Because security is central to humankind, societies and other organized groups, the notion has different meanings, depending on history, geography, culture and the nature of governments. Therefore it would be presumptuous and vain to pretend to lock the notion of security into a single dogmatic definition which would be immediately challenged by many others. A universal definition could be provided only by hard science which in that realm seems to be irrelevant or by a universal agreement among all the parties involved, still in limbo. Therefore, we will consider security from two empirical points of view linked by the notion of contract: political and economic. Security is not a scholarly discipline in itself with full recognition and a systematic presence in the traditional academic community. As a domain, security needs to be expanded far beyond the military and law enforcement domains, not just in order to counter current international terrorist activities in-depth but also to meet all the other requirements. Here we need historians, anthropologists, and others to do research and offer usable conclusions for a better understanding of security. If indeed we may assume that the demand for security has always existed, it is clear that it has dramatically expanded along with the evolution of human societies and the globalization of human activities. Modeling, elaboration of new models and the combining of models are needed. The initial exploratory workshop was dedicated to those matters. As a first step for further inquiry, we have limited ourselves to a general descriptive statement, not a normative definition. Security appears as “the ability to live, work and prosper on a daily basis. It is the main duty of the State to provide security both internal and external to each member of the collectivity/community of citizens”. Conversely, individuals who have agreed to enter into a society should assume their responsibility in order to contribute to their own security, the organization of which is provided by the State.
