The event was capped off with a talk by security expert Bruce Schneier, a fellow at the Berkman Center for Internet and Society at Harvard, and the chief technology officer at Co3 Systems.Schneier noted three trends he’s currently tracking. First, he said, we are losing control of our IT infrastructure. Second, cyber attacks are becoming more sophisticated. And third, he found that the increasing involvement of governments in cyberspace is blurring the lines between public and private data.“It used to be that our data was on our computers, under our control,” Schneier said. “But that is no longer true; our data is now on networks being run by Apple, Google, Amazon, Facebook, etc.” Schneier said this lack of control, which also extends to our devices, has great security implications.
