Ted Koppel, Former ABC News Anchor & Author of "Lights Out"

Imagine a blackout lasting not days, but weeks or months. Tens of millions of people left in the dark without running water or access to grocery stores, banks, medical facilities. How will we survive?

According to veteran journalist Koppel, this isn't just a story line from a movie but a realistic scenario. A well-designed attack on just one of our nation's three electric power grids could cripple much of our existing infrastructure. And while our federal government is well prepared for natural disasters, there is no plan for the aftermath of an attack on our power system. Koppel examines those potential threats and advises on the best ways to avoid a cyberattack catastrophe.
