Abstract: This paper designs a security protection system based on the continuous adaptive risk and trust assessment and security responsibility sharing model in accordance with the current network security needs of the meteorological big data cloud platform. With the protection of the meteorological big data cloud platform as the object, the five stages of security protection, including decisionmaking planning, defense in depth, monitoring and early warning, security response and security evaluation, are carried out around security management, security technology and security operation, which fully ensure the security operation of the meteorological big data cloud platform, and provide a new idea and new mode for the network security protection of the meteorological cloud platform in the future.

Key words: meteorological big data cloud platform, network security, adaptive concept, responsibility sharing, security operation

摘要： 针对气象大数据云平台存在的网络安全现状需求，设计一种基于持续自适应风险与信任评估、安全责任共担模式的安全防护体系，以保护气象大数据云平台为对象，围绕安全管理、安全技术和安全运营开展覆盖决策规划、纵深防御、监测预警、安全响应和安全评价5个阶段的安全防护，全面保障气象大数据云平台的安全运行，为今后气象云平台网络安全防护提供一种新思路和新模式.
