Sociological reflections on world disorder and new concepts of security

The aim of the paper is to offer a reflection on the transformation which the concept of security has been undergoing over the past few years. The ideal starting point for such a reflection is an analysis of some recurrent problems that are currently dominating the international scenario. The security debate no longer focuses exclusively on the political borders of nation-states, but also considers individual persons and communities. In a context characterized by increasing uncertainty and complexity, it is difficult: a) to separate the production of security from the production of risks; b) to differentiate between the functions of the various "agencies" set up to protect citizen and communities. Security, defining security and identifyng security strategies frequently stimulate political clashes and social conflicts. Supra-national institutions representing both states and citizen could be a valid solution, provided that security is conceived as a public asset and a collective responsibility to be persued in a framework of legality, wich derives directly from the autority of states and people
