This chapter introduces the notion of ‘The New Security’ and explains the impetus for the book. The conceptual analysis of the notion of a new security is based on existing literature. Tribute is paid to previous work on the topic and the conceptual shift of the notion of security to a broader application is acknowledged. Five principles are identified as key to what is considered ‘the new security’. The nature of the research undertaken for the case studies that form the basis of the empirical chapters is defined and the remaining chapters of the book are outlined.
