More attacks like Sony are inevitable, and the Sony hack "was just a ham sandwich compared with what's coming," writes Kevin Maney of Newsweek:

Nobody knows how to stop these attacks, which will only get more sophisticated and more treacherous. This is the atomic bomb of our networked age—a looming disaster, and a genie that can never be stuffed back down. Cyberwar does not seem as tangibly destructive and terrifying as nukes, but give it time. It will.
