IoT-based physical security systems: Structures and PSMECA analysis

The article presents the results of studies of the physical security system in the infrastructure facility of a region. The following results have been obtained: structural and functional decomposition of the physical security system for the regional infrastructure has been performed; engineering solutions for the implementation of the standard functions for the subsystems of the research object have been developed; a set-theoretic model of the failure occurrence in the context of the study of the physical security system has been developed. An example of PSMECA table is suggested.
