Wars of the future will be based on cyberattacks costing billions of dollars, destabilizing entire countries, and undermining democratic countries. Weaver and Johnson explain how cyber attacks are the single greatest threat to the national security of Canada and the United States. This book captures the use of cyber attacks in banking, elections, electrical grids, health care, and telecommunications. It is a fight over power, dominance, and control of the world stage. A must read for anyone interested in public administration and international affairs. Lorenda Naylor, Associate Professor and Director, University of Baltimore This is a timely book. The authors provide an excellent introduction to cyber security and how this important topic is handled in both the United States and Canada. The authors convey clearly how potential adversaries, whether state actors or non-state actors, employ different power tools in the cyber domain. These actors use asymmetric means in order to infiltrate and exploit cyber vulnerabilities in North America, most notably in the information domain. In presenting a simplified model and through a documented qualitative study, the book provides an overview to the reader on what to look out for and how to understand cyber security challenges in the United States and Canada. Tom Rųseth, Associate Professor of Intelligence Studies, Norwegian Defence University College Information is the core asset that ties a nations diplomatic, military, and economic capabilities together. Todays cyber technologies allow greater collection, analysis, and dissemination of that information than at any point previously in human history. The complexity of this new Cyber Domain allows for a tremendous increase in speed and capability, while also introducing new challenges that must be addressed. The barrier to entry for malicious actors, whether nation states or non-state actors, to commit harm against their enemies has been dramatically lowered. It has never been easier to commit harm to the interests of a nation and its people without the need for personal, physical risk than right now. Cyber Security Challenges Confronting Canada and the United States encapsulates the complexities of these challenges as they pertain to Canada and the United States. The authors examine how the Cyber Domain now influences and shapes those nations diplomatic, military, and economic policies. They define the new cyber domain in which nations must now operate, and illustrate various threats and risks to Canadian and U.S. interests. Also, they propose a new analytical model with which to examine these risks, and determine policy meant to mitigate them. This book is a must-read to help one understand the complexities of the cyber domain, and how it now helps shape and define policy.
