Since the mid-1990s, discussion around the prospect of cyber war has become an increasingly hot topic. Many countries now place defense against cyber attacks at the highest level of priority in their national security strategies. The normative view of the threat is that, for those countries with a high level of dependence on information technology (IT) and networked infrastructure, a major cyber attack has the potential to level the playing field of military capability to devastating effect, whether it emanates from a hostile state or a non-state actor such as a terrorist group. Many seized upon events such as the cyber attacks against Estonian networks in 2007 as early salvoes in the new global cyber war. Critical perspectives, however, suggest that cyber activity is fundamentally different from activity in the physical world, and cyber attacks cannot be classified as acts of war as such. There is further suspicion that the level of threat has been overly militarized when its civil dimensions (such as cyber crime) may be more important, and that military and corporate interest groups may be hypersecuritizing the threat for their own gain. Much of the analysis has been conducted in the United States, the dominant military power and one of the most network-dependent countries in the world. Perhaps not surprisingly, many of the normative views of the military cyber threat point the finger of blame squarely at China and, to a lesser extent, Russia, suggesting a new Cold War. Throughout the debate, most accept that cyber threats are real and are growing in complexity and potential impact. Analyzing the nature of cyber threat in the military realm delivers a number of complexities. Much has been written about the legal aspects of “acts of war,” from both offensive and defensive perspectives, and how existing domestic and international regulation may be poorly designed to deal with cyber attacks. Governance of cyber capabilities and cyber defenses is proving to be a complicated affair, cutting across traditional boundaries of public/private, civil/military, and national/international. It is also the case that advanced states wish to be able to develop their own cyber capabilities for both intelligence gathering and strategic action against adversaries. How to deliver deterrence in a cyber context has been considered extensively, with parallels often being drawn with the rise of the nuclear threat in the 20th century. Analysis of case studies of what may constitute cyber attacks will be important in this fast-moving subject area. These case studies are examined from the perspectives of specific incidents in space and time and of specific technologies being used and how to counter them. Generally, cyber war is proving to be a very interdisciplinary subject, spanning technical, legal, sociological, and political realms. This makes it a vibrant new subject, but also a challenging one for academia, since the subject does not easily sit within a single identifiable department. Within the general domain of Security Studies, most of the socio-political analysis has been rooted either in conflict studies, especially the changing nature of postmodern conflict, or in securitization theory and the manner in which the threat is emerging from political discourse. But these are not the only directions from which the subject is being or should be approached.
Given the heightened interest in cyber threats generally, a number of books have emerged recently on the perceived threat of cyber war. Most of these are written by US authors and take a US-centric perspective on the issue, noting the fact that the particular dependence on networked infrastructure in the US military and in society in general could prove to be the country’s greatest weakness in the event of conflict. Many commentaries are also concerned with how the US government should position its cyber defense strategies, with many taking a critical view of progress made in this area. The normative view presented by most books in this field is that the threat of cyber war has gone beyond a hypothetical possibility and is present today. Clarke and Knake 2010, through the former’s position as a National Coordinator on Security, Infrastructure Protection, and Counterterrorism under four former US presidents, promotes this view and warns that US cybersecurity policy is not yet fit for purpose. Geers 2011, working from a position within NATO’s Cooperative Cyber Defence Centre of Excellence in Estonia, agrees that the threat is a major one to international security. Kramer, et al. 2009 presents a similar thesis with some policy recommendations, as does Rosenzweig 2013. Carr 2010 and the edited volume Latham 2003 provide some deep analysis of the nature of the cyber war threat and its complex intermingling with other threat vectors such as crime, activism, and terrorism. Denning 1998 (one of the earliest academic commentaries on cyber threats) and Healey 2013 provide a similar analysis of the changing nature of threat in this area, drawing some interesting parallels with information warfare through history. Green 2015 offers a multidisciplinary look at the question from the standpoints of law and international relations, suggesting that “warfare” is a useful term to cover a spectrum of aggressive cyber activities. Singer and Friedman 2014 emphasizes the importance of the coming “Internet of Things” in delivering new threats, and also the central significance of the United States and China to the global cybersecurity picture. Meanwhile, on the critical front, Rid 2013 challenges the normative view of cyber war, while Richards 2014 is similarly skeptical about whether any of the events seen so far constitute acts of war.
