Poll: How concerned are you about cyber attacks?

At 10:06, we'll be discussing America's preparations for cyber war.

President Obama recently signed a secret directive described in The Washington Post as "a broad and strict set of standards to guide the operations of federal agencies in confronting threats in cyberspace."

What are the threats? In a speech last month, Defense Secretary Leon Panetta said we should envision a "cyber-Pearl Harbor":

I know that when people think of cybersecurity today, they worry about hackers and criminals who prowl the Internet, steal people's identities, steal sensitive business information, steal even national security secrets. Those threats are real and they exist today.

But the even greater danger -- the greater danger facing us in cyberspace goes beyond crime and it goes beyond harassment. A cyber attack perpetrated by nation states are violent extremists groups could be as destructive as the terrorist attack on 9/11. Such a destructive cyber-terrorist attack could virtually paralyze the nation.
