Annotation: The possibility of using of Identity and access Management system (IdM/IAM) is considered in the paper to automate users account and access rights management in Industrial Control System (ICS). The main feature of IdM/IAM system is that they require an individual approach and ongoing support when implemented in ICS. The results of the role-based access model development are presented for its implementation in IdM/IAM. An analysis of ICS safety has been carried out and the article provides a list of the information assets and information subjects representing the function, or roles, of industrial network users. A hierarchy of users roles and an access matrix (with possible rights) have been developed.
