Model of Individually Group Assignment of Access to Hierarchically Organized Objects of Critical Information Systems Using Mobile Technologies

Abstract

The analysis of access control models currently used in information security systems (SPI) is carried out. Based on the analysis of the advantages and disadvantages of discretionary, authoritative and role models in the implementation of access of mobile systems of subjects with different needs and roles to hierarchically organized information objects of medical information systems (MIS), it is proposed to use access control based on a thematic - hierarchical policy. The methods of forming thematic grids that provide security control of information flows are proposed. The article offers methods for setting the reachability matrix for reading, writing, and executing different access subjects to access objects with monorubricated and multi-rubricated hierarchical thematic classification.
