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.
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.
By using DHS as the middleman, the Obama administration hopes to bring the formidable overseas intelligence-gathering of the NSA closer to ordinary U.S. residents without triggering an outcry from privacy advocates who have long been leery of the spy agency's eavesdropping.
