Abstract: Due to the open network environment，complex information system and widespread social concern, major event faces increasing network security risks. The traditional plugin network security protection is more and more difficult to adapt to the increasingly complex network security situation of major event. Based on the network security assurance work of 2022 Beijing Winter Olympic Games and 2022 Beijing Winter Paralympic Games, this paper systematically sorts out the main characteristics of network security assurance for major event, puts forward a new generation network security framework, and analyzes the structure, characteristics and models of the framework in detail. The “zero accident” in the network security assurance work of Beijing Winter Olympic Games and Beijing Winter Paralympic Games shows that the framework can effectively guide the network security assurance work for major event, and provides a successful model for network security assurance work for major event.

Key words: network security, new generation network security framework, major event assurance, Beijing Winter Olympic Games, network security capability system

摘要： 重大活动因开放的网络环境、复杂的信息系统、广泛的社会关注而面临与日俱增的网络安全风险，传统的外挂式网络安全防护越来越难以适应日益复杂的重大活动网络安全形势.以2022年北京冬奥会和冬残奥会网络安全保障为背景，系统梳理了重大活动网络安全保障的主要特点，针对性地提出了新一代网络安全框架，并对该框架的结构、特点以及模型进行了详细分析.北京冬奥会和冬残奥会的网络安全保障工作“零事故”说明，该框架能够有效指导重大活动网络安全保障工作，为重大活动网络安全保障工作提供了成功样板.
