Introduction to the theory of security

The article contains the base of theory of security based on of humanistic sociology. The main elements are: the definitions of basic concepts (security, danger, crisis), the determinants of personal security, strategies of creating security in the dimension personal, social and organizational. The proposed definition of security appears to considerably regroup and arrange knowledge in the field of security, stimulate in a new way the understanding of the notion of security, provides foundation for quantitative and qualitative research and in some measure allows for mathematisation of this field of knowledge.
