Overview of Cybersecurity Protection for Critical Information Infrastructure

This article delves into the current status, challenges, and related technologies of cybersecurity protection for critical information infrastructure (CII). It thoroughly analyzes the frequent occurrence of cybersecurity incidents worldwide and their severe impact on national security and public interest. Additionally, it elucidates the development trajectory of policy systems and technical standards for critical information infrastructure security across various countries. The article further explores key aspects of cybersecurity protection, including risk assessment, anomaly detection, security defense, and attack attribution. Although some progress has been made in the protection of critical information infrastructure, challenges remain, such as the complexity of attack methods, expanded attack surfaces, and the efficiency of attack attribution. Future research directions include the development of dynamic security strategies, the application of artificial intelligence technologies, enhancements in attack attribution techniques, international cooperation and information sharing, and the improvement of laws and policies.
