Enhancing IoT Network Security Using SDN Controller and Blockchain Technology
Keywords:
SDN, Software-defined networkingAbstract
To beautify the security of SDN network In order to enhance the security of SDN (Software-defined networking) networks utilized within cloud environments, SDN has been upgraded, thus altering the standard procedure of the existing network. This study aims to implement an SDN-approved blockchain application on the cloud. Likely, the SDN controller ryu is employed for network management and customization. This review presents an overview of common security issues encountered with SDN when integrated with cloud environments. It introduces emerging ideas in the newly launched blockchain model and proposes reasons that support blockchain as a formidable security feature when solutions are deployed where SDN and cloud are interconnected. Given the significant increase in the amount of user data (private, enterprise, commercial, etc.) available online, this puts them at high risk from malicious users. Various security measures have been proposed and implemented to protect user data against undefined risks. Many of these solutions utilize traditional networking approaches that are intricate and challenging to manage. These approaches rely on the manual configuration of devices, causing policy conflicts that may compromise network security.
