Efficient and safe use of distributed information systems based on Grid and Cloud-computing technologies requires an assessment and optimization of their security level. For this purpose it seems appropriate to model the studied systems and their behavior under different working conditions. The paper presents an approach to modeling distributed systems in full-scale, simulation, virtual and analytical sense, and also describes the possibility of their simultaneous use in hybrid mode simulation. Such approach allows to investigate the behavior of distributed systems from different perspectives, taking into account features of the architecture, software, purposes of these systems and operation conditions. The paper also describes the mechanisms of the developed modeling software.
