The Internet of Things (IoT) is rapidly surfacing that spans all spheres of life. However, IoT devices are less secure due to limited computational capabilities, making them easy for malware for various attacks. Distributed Denial of Service (DDoS) attacks focused on the Internet of Things are among the most devastating attacks that have gained attention as the number of intelligent devices is ever increasing. Several security protocols and defensive solutions have been developed to improve the security scenario in IoT networks, the frameworks are tightly coupled. The heterogeneity of network traffic is frequently increasing, making it challenging to keep the defense solutions updated for zero-day attacks. Additionally, the tight coupling makes scaling, upgrading, and migrating defense systems challenging. The state-of-the-art solutions cannot address the increased need for on-demand services and security concerns inherent in today's Internet. This article presented a novel service-oriented architecture (SOA) for security frameworks that can be supplied to tenants and customers of tenants to mitigate these attacks. The objective of service-oriented architecture is to organise application components into a system of loosely connected services in order to build adaptable, dynamical operational procedures and adaptable applications that transcends enterprises and computing systems. The proposed Security conceptual paradigm SOA employs an SDN-based security mechanism to detect and mitigate DDoS attacks that occur in IoT computer networks. As interfaces to services for defensive systems, programming networks enable the implementation of security.
