"Cyber Persistence Theory is an important addition to our collective understanding of the dynamics of cyberspace and its implications for national security. It provides sound insight and excellent analysis on how we can meet the challenges of cyber in the hyper-connected, digitally driven world we find ourselves in today. Excellent work on a topic of increasing importance to all!" - Admiral Michael S. Rogers, USN (ret) former Commander, US Cyber Command and Director, National Security Agency (2014-2018)

"This timely new book is destined to go down as a major milestone in the development of new strategic thought for twenty-first century. With admirable clarity and powerful prose, the authors first dismantle the deterrence-focused paradigm that has so far guided US defense strategy in cyber space and then formulate a new organizing concept. Anyone interested in cyber security must come to terms with this new thinking." - Brad Roberts, Center for Global Security Research

"Michael Fischerkeller, Emily Goldman, and Richard Harknett have once again made an incredibly valuable contribution to the development of American cyber policy and strategy through the writing of Cyber Persistence Theory. The authors push its readership to think beyond classical deterrence theory to new concepts for engaging and defeating undeterred adversaries in cyberspace. In short, this book argues the need for change and to take more risk to close an increasingly larger risk in our defense and national security as well as our public safety posture as American citizens To do so, the authors argue will require not only persistent engagement, but a 'whole-of-nation plus' effort. A must-read for both national and cyber security professionals!" - Robert J. Butler, former Deputy Assistant Secretary of Defense for Cyber and Space Policy

"Time will tell whether cyberspace operations can have coercive effect, but it is unambiguously true that to date, nations have used cyberspace mostly to gain advantage in competing with other nations. Understanding how they do so is a new challenge that scholars of international relations would do well to take on, and this book is a superb point of departure for them." - Herb Lin, Hank J. Holland Fellow in Cyber Policy and Security, Hoover Institution, Stanford University

"This book helps to fill a crucial gap in strategic thinking about the fundamentals of cyberspace and sets out a clear course of action for the US government. It is a must-read for students, analysts and policymakers." - Max Smeets, Senior Researcher ETH Zurich, Center for Security Studies, and author of No Shortcuts: Why States Struggle Develop a Military Cyber-Force
