Fatma Ahmad Bazargan, Chan Yeob Yeun, Mohamed Jamal Zemerly · International Journal for Information Security Research · 2013
Virtualization is an emerging technology which provides organizations with a wide range of benefits.But unluckily, from a security standpoint, functionality often takes precedence over a main area like security, leaving security to be retrofitted in later.This paper mainly emphasizes on several security threats that exists today in a virtualization environment.However, the main contribution of the paper lies in highlighting the notable types of virtualization, its security threats and hypervisor deployment models.To start with, we will further our understanding of the state of knowledge for the latest virtualization technology, the role of the hypervisor and the two different types of virtualization architectures.We will then provide an in-depth explanation about the publicly adopted forms of virtualization and discuss the benefits and drawbacks that accompany each of them.The paper will finally highlight several security threats that exist in a virtualized environment today and the state-of-the-art of open source virtual machine monitor deployment models.
