Each day, more risks are created due to the increasing threats to our infrastructures and applications.
The current security solutions are no longer sufficient. They undermine the detection, prevention and visibility. To solve this problem, more and more security solutions are added (point-solutions).
Those security solutions all have their own interfaces and management platforms and that creates complexity. To achieve security simplification, we must work together so we can avoid integration overhead. The focus has to be on implementation and configuration which will have a positive effect on the level of security.
NFV versus SDN
Physical network components such as routers and firewalls make way for virtual editions. Hypervisors provide space for those virtual solutions. It is called Network Functions Virtualization (NFV). Boundaries blur, the virtual world takes over. Therefore, a shift in security policy is inevitable. We should ask ourselves what the hypervisor is and how it is protected.
Network entities operate through a control- (brains) and forwarding plane (muscles). Each stand-alone entity shall be programmed to carry out the network function (s) in a proper way. Software Defined Networking (SDN) provides a centralized control plane for your infrastructure. It programs instructions to the other network entities where the forwarding plane gets the instructions needed. Both techniques are all about virtualization, but they do not depend on each other. They create less network complexity and they can cooperate so security simplification can be achieved.
