Operationlisation of Persistent Engagement and Defend Forward

Bachelor thesis | Security Studies (BSc)

In 2018, the US Department of Defense announced its new National Cyber Strategy. With other actors in cyberspace becoming increasingly aggressive and potent, this strategy is designed to establish the US as a capable and functional actor in the domain. This new national cyber strategy differs greatly from the previous deterrence-based approach, illustrating a major shift in strategic thinking. The US military has now moved away from deterring enemies through denial and cost imposition, and introduced two new concepts instead: Persistent Engagement & Defend Forward, PE/DF for short. As cyberspace has grown to be the backbone of modern society, this change is significant for both scholars and the rest of the world. Through a case study of the US military, this thesis aims to investigate how this new strategy influenced the manner in which the US military conducts cyber operations. The results of this research show that the US has become significantly more aggressive, pro-active,...Show moreIn 2018, the US Department of Defense announced its new National Cyber Strategy.

Through a case study of the US military, this thesis aims to investigate how this new strategy influenced the manner in which the US military conducts cyber operations. The results of this research show that the US has become significantly more aggressive, pro-active, streamlined, diverse in methods and in general capable in engaging with hostile actors in cyberspace.Show less
