Thesis Title 

Strategic cyber defence: Shaping the operational environment 


Cyber security has evolved into a matter of national security. Consequently, nations are experimenting with how to defend national interests and enhance sovereignty in the digital domain. There is a growing consensus that strategic approaches to cyber defence must be based on some sort of deterrence. However, it remains unclear how states can communicate their capabilities and intentions credibly to deter cyber attacks. Therefore, this research project will investigate the efficacy of different communication activities in supporting cyber defence strategies.

A combination of rational deterrence theory and communication theory will make up the analytical framework that will be applied to historical data on governments' statements of their capabilities over the last decade. This examination will serve the project's primary objectives, which are to generate empirical and theoretical knowledge about how states communicate about their cyber capabilities, and to explain how communication can be used strategically and in different ways to enhance national cyber defence.
