The most common cyber attacks today—theft of government and/or commercial information and intellectual property—rarely have an immediate effect, such as a conventional military attack, said Deputy Defense Secretary Bill Lynn Thursday. But, they are enabling foreign competitors to steal the designs of US weapon systems, he said during a speech at the National Defense University in Washington, D.C. According to one recent estimate, such thefts have cumulatively cost the government and private sector a whopping $1 trillion, said Lynn. Attribution, or lack thereof, remains one of the biggest challenges in the cyber world, he said. “A missile comes with a return address. A cyber attack does not,” said Lynn. “We are getting much better [at identifying attackers], but it’s still a laborious process.” He used the occasion to unveil the Pentagon’s first cyberspace strategy, which attempts to outline both an offensive and defensive approach to protecting the Defense Department’s newest domain.
