Network Virtualization as a Security Force Multiplier—If Done Right
The digital environment of today requires a resilient and adaptable security architecture. With the growing dynamics of infrastructures that are increasingly distributed, the conventional perimeter-based defenses cannot keep up. That is where Network Virtualization appears as a potent architectural movement, which can enhance the security capabilities on the condition of having precision. Instead of simply an abstraction of physical elements, it redefines the application of control, visibility, and protection at each level of the network stack. Rethinking Security Boundaries Virtualized networks tear down physical boundaries that are hard and difficult to break with logically defined fragments. This displacement alters the process of trust assignment and its application. The security controls are not tied to the location of hardware anymore, but go with the workloads wherever they are applied. With this model, the network fabric itself becomes the protection, as opposed to a layer tha...
