| 摘 要： | 针对云取证面临的主要挑战，分析云计算特性，提出了一种云取证模型。提出了持续性取证准备服务的部署、基于“迭代”的多轮次证据识别策略和分布式文件系统的多层级数据定位方法、基于“数据隔离”和“按需收集”策略的证据收集方法、基于云计算资源的综合性证据分析平台的建立。最后，结合云环境下的取证场景，分析了该模型的有效性。

| Abstract: | Aiming at the main challenges facing cloud forensics,cloud characteristics were analyzed and a cloud forensic model was proposed.In the model,the deployment of persistent forensic readiness service,multi-round identification strategy based on “iteration” and multi-level evidence location method for distributed file system,“data isolation” and “on-demand collection” strategies,and the establishment of comprehensive evidence analysis platform based on cloud resources were presented.Finally,the validity of the model was analyzed combining the forensic scene in the cloud environment. |
