Systematization and management of access to data in a multifunctional digitalized system

The article is devoted to the formation of principles for constructing a data access system for a multifunctional digitalized system (MDS). The features of data generation and storage in the MDS are described. The importance of the unified information space of the MDS is shown and the peculiarity of the formation of a unified information space is described. Taking into account the peculiarities of the functioning of the MDS, the main tasks have been identified, the solution of which forms the model of access to data in the system. The dependence of the relevance of data on the assignment of those responsible for the data is indicated. The task has been set to ensure information security of a single information space. It is shown that the task of securing responsibility for data in the MDS is related to the task of disaggregating resources by type of activity attracted through functional areas. The dependence of MDS performance indicators on types of activities, functional areas and types of resources is shown. The paper examines mandatory, discretionary and role-based models of access to data. The shortcomings of access models in relation to the features of the MDS are identified. An architecture for regulating access to data using software modules and services is proposed. It is suggested to create a monitoring environment based on the construction of data sets determined through the performance indicators of the MDS.
