Richard Clarke has been on the cutting edge of terrorism and cyber issues for quite some time.  He served more than 30 years in government and was the first White House official tasked with taking charge of U.S. cybersecurity policy.  He’s written eight books, half fiction, half non-fiction and his latest book, ‘The Fifth Domain: Defending Our Country, Our Companies and Ourselves in the Age of Cyber Threats’ was written with Robert Knake, who served as director for cybersecurity policy at the White House from 2011-2015.  Today both men serve as cybersecurity consultants, advising corporations and investors on cyber-related issues.
