Wide introduction and application of information technologies in management systems of the critical infrastructures (CIs) significantly increases the effectiveness of their intended use. Operative solutions rather complex of CIs management tasks are impossible without appropriate software (SW). At the same time, the lessons learned during the analysis of the effects of most major accidents and disasters involving various infrastructure entities indicate about underestimation of the contribution to the deterioration of the general reliability SW’s level. In order to eliminate this problem are propose to use a comprehensive approach to assessing the reliability of CI’s software management systems, taking into account different modes of its operation. The developed approach is based on an architectural representation of the functioning of corresponding software module and the effective implementation of the procedures for its control test.
