
Among the most noticeable initial effects of the leaks, however, may simply be that they prompted NSA leaders to divert agency resources from intelligence missions to security reforms and the investigation itself.
"We've devoted a lot of people to looking at the impact of what we think Snowden took, so it's people off task," says Richard Ledgett, the NSA official leading the leaks investigation.
Leaks May Prompt New Communication Methods
Intelligence officials say Snowden had access to a file-sharing location on the NSA's internal website and was able to copy secret documents stored there in part because he was responsible for moving the documents to a more secure location. Among those documents were memoranda and reports detailing how the agency monitors telephone and email data with a foreign connection.
The biggest concern, NSA officials say, is that foreign individuals or groups targeted for surveillance may now switch to more secure communication methods.
"If there is disclosure that NSA can do this thing or that thing, then they can take action to close that vulnerability. That denies us the ability to see the foreign intelligence threat," Ledgett says. "We're beginning to see that."
Assessing possible responses to the NSA disclosures, however, can be a complicated exercise. Even if terrorist groups change their means of communication, NSA surveillance programs may still serve a purpose.
"The question then becomes whether the existence of the program causes their operations to proceed more slowly, become more difficult, with less chance for real-time command and control," Ledgett says.
When Osama bin Laden learned the NSA was monitoring his satellite telephone, for example, he switched to sending messages by courier. The messages couldn't be intercepted, but the change meant bin Laden's communications became slower and more cumbersome as a result.
Expediting Planned Reforms
Another effect of Snowden's disclosures on NSA operations has been that agency leaders have chosen to expedite planned security reforms, as part of an effort to prevent future leaks. The agency has begun consolidating databases, moving them from separate repositories into large data centers where cloud analysis can be employed. The data are to be "tagged" with restrictions so that analysts not qualified or authorized to review the information will not be able to access it.
"We've had to do things that we had planned to do over the next three or four years and move them dramatically to the left," says the NSA's chief information officer, Lonny Anderson. "We haven't asked for additional resources. We've just said, 'We've got to do this.' So something gives, because we're not getting additional resources. And what gives, for us, is mission."
The NSA mission is intelligence gathering.
"We have to make sure we don't cross a line where we're so busy locking down the networks that we're not defending the nation," Anderson says. "That's the fine line we walk."
Such adaptations, however, are minor. The Snowden leaks and the resulting controversy have not yet prompted the NSA to rethink its whole surveillance operation.
"It hasn't caused any major right or left turns yet in the path the organization is taking," Ledgett says, though he notes that such changes would not be evident in the short term in any case.
To the disappointment of privacy advocates, there is little evidence that NSA leaders are reconsidering the propriety of their surveillance operations in light of all the objections raised in recent weeks.
"I haven't seen yet any willingness to reconsider the policies themselves," says Jameel Jaffer, director of the Center for Democracy at the American Civil Liberties Union.
"But in my view," he continues, "that's exactly what should be going on. The NSA should be part of this conversation about how broad government surveillance policies ought to be, and thus far all I've seen from the NSA is a kind of defensiveness about the programs that have been put in place."
Jaffer notes, however, that it is ultimately up to Congress and the White House to implement changes in the NSA's surveillance authority. On that, NSA leaders agree. "That's a policy decision," says Ledgett, "and we don't make that call. We operate within policy constraints."
AUDIE CORNISH, HOST:
From NPR News, this is ALL THINGS CONSIDERED. I'm Audie Cornish. "Irreversible and significant damage to U.S. national security" - those words from Gen. Keith Alexander, director of the NSA. He was describing the result of repeated leaks by former contractor Edward Snowden.
Since then, the agency has been considering whether it has to modify its approach to intelligence-gathering. NPR's Tom Gjelten recently raised that question with NSA leaders.
TOM GJELTEN, BYLINE: The Snowden leaks so upset leaders of the U.S. intelligence community that they felt compelled to launch a massive damage assessment, to find out what effect the disclosures would have on intelligence operations. One official says it's by far the biggest such effort ever undertaken.
At the NSA, the assessment has been led by Richard Ledgett, formerly the director of the agency's Threat Operations Center. He says the big concern is that potential terrorists, whose conversations were subject to NSA surveillance, might change to more secure communication now that details of the surveillance programs have been revealed.
RICHARD LEDGETT: If there's disclosure that, you know, NSA can do this thing or that thing or that thing, then they can take action to close that vulnerability.
GJELTEN: But even if terrorists do change their means of communication because of what they find out about NSA surveillance methods, the intercept program, Ledgett says, might still serve a purpose.
LEDGETT: The question then becomes whether the existence of the program causes their operations to proceed more slowly or more difficult, less chance for real-time command and control.
GJELTEN: For example, when Osama bin Laden learned the NSA was monitoring his satellite phone, he started sending messages by courier instead. The messages could not be intercepted, but the change meant bin Laden's communications after that were slower and more cumbersome.
Ledgett says there is one way the Snowden leaks have clearly affected NSA operations: The damage assessment itself has kept NSA employees from doing their regular intelligence work.
LEDGETT: We've devoted a lot of people to looking at the impact of what we think Snowden took. So it's people off task.
GJELTEN: Off task because NSA people got reassigned from intelligence work to investigative work. NSA resources have also been diverted into beefing up security at the agency to prevent future leaks. The agency is now tagging data with restrictions so that analysts aren't able to access the data unless they have the right training, for example.
Lonny Anderson, the NSA's chief information officer, says the change was already in the works before the Snowden disclosures, but it got speeded up. That move cost money the NSA had not planned on spending.
LONNY ANDERSON: We haven't asked for additional resources. We've just said, we've got to do this. So something gives because we're not getting additional resources. So at this point, what gives for us is mission.
GJELTEN: The NSA mission is intelligence gathering, now in danger of taking a backseat to security reforms, Anderson says.
ANDERSON: We have to make sure that we don't cross a line where we're so busy locking down the networks that we're not busy defending the nation.
GJELTEN: The Snowden episode, then, has forced the NSA to adapt. But Richard Ledgett, the chief leak investigator, says it has not prompted the NSA to rethink its whole surveillance operation - not yet, anyway.
LEDGETT: It hasn't caused any major right or left turns yet, in the path the organization is taking, but those things tend to take longer to resolve.
GJELTEN: So no redesign of the surveillance architecture; nor has there been any rethinking of the propriety of NSA surveillance activities in light of objections raised by privacy advocates. Jameel Jaffer, who directs the Center for Democracy at the American Civil Liberties Union, wishes NSA leaders paid more attention to the criticism of their surveillance operation.
JAMEEL JAFFER: I haven't seen yet any willingness to reconsider the policies themselves. But in my view, that's exactly what should be going on. The NSA should be part of this conversation about how broad government surveillance policies ought to be. And thus far, all I've seen from the NSA is a kind of defensiveness about the programs that have been put in place.
GJELTEN: Jaffer says it's ultimately up to Congress and the White House to consider changes in the NSA's surveillance authority. On that, NSA leaders agree. That's a policy decision, says Richard Ledgett, and we don't make that call.
