Cyber threats against U.S. 'ramping up,' President Obama says

Cyber security threats against the United States are growing, President Barack Obama said before meeting corporate leaders to discuss rising concerns about hacking attacks emanating from China.

"What is absolutely true is that we have seen a steady ramping up of cyber security threats," President Obama said in an interview with ABC, noting that some threats were "state sponsored." "We've made it very clear to China and some other state actors that, you know, we expect them to follow international norms and abide by international rules," the President said. President Obama took the unusual step of meeting with corporate chief executives in the White House Situation Room, the secure site in the West Wing basement where the president meets with national security advisers during crises. The meeting included Honeywell International's David Cote, AT&T's Randall Stephenson, and Northrop Grumman's Wes Bush.
