To implement security in cloud platform the significance of virtualization can’t be neglected. The hypervisors, which is also known as virtual machine monitor, offer a handful of facilities to configure the virtual machines to redesign the communication channel through which they can interact with each other or with the internet. We have studied how the facilities of virtualization can be optimally used to secure the communication between virtual machines and internet in a private cloud infrastructure. In this regard, we have tried to enhance the communication mechanism through constructing a cloud infrastructure framework. This paper deals with the isolation of virtual instances to improve the private cloud security through prevention from spreading infections between virtual machines VMs & also between VM & internet. Moreover, our proposal focuses on the filtering of inflow and outflow traffic to and from the outside world through a dedicated VM of a host implemented in layered switching environment.
