The data revolution has made our lives more convenient, but it’s also created vulnerabilities. Former Secretary of the U.S. Department of Homeland Security and The Chertoff Group Founder Michael Chertoff discusses his new book, “Exploding Data: Reclaiming Our Cyber Security in the Digital Age.” The use of digital tools has allowed us to generate a lot more data and to analyze it, altering our perception about the lines between public and private information. Chertoff talks about how we can avoid living in a world of ubiquitous surveillance and the need for greater protection of our cyber infrastructure. Finally, he calls for updates to policy and legal frameworks to reflect our new reality.
