IIoT Security Using Industrial Identity Management System

The rapid expansion of Internet of Things (IoT) devices in industrial settings has revolutionized business operations, and enhanced efficiency and automation. However, this increased connectivity also introduces significant security challenges. This paper explores the critical importance of IoT security within industrial identity management frameworks. The paper examines emerging security threats targeting industrial IoT deployments. It emphasizes the importance of proactive threat intelligence, anomaly detection, and continuous monitoring to detect and mitigate real-time security breaches. The paper proposes a robust authentication mechanism, authorization policies, and centralized identity repositories to control device and user interactions effectively. The proposed approach uses the OAuth 2.0 authorization protocol to provide an efficient Identity and access management approach. The paper validates the proposed fundamental principles of identity management in industrial IoT ecosystems using the MIMIC IoT Simulator. The simulation shows that the design can work in principle and analyze the potential pitfalls.
