This descriptive legal analysis maps and evaluates a four decade legacy of communications security conceptualizations in E.U. law and policy, including four legislative proposals launched in 2013. As the first comprehensive historical analysis of its kind, the paper forwards a range of new scientific contributions in a time secure electronic communications are of historically unparalleled societal, economic and political relevance. Five communications security policy cycles are identified, and their ‘security’ definitions and scope are described. These cycles are: network and information security, data protection, telecommunications, encryption and cybercrime. An evaluation of the current E.U. ‘security’ conceptualizations illuminates the underlying values at stake, the protection offered in current regulations, the formulation of six research themes and an agenda for computer science, political theory and legal research. Despite constitutional values at stake such as privacy and communications freedom and a robust computer science literature, the paper observes a deep lack of conceptual clarity and coherence in E.U. security policymaking. It then concludes that the observed conceptual ambiguity has allowed powerful stakeholders to capture, or paint E.U. network and information security policies in any colour they like.
