云环境下电子取证研究

Research of Digital Forensics under Cloud Computing Environment

随着云计算业务的持续增长,与云计算相关的或者直接以云为目标的网络犯罪也不断增加。目前,云取证无论是技术层面还是法律层面,取得的进步还很小。对采取传统电子取证方法的取证人员来说,这些新兴的网络犯罪是一项重大挑战。文章首先分析了云取证的困难和挑战,然后指出了云取证的首要取证对象,最后提出了一套新的云取证方法、流程和技术。文章的研究成果能给电子取证人员调查涉云网络犯罪时提供借鉴参考。

With the sharp growth of cloud computing, cyber-crimes associated with cloud computing or directly targeted to cloud has increased greatly. Currently, the progress of cloud forensics is still very limited on both technical aspect and legal aspect. These emerging cyber-crimes are a great challenge to the investigators who still adopt traditional digital forensics methods. This paper analyzes the difficulties and challenges of cloud forensics, and then indicates the main forensics object for cloud forensics. Finally, a set of new cloud forensics method, is process and technique is proposed. This paper can bring references for the investigators in investigating cloud associated cyber- crimes.
