Cutting-Edge Perspective of Security Analysis for Xen Virtual Machines
Virtualization and cloud computing is rapidly changing the enterprise landscape with enterprises and even individual users opting for cloud based solutions. With the large number of benefits that it provides it also increases security risk and needs immediate attention owing to its wide adoptability. The authors present in this paper an analysis of two attacks on virtual machines which run on xen hypervisor concentrating on insider as well as outsider intruder. In xen, pygrub is the commonly used bootloader for domU, but posses most of the security breaches. They present a DoS attack that occurs due to the inherent behavior of pygrub.
