Abstract: Currently, China’s critical information infrastructure (CII) faces significant threats, including statesponsored cyber attacks and supply chain disruptions. This research aims to systematically analyze the key technological frameworks and development trends in CII security protection, assess China’s current technological capabilities and core bottlenecks in this domain, and propose development strategies and implementation pathways aligned with national conditions. Focusing on key technology clusters such as dynamic active defense, intelligent analysis and response, and resilience architectures, the study explores their synergistic application mechanisms and integration points with existing policies. The study seeks to provide critical technical support and policy recommendations for enhancing the security resilience and compliance of CII.

Key words: critical information infrastructure (CII), security protection, frontier technologies, zero trust architecture (ZTA)
