Abstract: In recent years, cyberattacks targeting national critical information infrastructure systems have increased rapidly, intensifying the security situation increasingly severe. Cyberattacks exploiting vulnerabilities in weak defense systems have become a major threat to the security protection of critical information infrastructure. Under the increasingly complex cyberattack environment, building a coordinated defense mechanism has become especially important. This paper analyzes the evolution and progress of organizational management in the area of critical information infrastructure security both domestically and internationally, and proposes a series of improvement measures. These efforts aim to provide reference for the future development of organizational management systems in coordinated security protection for critical information infrastructure.

Key words: critical information infrastructure (CII), cyberattack, system security, coordinated defense mechanism, organizational management systems

摘要： 近年来，以国家关键信息基础设施系统为目标的网络攻击事件快速增长，形势愈发严峻，针对防御薄弱系统的网络攻击已成为关键信息基础设施系统安全防护工作的主要威胁.在日益复杂的网络攻击环境下，构建协同防护机制显得尤为重要.分析了国内外在关键信息基础设施系统安全防护方面的组织管理体系演变和进展，提出了一系列对策建议，旨在为关键信息基础设施安全防护管理体系的工作提供参考.
