The First Cyber Battle: Bletchley Park and the Dawn of Digital Warfare

• In Event: Diffusion of Military Innovation: Causes and Consequences

Abstract

The study of cybersecurity in international relations suffers from two biases. A novelty bias conceives of cybersecurity as a primarily technological problem without precedent. A militarization bias conceives of it as a newly destructive form of warfare. While historical case studies have long been invaluable for understanding war on land, at sea, and in the air, it would seem that there is little history to inform our understanding of cyber warfare. In fact, however, history can and should be leveraged in cyber studies, but this requires a reconceptualization of the strategic nature of cybersecurity. Cybersecurity is better understood as the conduct of intelligence by computational means. Its essential strategic features, moreover, can already be seen in the cryptologic contest of World War II. The case of Bletchley Park is rightly one of the most famous episodes in intelligence history, but it also represents a unique confluence of computing theory, computing machines, and computing bureaucracy. This article deduces six conditions for successful cyber operations and shows how Bletchley Park realized all of them. The computational infrastructure of cybersecurity has changed radically in the decades since, to be sure, becoming more complex and involving more diverse actors, all at unprecedented scope and scale. Yet the strategic logic remains familiar, even as sociotechnical complexity makes the conditions for success more difficult to meet. Scholars can better understand the role cybersecurity today by examining the growing importance of deception and intelligence in the history and practice of international relations.
