Abstract: A reliable and trustworthy network is essential for ensuring efficient data transmission, particularly because the widespread adoption of the Internet of Things (IoT) requires management of a large and diverse set of smart devices. In addition, privacy and security concerns in IoT systems, such as access authentication, authorization, and accounting, have become increasingly important. Software‐defined networking (SDN) offers a flexible and adaptive approach to network management and is a promising solution for addressing these challenges. Hence, this paper proposes a security mechanism that leverages the operational behaviors and characteristics of IoT devices to analyze their traffic flows using an SDN controller, thereby enhancing the overall security of IoT networks. The proposed architecture integrates a two‐factor authentication process to prevent unauthorized access while utilizing SDN‐based traffic monitoring to enforce fine‐grained access control. Experimental results show that the implemented solution assists the SDN controller in detecting abnormal behaviors and triggering mitigation measures, thereby minimizing disruptions to normal traffic flows in testing scenarios.
