Securing the Benefits of Virtualization
Nemertes Research, Nov 2008, Pages: 5
Speaks to the IT manager concerned with security. Introducing virtualization into a data center increases the complexity of the environment and presents a new “threat surface,” the hypervisor and its associated management tools, to attack.
As the data center is transformed by virtualization, security lags. Worse, hurried attempts to retrofit traditional security solutions to the virtual servers leads to fragmentation and an erosion of the benefits of either security, virtualization, or both.
1. Security can’t be an afterthought in the transformation of the data center.
2. Companies are rapidly adopting virtualization, incented by the tremendous benefits it brings to static and inflexible data centers.
3. We must also ensure that the security solutions we choose do not sacrifice the benefits that we hoped to gain from virtualization.
4. In a flexible virtualized data center we need flexible security, built on common policies
Security professionals will need to examine new approaches to security, combining both physical and virtual security systems. Companies must secure these virtual systems without sacrificing the main benefits of virtualization: flexibility, portability and dynamic resource allocation.
