"Conflict in cyberspace, as it turns out, is far more like conflict in the 'real' world than we've been told. If you're a diplomat, general, or elected official that cares about the implications of cyber warfare, be sure to read this book."
President Toomas Ilves of Estonia
"I've often complained that ... the biggest impediment to effective cyber defense in the United States was our failure to settle on the 'big ideas'--those macro-thoughts of law, policy and doctrine that should guide our cyber behavior. A Fierce Domain takes a giant step to meet this need by carefully (and entertainingly) laying out where we have already been on this journey. It turns out that we have a cyber history, after all, a history we can now put to work to guide our thinking and our future actions."
General Michael Hayden, Former NSA and CIA Director
"Don't think of A Fierce Domain as the first history book on cyber conflict, but as a practical guide to the policy questions that need to be answered to really address cyber security - not just in the U.S. but the world."
Jeff Moss, Founder of Black Hat and DEFCON security conferences
"This is an important book. I have not seen anything this thorough about the history, and without history we are poorly equipped to understand the future. In addition, the cases well support the three main conclusions: change is gradual enough for us to learn from the past; we have spent too much attention on cyber attack rather than exploitation; and we should beware of the popular myths about 'cyber wars' that obscure clear thinking about policy."
Joe Nye, Harvard University Distinguished Service Professor and Former Dean, Harvard Kennedy School
Few of the conflicts in A Fierce Domain "is a household name, though from the gripping accounts in Mr Healey's book many readers will feel they all should be ... Mr Healey's main message is to urge policymakers to be less secretive and more humble. Too many past attacks remain classified. Officials continue to burble the same warnings and assurances as they did 20 years ago; the public is left in the dark."
