In the era of digital intelligence，regional network security construction should return to its essence. China should adopt capability thinking，and take actual combat as the goal，and shift from product-led to capability-led continuous construction of a security system. Compared with the United States and the European Union，our country still lacks a comprehensive network security capability maturity evaluation system that can be used as a unified standard for various regions. This is essential for a large country with a vast area，regional digitalization and network security developed unevenly. This evaluation system can not only promote the efficient and effective establishment of cybersecurity capabilities in various regions in accordance with unified standards and methods，but also promote regional collaboration in security data，security intelligence，security talents，security incident response，etc.，and achieve national-level information synchronization，unified scheduling，guard each other and fight together. In order to fill this vacancy，the National Engineering Laboratory for Big Data Collaborative Security Technology referred to relevant domestic and foreign research experience and proposed an evaluation model aimed at improving regional network security capabilities.
