Virtualization requires a redefinition of security protocols especially for those deploying virtual servers and virtual networks. Because virtualization is a new technology, old models and methodologies for setting up the security of the IT environment have become moot. There are two main issues that need to be addressed in order to properly set up the security of virtual IT environments.
First, network defenses must be redefined and new network security features must be developed. Typical network security protocols involve filtering intrusive traffics that are perceived to be malicious. It is then barred from entering the network system thus protecting the integrity of the network infrastructure.
With virtual networks, this approach is not applicable. A network that has been virtually connected communicates with one another using the internal processes of the IT environment. It is possible then that the external network defenses would not be able to detect intra-virtual traffic and will not recognize malicious programs. This poses significant risk to the network and to the entire IT environment. It can corrupt the system from within. Luckily, some developers are researching for solutions that will bulletproof and secure virtual networks.
Secondly, developers must find a solution to secure hypervisors. Hypervisors are the chief programs that manage the different operating system in the virtual machine. It is a known fact that operating systems are the most vulnerable component of computers. Hypervisor is the main operating system and once it is attacked all the other operating system could crash. Developers therefore should create a technology that will increase the security features of hypervisors.
