云计算环境下的取证问题研究

Research on Evidence Collection under Cloud Computing Environment

云计算是一种基于互联网的超级计算模式,它的快速发展给取证带来了一定的挑战。在云计算环境下,取证活动包括证据发现、证据固定及证据提取3个阶段。但云计算自身存在的安全风险,导致云计算环境下的取证活动亦面临一定的技术及法律问题。对于取证信息及手段方面的问题,可以采取数据迁移技术及入侵检测系统等手段加以解决。对于相关的法律问题,则可以采取完善相关法律法规、强化国际区际合作等途径加以解决。

Cloud computing is a kind of super computing model on the internet.The development of cloud computing brings some challenges to evidence collection.Under cloud computing environment,the evidence collection includes three stages：detection,fixup and scavenge.There are some safe risks in cloud computing,so collecting evidence under cloud computing environment will face some technologic and legal problems.As to the problems on evidence information and collecting measure,we can solve them by the technology of data migration and Intrusion Detection System.As to the legal problems,we can solve them by improving the legislation and strengthening the international cooperation.
