[目的/意义]云计算的应用使得学术信息资源的存储和开发利用形态发生了变革,进而对其安全及保障也产生了显著影响,厘清这些影响有助于安全保障工作的开展,进而推进云计算在学术信息资源管理中的应用。[方法/过程]从保障主体、安全边界、保障模式和安全威胁4个方面对云环境的影响进行分析。[结果/结论]与传统IT环境相比,云环境下安全保障主体变得多元、安全边界变成动态边界、保障模式趋向集中化和安全威胁日益复杂化,这也对安全保障的组织提出了新的要求。 [Purpose / Significance] The application of cloud computing has led to changes in the storage and development and utilization of academic information resources, which in turn have had a significant impact on their safety and security. Clarifying that these impacts are conducive to the development of safety and security efforts and further promoting the development of cloud Application of Computing in Academic Information Resource Management. [Methods / Processes] Analyze the impact of the cloud environment on the four aspects of security subject, security boundary, security model and security threats. [Results / Conclusions] Compared with the traditional IT environment, the security assurance subject in the cloud environment becomes diversified, the security boundary becomes a dynamic boundary, the security mode tends to be centralized, and the security threat is increasingly complicated. This also presents the security guarantee organization New requirement
