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)

摘要： 当前，关键信息基础设施(critical information infrastructure, CII)频繁遭受国家级网络攻击与供应链供给等严峻威胁.旨在系统分析关键信息基础设施安全防护的关键技术体系与发展趋势，评估我国在该领域的发展现状和面临的挑战，并提出符合我国国情的发展策略与实施路径.重点围绕动态主动防御、智能分析响应、韧性架构等关键技术群，探索其协同应用机制及与现行政策的契合点，为提升CII安全韧性与合规性提供关键技术支撑和政策参考.
