Cyber Blockades is the first book to examine the phenomena of blockade operations in cyberspace, large-scale attacks on infrastructure or systems that aim to prevent an entire state from sending or receiving electronic data. Cyber blockades can take place through digital, physical, and/or electromagnetic means. Blockade operations have historically been considered acts of war, thus their emergence in cyberspace has significant implications for international law and for our understanding of cyber warfare.

The author defines and explains the emerging concept of “cyber blockades” and presents a unique comparison of blockade operations in five different domains—on land, at sea, in the air, in space, and in cyberspace—identifying common elements as well as important distinctions. Alison Lawlor Russell’s framework for defining cyber blockades, understanding how they occur, and considering the motivations of actors who employ them is applied with in-depth analysis of the cyber attacks on Estonia in 2007 and on Georgia during the 2008 Georgia-Russia War.

Blockade operations have occurred in cyberspace and will doubtlessly be used again in the future, by both state and non-state actors alike, because of the unique advantages of this type of attack. This book offers recommendations for policymakers contemplating or confronted by such attacks. Cyber Blockades is also a must-read for scholars and students of security studies, terrorism, substate groups, and the future of warfare.

In a very short time, individuals and companies have harnessed cyberspace to create new industries, a vibrant social space, and a new economic sphere that are intertwined with our everyday lives. At the same time, individuals, subnational groups, and governments are using cyberspace to advance interests through malicious activity. Terrorists recruit, train, and target through the Internet, hackers steal data, and intelligence services conduct espionage. Still, the vast majority of cyberspace is civilian space used by individuals, businesses, and governments for legitimate purposes.

Cyberspace and National Security brings together scholars, policy analysts, and information technology executives to examine current and future threats to cyberspace. They discuss various approaches to advance and defend national interests, contrast the US approach with European, Russian, and Chinese approaches, and offer new ways and means to defend interests in cyberspace and develop offensive capabilities to compete there. Policymakers and strategists will find this book to be an invaluable resource in their efforts to ensure national security and answer concerns about future cyberwarfare.

Cyberattacks are one of the greatest fears for governments and the private sector. The attacks come without warning and can be extremely costly and embarrassing.

Robert Mandel offers a unique and comprehensive strategic vision for how governments, in partnership with the private sector, can deter cyberattacks from both nonstate and state actors. Cyberdeterrence must be different from conventional military or nuclear deterrence, which are mainly based on dissuading an attack by forcing the aggressor to face unacceptable costs. In the cyber realm, where attributing a specific attack to a specific actor is extremely difficult, conventional deterrence principles are not enough. Mandel argues that cyberdeterrence must alter a potential attacker’s decision calculus by not only raising costs for the attacker but also by limiting the prospects for gain. Cyberdeterrence must also involve indirect unorthodox restraints, such as exposure to negative blowback and deceptive diversionary measures, and cross-domain measures rather than just retaliation in kind.

The book includes twelve twenty-first-century cyberattack case studies to draw insights into cyberdeterrence and determine the conditions under which it works most effectively. Mandel concludes by making recommendations for implementing cyberdeterrence and integrating it into broader national security policy. Cyber policy practitioners and scholars will gain valuable and current knowledge from this excellent study.
