DEVELOPMENT OF THE METHODOLOGY FOR BUILDING SECURITY SYSTEMS OF INFORMATION RESOURCES IN INTERNET SERVICES

Abstract. Relevance of the topic. The article addresses the issue of developing security systems for information resources in internet services in the context of sociocyberphysical systems (SCPS). The purpose. A methodology for constructing a multi-layered information protection system is proposed, focusing on multimedia content used within social internet services. Results. The approach integrates advanced mathematical methods, including set theory, finite field theory, cryptography, and systems analysis. Special attention is given to hybrid threats that combine social engineering with attacks on SCPS components, which are typical of modern hybrid warfare. Conclusions. The results aim to enhance the protection of multimedia resources and improve resistance to targeted cyber threats.
