Relevance. The rapid development of sixth-generation (6G) mobile networks and the integration of artificial intelligence, the Internet of Things (IoT), cyber-physical systems, and cloud and edge computing necessitate new approaches to detecting and countering cyber threats. The wide variety of modern threats creates a need for intelligent protection systems capable of continuous monitoring, threat classification, assessment of adversary capabilities, and the adaptive formulation of defensive actions. The subject of the study comprises methods and models for constructing an intelligent system to detect and counter cyber threats in a 6G environment, utilizing neural networks, a multi-loop protection architecture, integrated security assessment, and error-resilient coding. The purpose of the article is to develop an intelligent multi-loop protection system for critical information infrastructure assets within a 6G environment; this system integrates neural network-based threat classification, adversary capability assessment, matrix analysis of interrelationships between resources, threats, and infrastructure elements, and an integral assessment of the current level of cyber resilience. Results obtained. A structural model for an integrated threat classifier combining CNN and RNN/LSTM architectures is proposed; application areas for neural networks in cybersecurity are systematized; a conceptual model for an intelligent multi-loop protection system is formulated; an approach to assessing adversary capabilities based on computational, temporal, and financial resources is formalized; and the procedure for calculating an integrated security metric is defined. A comparative assessment of protection mechanisms was conducted based on a set of characteristics. Conclusion. The proposed approach ensures a comprehensive combination of intelligent threat detection, multi-layered protection, and quantitative assessment of the current security status. For the post-quantum component of the system, it is advisable to focus on standardized and promising code-based and lattice-based cryptographic mechanisms, supplemented by error-correcting coding. Such an architecture establishes a foundation for an adaptive system to counter cyber threats in 6G networks and critical infrastructure facilities.
