Kim Zetter of Wired's national security blog, Threat Level, discusses the politics and science of the stuxnet virus that infected Iran's nuclear centrifuges.

Adam Segal argues that while Washington must engage Beijing in discussions about the rules of the road of cyberspace, more important will be efforts to work with allies and close friends in defining international norms of behavior.

Foreign governments, non-state actors, and criminal networks are targeting the digital networks of the United States with increasing frequency and sophistication. U.S. cybersecurity has made progress, but relies heavily on the private sector to secure infrastructure critical to national security.

Adam Segal says that regardless of the source of recent cyber attacks on U.S. firms, the United States must work independently and cooperatively with China to reduce their threat.

Adam Segal testifies before the House Foreign Affairs Subcommittee on Oversight and Investigations about Chinese cyber espionage and China's desire to reduce its dependence on the West for advanced technologies.

Richard A. Falkenrath discusses Stuxnet and the need for the United States to engage in offensive information warfare.

This New York Times article by William J. Broad, John Markoff and David E. Sanger examines the development and impact of the Stuxnet computer worm in undermining Iran's nuclear program.

Adam Segal and Cherian Samuel argue that both India and the United States have a stake in an internet that is open, global, and secure.

Increased connectivity allows for the spread of liberal, open values but also poses a number of dangers.

A favorite view of the Internet holds that the democratization of communications will bring about the democratization of the world.

The Pentagon recognizes the catastrophic threat posed by cyberwarfare, and is partnering with allied governments and private companies to prepare itself.

Cybersecurity expert Knake recommends the United States use international forums to promote mechanisms that address security concerns in cyberspace while ensuring the Internet remains open for the free exchange of ideas across national boundaries.

Robert K. Knake testifies before the House of Representatives Committee on Science and Technology on the role of attack attribution in preventing cyber attacks and how attribution technologies can affect the anonymity and the privacy of Internet users.

Google's decision to end censorship of its search content in China, and Beijing's response, appear to strike a balance between holding to principles and doing business, but U.S.-China clouds continue to gather, writes CFR's Adam Segal.

This initiative is the product of several reviews of cybersecurity strategies from multiple government departments, especially the Cyberspace Policy Review.

How well prepared are IT professionals within U.S. government agencies to respond to foreign cyber threats? Will government initiatives, such as the Comprehensive National Cybersecurity Initiative and the creation of the U.S. National Cybersecurity Coordinator role, be effective in addressing the challenges facing U.S. critical IT infrastructure? What is the impact of compliance on security within the federal IT environment?

The impact of the standoff between Google and China, argue Adam Segal and Robert K. Knake, may have less to do with censorship and more to do with the nature of technological development.
