Abstract: [Purpose/Significance] In the era of big data, agricultural research institutions in China have begun to increase the investment in informatization construction to bring great convenience to scientific research and management, but corresponding information security issues have risen to the surface. Tasks such as relying on the network hierarchical protection and performing in-depth analysis of each weak link in the information system construction of agricultural research institutions to improve the information system security and avoid network security problems have been placed in a prominent position in the work of agricultural research institutions. [Method/Process] This article discusses the issue of strengthening the information security management of agricultural research institutions based on hierarchical protection 2.0. First of all, this article introduces the importance of hierarchical protection. Secondly, the difference between hierarchical protection 2.0 standard and h1.0 standard is analyzed. Thirdly, the system of network security management and the network security management technologies of Chinese Academy of Agricultural Sciences were analyzed in detail. Finally, it discusses and summarizes the effective strategies to strengthen the information security construction of agricultural research institutions.[Results/Conclusions] Taking the Chinese Academy of Agricultural Sciences as an example, this paper discusses its practices in detail, in the hope of providing reference for agricultural research institutions to carry out network security hierarchical protection.
