The U.S. government is expanding a cybersecurity program that scans Internet traffic headed into and out of defense contractors to include far more of the country's private, civilian-run infrastructure. As a result, more private sector employees than ever before, including those at big banks, utilities and key transportation companies, will have their emails and Web surfing scanned as a precaution against cyber attacks.
Under last month's White House executive order on cybersecurity, the scans will be driven by classified information provided by U.S. intelligence agencies — including data from the National Security Agency (NSA) — on new or especially serious espionage threats and other hacking attempts. U.S. spy chiefs said on March 12 that cyber attacks have supplanted terrorism as the top threat to the country.
