Simulation model for researching the user behavior in distributed information computer systems

This article presents the development of a simulation model for the study of user behavior in distributed information computing systems, the development of a language model for describing user behavior, access rights are described, key information for compiling a profile of normal user behavior is revealed, a structural diagram and a mathematical model based on the method of analyzing abnormal user behavior are developed. based on an automaton model, which is created on the basis of the rules of unauthorized user actions, and contains signatures of anomalous user behavior, a formal representation of the transition table and a sequence of user actions is described, an automaton model of user behavior is developed, a generalized model of user behavior as a digital automaton is presented, as well as an algorithm diagram user actions. The study used the methods of information security theory, automata theory, pattern recognition theory and the theory of computing systems design.
