U.S. already at war in cyberspace, experts say — Government Computer News

SAN FRANCISCO — Cyber warfare is a reality, and the United States already has been engaged by a number of adversaries, a panel of experts said today at the RSA Security Conference.

“There is no question we are in the midst of a cyberwar,” added Dmitri Alperovitch, vice president of threat research at McAfee.

Because the war involves infiltration, espionage and sabotage rather than conventional weapons, it looks much like the Cold War waged by the United States and the Soviet Union in the post-World War II 20th century. But there are important differences, the panelists said. The Cold War was bipolar, with just two sides; there are many players in the cyberwar, and they each can have different goals.
