Securing IoT Networks with SDN and NFV
(NFV) are two technologies that are becoming increasingly important for
the Internet of Things (IoT). Both SDN and NFV aim to improve the
flexibility and efficiency of networks, and they are being used to
address the unique challenges of IoT networks.
Difference Between SDN & NFV:
| SDN | NFV |
|---|---|
| SDN is a network architecture that separates the control plane and the data plane of a network. The control plane is responsible for making decisions about how data is sent through the network, while the data plane is responsible for forwarding data packets. By separating these two functions, SDN makes it possible to program and control networks more easily. | NFV is a technology that allows network functions, such as firewalls and routers, to be virtualized and run on standard servers. This makes it possible to create networks that are more flexible and efficient. With NFV, network functions can be deployed and scaled quickly, and they can be moved to different parts of the network as needed. |
| This is important for IoT networks because they often have to support a wide variety of devices and protocols, and the ability to program and control the network is essential for making sure that data is sent to the right place at the right time. | This is important for IoT networks because the number of devices and the amount of data that they generate can change quickly, and networks need to be able to adapt to these changes. |
Advantage Of SDN & NFV:
SDN and NFV helps to improve the scalability and flexibility of networks. IoT networks often have to support a wide variety of devices and protocols, and they need to be able to adapt to changing conditions.
SDN and NFV make it possible to create networks that can be programmed and controlled easily, and that can scale and adapt to changing conditions.
Another benefit of SDN and NFV for IoT is that they can help to improve the security of networks. IoT networks are often targeted by cybercriminals, and they need to be able to protect themselves against attacks.
SDN and NFV make it possible to create networks that are more secure by allowing network functions to be virtualized and run on standard servers, which makes it more difficult for attackers to access them.
In addition, SDN and NFV also help in reducing the total cost of ownership of IoT networks. By virtualizing the network functions and making it more programmable, allows for better utilization of the available resources and reduces the need for additional hardware.
