One of the approaches to modeling the route for spread of analysis of critical data in the hybrid area of cloud computing. Abstract: Use of cloud computing when forming the IT – infrastructure of the organization presupposes that the organization shall not control the aspects of security directly. There is need to guarantee conifdentiality of the data, when forming the architecture based on the cloud computing. The approach of modelling the data processing with the Petri nets in accordance with the requirements of the security policy of the organization allows to gain important information on the structure of multi-level system of access management in the hybrid cloud area. In the end it allows to follow dynamic behavior of processing critical data in the modelled system. Keywords: security models for the computer systems, cloud computing, public cloud, private cloud, hybrid cloud, security requirements, data confidentiality, modelling.
