虚拟机系统安全综述

Survey on virtual machine system security

随着云计算的广泛应用,虚拟机技术得到了复苏和长足的发展,但同时也带来了新的安全威胁,因此对于虚拟机的安全威胁和防御的研究成为目前计算机安全界的研究热点。以目前广泛应用的虚拟机Xen为例,针对虚拟机的技术特征分析了所存在的漏洞和威胁,并从计算机安全学的角度提出了相应的防御和保护方法。较为全面地总结了目前国内外针对虚拟机安全各方面相关的研究成果,通过系统的比较分析,指出了目前存在的问题,探讨了下一步的研究方向。

With the widely spread of cloud computing,virtual machine technology revives and gets rapid development,meanwhile,new threats are also introduced.Researches on the threats and defenses of virtual machines have become a hot topic.This paper firstly analyzed the vulnerabilities and threats of virtual machines,taking Xen as an example.Secondly,it introduced the defense and protect methods which put forward to improve the security.Furthermore,it reviewed the state-of-the-art methods on the virtual machine security.Finally the paper discussed the existed problems and presented future directions.
