The world's largest Internet search company and the world's most powerful electronic surveillance organization are teaming up in the name of cybersecurity.
Under an agreement that is still being finalized, the National Security Agency would help Google analyze a major corporate espionage attack that the firm said originated in China and targeted its computer networks, according to cybersecurity experts familiar with the matter. The objective is to better defend Google -- and its users -- from future attack.
Google and the NSA declined to comment on the partnership. But sources with knowledge of the arrangement, speaking on the condition of anonymity, said the alliance is being designed to allow the two organizations to share critical information without violating Google's policies or laws that protect the privacy of Americans' online communications. The sources said the deal does not mean the NSA will be viewing users' searches or e-mail accounts or that Google will be sharing proprietary data.
The partnership strikes at the core of one of the most sensitive issues for the government and private industry in the evolving world of cybersecurity: how to balance privacy and national security interests. On Tuesday, Director of National Intelligence Dennis C. Blair called the Google attacks, which the company acknowledged in January, a "wake-up call." Cyberspace cannot be protected, he said, without a "collaborative effort that incorporates both the U.S. private sector and our international partners."
But achieving collaboration is not easy, in part because private companies do not trust the government to keep their secrets and in part because of concerns that collaboration can lead to continuous government monitoring of private communications. Privacy advocates, concerned about a repeat of the NSA's warrantless interception of Americans' phone calls and e-mails after the Sept. 11, 2001, terrorist attacks, say information-sharing must be limited and closely overseen.
"The critical question is: At what level will the American public be comfortable with Google sharing information with NSA?" said Ellen McCarthy, president of the Intelligence and National Security Alliance, an organization of current and former intelligence and national security officials that seeks ways to foster greater sharing of information between government and industry.
On Jan. 12, Google took the rare step of announcing publicly that its systems had been hacked in a series of intrusions beginning in December.
The intrusions, industry experts said, targeted Google source code -- the programming language underlying Google applications -- and extended to more than 30 other large tech, defense, energy, financial and media companies. The Gmail accounts of human rights activists in Europe, China and the United States were also compromised.
So significant was the attack that Google threatened to shutter its business operation in China if the government did not agree to let the firm operate an uncensored search engine there. That issue is still unresolved.
Google approached the NSA shortly after the attacks, sources said, but the deal is taking weeks to hammer out, reflecting the sensitivity of the partnership. Any agreement would mark the first time that Google has entered a formal information-sharing relationship with the NSA, sources said. In 2008, the firm stated that it had not cooperated with the NSA in its Terrorist Surveillance Program.
Sources familiar with the new initiative said the focus is not figuring out who was behind the recent cyberattacks -- doing so is a nearly impossible task after the fact -- but building a better defense of Google's networks, or what its technicians call "information assurance."
One senior defense official, while not confirming or denying any agreement the NSA might have with any firm, said: "If a company came to the table and asked for help, I would ask them . . . 'What do you know about what transpired in your system? What deficiencies do you think they took advantage of? Tell me a little bit about what it was they did.' " Sources said the NSA is reaching out to other government agencies that play key roles in the U.S. effort to defend cyberspace and might be able to help in the Google investigation.
These agencies include the FBI and the Department of Homeland Security.
Over the past decade, other Silicon Valley companies have quietly turned to the NSA for guidance in protecting their networks.
"As a general matter," NSA spokeswoman Judi Emmel said, "as part of its information-assurance mission, NSA works with a broad range of commercial partners and research associates to ensure the availability of secure tailored solutions for Department of Defense and national security systems customers."
Despite such precedent, Matthew Aid, an expert on the NSA, said Google's global reach makes it unique.
"When you rise to the level of Google . . . you're looking at a company that has taken great pride in its independence," said Aid, author of "The Secret Sentry," a history of the NSA. "I'm a little uncomfortable with Google cooperating this closely with the nation's largest intelligence agency, even if it's strictly for defensive purposes."
The pact would be aimed at allowing the NSA help Google understand whether it is putting in place the right defenses by evaluating vulnerabilities in hardware and software and to calibrate how sophisticated the adversary is. The agency's expertise is based in part on its analysis of cyber-"signatures" that have been documented in previous attacks and can be used to block future intrusions.
The NSA would also be able to help the firm understand what methods are being used to penetrate its system, the sources said. Google, for its part, may share information on the types of malicious code seen in the attacks -- without disclosing proprietary data about what was taken, which would concern shareholders, sources said.
Greg Nojeim, senior counsel for the Center for Democracy & Technology, a privacy advocacy group, said companies have statutory authority to share information with the government to protect their rights and property.
