US struggles to ward off evolving cyber threat

The United States is losing enough data in cyber attacks to fill the Library of Congress many times over, and authorities have failed to stay ahead of the threat, a defense official said. In a sobering assessment, the Defense Department's Jim Miller said more than 100 foreign spy agencies were working to gain access to U.S. computer systems, as were criminal organizations. Terrorist groups also had cyber attack capabilities. "Our systems are probed thousands of times a day and scanned millions of times a day," said Miller, principal deputy under secretary of defense for policy. He said the evolving cyber threat had "outpaced our ability to defend against it."
