Many security experts believe that the next world war will most likely involve cyberspace. Considering the numbers of hacks and cyber attacks we read about in the news, as well as attacks that impact critical infrastructure like hospitals and banks. All of these events carry real world impact. This activity is taking place in what the Pentagon calls “The Fifth Domain.” A new book called “The Fifth Domain: Defending Our Country, Our Companies and Ourselves in the Age of Cyber Threats” looks how we must think about protecting all of these critical elements. Richard Clarke, co-author of the book, joins host Dan Loney to discuss these considerations on Knowleddge@Wharton. Clarke spent 30 years in the U.S. government, including as White House counter terrorism coordinator under President Bill Clinton and George W. Bush. And he was the first White House Official to be in charge of U.S. cybersecurity.
