"In the battle raging between offense and defense in cyberspace, Clarke and Knake have some important ideas about how we can avoid cyberwar for our country, prevent cybercrime against our companies, and in doing so, reduce resentment, division, and instability at home and abroad."--Bill Clinton
There is much to fear in the dark corners of cyberspace. From well-covered stories like the Stuxnet attack which helped slow Iran's nuclear program, to lesser-known tales like EternalBlue, the 2017 cyber battle that closed hospitals in Britain and froze shipping crates in Germany in midair, we have entered an age in which online threats carry real-world consequences. But we do not have to let autocrats and criminals run amok in the digital realm. We now know a great deal about how to make cyberspace far less dangerous--and about how to defend our security, economy, democracy, and privacy from cyber attack.
This is a book about the realm in which nobody should ever want to fight a war: the fifth domain, the Pentagon's term for cyberspace. Our guides are two of America's top cybersecurity experts, seasoned practitioners who are as familiar with the White House Situation Room as they are with Fortune 500 boardrooms. Richard A. Clarke and Robert K. Knake offer a vivid, engrossing tour of the often unfamiliar terrain of cyberspace, introducing us to the scientists, executives, and public servants who have learned through hard experience how government agencies and private firms can fend off cyber threats.
Clarke and Knake take us inside quantum-computing labs racing to develop cyber superweapons; bring us into the boardrooms of the many firms that have been hacked and the few that have not; and walk us through the corridors of the U.S. intelligence community with officials working to defend America's elections from foreign malice. With a focus on solutions over scaremongering, they make a compelling case for "cyber resilience"--building systems that can resist most attacks, raising the costs on cyber criminals and the autocrats who often lurk behind them, and avoiding the trap of overreaction to digital attacks.
Above all, Clarke and Knake show us how to keep the fifth domain a humming engine of economic growth and human progress by not giving in to those who would turn it into a wasteland of conflict. Backed by decades of high-level experience in the White House and the private sector, The Fifth Domain delivers a riveting, agenda-setting insider look at what works in the struggle to avoid cyberwar.

If there is a cybersecurity link to a specific technology, connection to a nation’s domestic or foreign policy, or application in some relatively unexplored area, Richard Clarke and Robert Knake are more than likely aware of it. The authors of The Fifth Domain were key policy advisers in past presidential administrations and consider their contributions to the American civic landscape to originate from their own self-perceived patriotism. Published earlier this year, the book’s title refers to the recent realization that cyberspace represents an additional primary domain of conflict that supplements the traditional four: land, sea, air, and space. Unlike the other four, however, the cyber field is vastly unexplored and brings several strategic challenges, many of which are, by the authors’ admission, currently unknown. And whether they are discussing a rich variety of topics that include the government’s role in cybersecurity versus the private sector’s, diplomacy in an ever-changing geopolitical landscape, or technological advances and their potential impact on attack vectors and response mechanisms, the reader can rest assured that the two have strong opinions about them. As the majority of cyber threats are unrealized, much of the book is devoted to instilling a sense of urgency in the American public – arguably overdue – and sharing approaches that are both reactive and proactive. While not comprised of the same types of vignettes that are included as part of other books, several sections of The Fifth Domain read like a horror story; alas, it is one that is based in true events of the recent past and others that could soon become a reality if left unchecked. Clarke and Knake, two policy-minded individuals, have chosen to write the book in a way that can be understood by a broad audience, both tech-savvy and otherwise. This approach is particularly effective in delivering the message to people within the cybersecurity or information technology industry, or perhaps more importantly, the general public who may not understand the role of cybersecurity in a modern strategic context. Each section of the book is presented in a logical progression, starting with the background devoted to the chapter’s main technology or theme (in some cases preceded by a brief anecdote) followed by the circumstances that are either helped or hindered by current conditions and bookended with the authors’ proposal for a solution. The predictability of the format lends itself well to readers who may not be able to read the whole book or the chapters in the order in which they are presented. The book also has its share of missed opportunities. Having spent a combined 35 years as public servants, Clarke and Knake unsurprisingly recommend solutions to many of the problems presented in the book that would be advanced by government efforts or integrate some form of regulatory action. Unfortunately, the weight of their words often falls short of providing a persuasive argument when marred by their bias and reluctance to present dissenting opinions substantively. Passionately preaching to the choir may sell books, but it does little by way of encouraging a badly-needed dialogue that considers all viewpoints of the debate. I hope that readers have a strong enough sense of critical thinking to be able to challenge the authors in areas in which multiple worthwhile solutions exist, including those with which Clarke and Knake would presumably disagree.
The Fifth Domain by Richard Clarke and Robert Knake is a book that delves into the growing threat of cyber attacks and what preventative measures can be put into practice to fight them. When I first started reading this book, I was interested to find out what the “Fifth Domain” was. There have been four major threats that the Pentagon have been concerned about when it comes to the safety of the United States. Those four domains of conflict are attacks from land, sea, air, and space. Russia and China are the two biggest threats for the United States for cyberattacks. Other countries including Iran and North Korea have been seen as threats against the United States as well. Russia was all over the news for their meddling in the 2016 election, and it has been accepted as fact at this point of time by most Americans. China has a similar ability to Russia when it comes to their resources for cyberattacks. China has “the ability to disrupt the U.S. natural gas pipeline system” (Clarke & Knake, pg. 272). Clarke and Knake do a great job of delving into all of these issues and discussing what changes can be made.
