The concept of threat is a central point of reflection on security. Numerous publications have already attempted to identify and classify known hazards. The fundamental problem that arises in the course of this task is a large number of dangers potentially threatening to a person. It is therefore justified to ask why such a large number of threats are posed and whether their main sources can be identified. In the text, the author analyzes the relationship between terms of threat and risk and discusses various ways of defining them. Adopting various perspectives for analyzing, considering and classifying dangers allows observe elements which constitute their primary source. The model for classifying primary causes of threats includes three basic sources of dangers: dependence, coexistence and change.
