Abstract

A Hypervisor at the same time agrees a single system to run two or additional operating systems. To gather forensic proof of examined activities or attacks against the system, the evidence kept in logs of a system plays an important role. In this paper, we have analyzed logs, snapshots and also the network connectivity of guest and host operating systems. We have studied different virtualization systems and analyzed their logs, snapshots of hypervisor with dissimilar case studies to find the actions done on virtual systems. We have analyzed the deleted and formatted files information with the help of Encase forensic tool on some of the open source virtualization technologies like virtual box and qemu to ensure that the information existing in the system is always secure.

通过对托管虚拟化执行取证和网络分析来保护信息
Hypervisor同时允许一个系统运行两个或更多的操作系统。要收集针对系统的检查活动或攻击的取证证据,保存在系统日志中的证据起着重要作用。在本文中,我们分析了日志、快照以及客户机和主机操作系统的网络连通性。我们研究了不同的虚拟化系统,并通过不同的案例研究分析了它们的日志和虚拟机管理程序快照,以找到在虚拟系统上执行的操作。我们在一些开源虚拟化技术(如virtual box和qemu)上借助Encase取证工具对删除和格式化的文件信息进行了分析,以确保系统中存在的信息始终是安全的。
