Titov Dmitry Andreevich, Romashkova Oxana Nikolaevna

The article proposes a comprehensive model and methodology for selecting information protection and access control strategies for globally distributed corporate data processing systems in cloud environments with real-time requirements. In conditions of active digital transformation, Russian IT companies and corporate structures face the challenge of ensuring security while working with distributed data in cloud infrastructures. A multi-level access control architecture is proposed, including authentication, authorization, and audit mechanisms. A methodology for assessing information security risks and compliance with Russian legislation requirements has been developed. Practical recommendations for applying the proposed model are given using examples of Russian cloud providers and corporations with geographically distributed infrastructure. Based on the research conducted, key recommendations are formulated for selecting the optimal data protection strategy when using public, private, and hybrid cloud models, taking into account the specifics of the domestic IT landscape.
