Abstract

The question of whether deterrence is achievable in or through cyberspace has sparked considerable debate among academics. Over time, arguments have evolved, further entrenching this discourse and moving it out of the mainstream spotlight. This article examines how recent armed conflicts in Ukraine and Gaza may reinvigorate discussions surrounding this issue. It emphasizes that cyber activities can indeed produce deterrent effects while also recognizing the necessity for a new terminology to accurately capture these effects. In cyberspace, traditional deterrent logics—such as deterrence by denial or punishment—along with core principles including credibility, communication, and cost-benefit analysis, do not uniformly apply due to the prevalence of non-state actors and the complexities of attribution. Moreover, cyberspace's unique characteristics, such as the influx of diverse actors and a broad spectrum of potential activities, have transformed the foundational principles of deterrence. This article concludes that cyberspace functions as a level playing field where both state and non-state actors can exert influence, leading to the emergence of new forms of deterrent effects. It reframes the concept of deterrence to align with the distinctive features of cyberspace, illustrating how cyber operations can significantly influence adversaries' actions.
