Abstract: The paper describes a method of dynamically control access to information resources in critical infrastructures, based on the user information profiles. Based on an analysis of the characteristics of differentiation of access to information resources in critical infrastructures, the indicators of a priori and contextual redundancy user rights are offered, which are used in the developed method. The method of Markov models to sequences of information resources used to build the information user profiles, and serial data analysis methods, used for verification of conformity of the activities of users formed profiles, are applied. Experimental estimation of the method is provided.

Keywords: access control, unauthorized access, critical infrastructure, user information profile, the cumulative amount.
