The article presents a concept of a theoretical approach to threat monitoring in the environment of a modern organization. The dominance of non-deterministic situations, including the increasing complexity, diversity and dynamics of events and phenomena are all characteristic for this environment. This places increased demands on security systems, including threat monitoring systems. The presented concept includes an integrated signal perceiving model, organizational system model, a model for the qualitative evolution of the organizational system, and a spiral model for organizational systems development.?The research methods applied include analysis and criticism of literature, analysis and logical construction as well as heuristic approaches: the “new insight” and analogical transfer method. The deductive and enumerative induction method were also applied in tandem.
