Abstract: With the accelerating process of digital government construction, digital government network security is facing increasingly severe risks and challenges. This paper proposes a digital government network security assurance framework system by studying the existing network security-related assurance framework and capability evaluation models, and proposes the country's first systematic and executable provincial digital government network security index evaluation system. The current situation of digital government network security is objectively evaluated from four aspects of security management, security construction, security operation and security effect. Index evaluation work is of great significance to promote the iterative construction of network security defense system and continuously improve the level of digital government network security protection.

Key words: digital government, network security index, index evaluation, evaluation system, security assurance structure

摘要： 随着数字政府建设进程日益加快，数字政府网络安全面临日益严峻的风险和挑战．本文通过研究已有网络安全相关保障框架和能力评估模型，提出了数字政府网络安全保障架构体系，并在此基础上提出了全国首个体系化、可落地的省级数字政府网络安全指数评估指标体系，从安全管理、安全建设、安全运营和安全效果4个方面对数字政府网络安全现状进行客观评价．指数评估工作对促进网络安全防御体系迭代建设，持续提升数字政府网络安全防护水平具有重要意义．
