ABSTRACT
Threats are more diverse, viral and interconnected than at any time in history. The chapter begins by defining the basic threat categories: Crime, terrorism and war. It also reviews how the respective threat categories have been defined with regard to conduct that takes place in a purely physical context. It is impossible to appreciate the challenges confronting those charged with controlling internal threats (crime and terrorism) and external threats (war) unless one understands how traditional crime, terrorism and war mutate in cyberspace. The chapter explains, the definition of each threat category has for some time been settled with regard to conduct that occurs solely in the physical world. It explains the use of cyberspace can erode the distinctions between these three categories so that, for example, non-state actors may be able to engage in war and nation-states may be able to commit crimes.
