The national security of the United States depends on a secure, reliable and resilient cyberspace. The inclusion of digital systems into every aspect of US national security has been underway since World War II and has increased with the proliferation of Internet-enabled devices. There is an increasing need to develop a robust deterrence framework within which the United States and its allies can dissuade would-be adversaries from engaging in various cyber activities. Yet despite a desire to deter adversaries, the problems associated with dissuasion remain complex, multifaceted, poorly understood and imprecisely specified. Challenges, including credibility, attribution, escalation and conflict management, remain ever-present and challenge the United States in its efforts to foster security in cyberspace. These challenges need to be addressed in a deliberate and multidisciplinary approach that combines political and technical realities to provide a robust set of policy options to decision makers. The Cyber Deterrence Problem brings together a multidisciplinary team of scholars with expertise in computer science, deterrence theory, cognitive psychology, intelligence studies and conflict management to analyze and develop a robust assessment of the necessary requirements and attributes for achieving deterrence in cyberspace. Beyond simply addressing the base challenges associated with deterrence, many of the chapters also propose strategies and tactics to enhance deterrence in cyberspace and emphasize conceptualizing how the United States deters adversaries.

Cyberspace, where information--and hence serious value--is stored and manipulated, is a tempting target. An attacker could be a person, group, or state and may disrupt or corrupt the systems from which cyberspace is built. When states are involved, it is tempting to compare fights to warfare, but there are important differences. The author addresses these differences and ways the United States protect itself in the face of attack.

In a world of increasing dependence on information technology, the prevention of cyberattacks on a nation's important computer and communications systems and networks is a problem that looms large. Given the demonstrated limitations of passive cybersecurity defense measures, it is natural to consider the possibility that deterrence might play a useful role in preventing cyberattacks against the United States and its vital interests. At the request of the Office of the Director of National Intelligence, the National Research Council undertook a two-phase project aimed to foster a broad, multidisciplinary examination of strategies for deterring cyberattacks on the United States and of the possible utility of these strategies for the U.S. government. The first phase produced a letter report providing basic information needed to understand the nature of the problem and to articulate important questions that can drive research regarding ways of more effectively preventing, discouraging, and inhibiting hostile activity against important U.S. information systems and networks. The second phase of the project entailed selecting appropriate experts to write papers on questions raised in the letter report. A number of experts, identified by the committee, were commissioned to write these papers under contract with the National Academy of Sciences. Commissioned papers were discussed at a public workshop held June 10-11, 2010, in Washington, D.C., and authors revised their papers after the workshop. Although the authors were selected and the papers reviewed and discussed by the committee, the individually authored papers do not reflect consensus views of the committee, and the reader should view these papers as offering points of departure that can stimulate further work on the topics discussed. The papers presented in this volume are published essentially as received from the authors, with some proofreading corrections made as limited time allowed.

This book creates a framework for understanding and using cyberpower in support of national security. Cyberspace and cyberpower are now critical elements of international security. United States needs a national policy which employs cyberpower to support its national security interests.

A fresh and refined appraisal of today's top cyber threats

“We are dropping cyber bombs. We have never done that before.”—U.S. Defense Department official A new era of war fighting is emerging for the U.S. military. Hi-tech weapons have given way to hi tech in a number of instances recently: A computer virus is unleashed that destroys centrifuges in Iran, slowing that country’s attempt to build a nuclear weapon. ISIS, which has made the internet the backbone of its terror operations, finds its network-based command and control systems are overwhelmed in a cyber attack. A number of North Korean ballistic missiles fail on launch, reportedly because their systems were compromised by a cyber campaign. Offensive cyber operations like these have become important components of U.S. defense strategy and their role will grow larger. But just what offensive cyber weapons are and how they could be used remains clouded by secrecy. This new volume by Amy Zegart and Herb Lin is a groundbreaking discussion and exploration of cyber weapons with a focus on their strategic dimensions. It brings together many of the leading specialists in the field to provide new and incisive analysis of what former CIA director Michael Hayden has called “digital combat power” and how the United States should incorporate that power into its national security strategy.

The complexity of the twenty-first century threat landscape contrasts markedly with the bilateral nuclear bargaining context envisioned by classical deterrence theory. Nuclear and conventional arsenals continue to develop alongside anti-satellite programs, autonomous robotics or drones, cyber operations, biotechnology, and other innovations barely imagined in the early nuclear age. The concept of cross-domain deterrence (CDD) emerged near the end of the George W. Bush administration as policymakers and commanders confronted emerging threats to vital military systems in space and cyberspace. The Pentagon now recognizes five operational environments or so-called domains (land, sea, air, space, and cyberspace), and CDD poses serious problems in practice. In Cross-Domain Deterrence, Erik Gartzke and Jon R. Lindsay assess the theoretical relevance of CDD for the field of International Relations. As a general concept, CDD posits that how actors choose to deter affects the quality of the deterrence they achieve. Contributors to this volume include senior and junior scholars and national security practitioners. Their chapters probe the analytical utility of CDD by examining how differences across, and combinations of, different military and non-military instruments can affect choices and outcomes in coercive policy in historical and contemporary cases.
