Redefining deterrence in cyberspace: Private sector contribution to national strategies of cyber deterrence

ABSTRACT This article explores the nature and the desirability of private sector contribution to national strategies of cyber deterrence. The article starts by developing a variation of the concept of cyber deterrence, called RCDC deterrence, which is simultaneously restrictive, comprehensive, dynamic, and complemental. Second, it applies RCDC deterrence to identify and analyze specific areas of cyber deterrence that can benefit the most from private sector contribution. Third, the article cautions about the potential security, legal, and moral issues that could arise from such private contributions. Instead of offering definitive answers on these complex issues, the article ends by suggesting avenues for further research. The ultimate objective is to assist decision-makers in designing policies and regulations aimed at maximizing the benefits of public–private cooperation in cyber deterrence while mitigating its potential downsides.
