This article explores, from a legal perspective, the possibility of states taking responsive measures that enhance their cyber defence capabilities. Responsive cyber defence (RCD) is seen as a middle-path solution for states around which a clear and robust framework can be constructed. The authors only consider RCD as an option for states, and will avoid drawing any conclusions for the private sector. After defining RCD, the authors will address the deployment of RCD activities from both the international and domestic law perspectives in order to assess their feasibility and to determine their legitimacy.
