HIERARCHICAL LEVELS OF CONFIDENTIALITY OF INDUSTRIAL ENTERPRISES’ INFORMATION RESOURCES DEPENDING ON STAGES OF THE PRODUCTION LIFE CYCLE

The aim of the work is to create a methodology for constructing hierarchical levels of confidentiality of an industrial enterprise’s information resource depending on stages of the production life cycle. The base of the methodology is the Bell-Lapadula model “do not write below, do not read above”, applied in stages to the production life cycle. The novelty of the work is the proposed creative concept of using the model of access control to the industrial enterprise’s information resources in relation to the stages of the production life cycle. The result of the study is recommendations for applying the Bell-Lapadula model in constructing hierarchical levels of information resource confidentiality. In this case, the hierarchy of levels is determined according to the stages of the life cycle.
