Modelling the System of Managing Information Risks in the Corporate Information System (p. 95 - 99)
The goal of the article lies in the study of possibilities of Petri nets for modelling the system of managing information risks in the corporate information system. The article offers to use fuzzy timed Petri nets with inhibitory links for modelling dynamics of permitting or forbidding access of users to the objects of the computer system. In the result of the study the article builds up a fuzzy timed Petri net with inhibitory links that allows modelling dynamics of the process of authentication and identification of the user, control of correspondence of differentiation of rights of access to information resources of the computer system. The prospect of further studies in this direction is the use of Petri nets for formation of fuzzy conclusions on effectiveness of the system of managing information risks in the corporate system.
Keywords: corporate information system, information risks, fuzzy Petri net, authentication and identification of users
