"We Have Root is the latest collection of essays by security and privacy expert Bruce Schneier. He explores a wide range of cybersecurity, privacy, and real-world security issues that are as current as today's headlines. Written in clear and understandable terms, his essays explore the ever-expanding role of technology in national security, war, transportation, the Internet of Things, elections, and more. Rather than addressing technology experts. Schneier directs his writings to leaders, voters, and consumers. He challenges non-technical readers to question the status quo to make better security decisions and investments. As the internet and other technologies have become commonplace and fundamental to society, it is necessary to understand how these work and how they affect our everyday world. Today, social media is essential to public discourse. The web is vital for commerce. Even more critically, the Internet now affects the world in a direct and physical manner. In the near future, the Internet will enable pervasive surveillance at unprecedented levels. The book's essays originally appeared in numerous publications, including the Atlantic, the Wall Street Journal, CNN, the New York Times, the Washington Post, Wired, and others."-- Back cover.
