AI-Enabled IoT Intrusion Detection: Revolutionizing Security for a Connected World
The Internet of Things (IoT) revolutionizes connectivity, enabling innovative applications across healthcare, industry, and smart cities but also introducing significant cybersecurity challenges due to its expanded attack surface. Intrusion Detection Systems (IDSs) play a pivotal role in addressing these challenges, offering tailored solutions to detect and mitigate threats in dynamic and resource-constrained IoT environments. Through a rigorous analysis, this study classifies IDS research based on methodologies, performance metrics, and application domains, providing a comprehensive synthesis of the field. Key findings reveal a paradigm shift towards integrating artificial intelligence (AI) and hybrid approaches, surpassing the limitations of traditional, static methods. These advancements highlight the potential for IDSs to enhance scalability, adaptability, and detection accuracy. However, unresolved challenges, such as resource efficiency and real-world applicability, underline the need for further research. By contextualizing these findings within the broader landscape of IoT security, this work emphasizes the critical importance of developing IDS solutions that ensure the reliability, privacy, and security of interconnected systems, contributing to the sustainable evolution of IoT ecosystems.

Achieved Detection Accuracy in multi-class scenarios with CPS-IoT-PPDNN
This model for anomaly detection showcases high performance while maintaining fast training and real-time operational capability in CPS-enabled IoT environments.
Smart City IDS Deployment
In a smart city pilot integrating smart traffic and energy management systems, a distributed machine learning-based IDS using Random Forest and fog-edge analytics was deployed. It achieved a detection accuracy of 97.8% and a False Positive Rate of 2.1%, with a processing latency of 0.3 s per packet in fog nodes. This demonstrated how distributed IDSs reduce latency compared to centralized systems and how fog-edge coordination enhances scalability, though it requires robust node synchronization. The system filters malicious activity in real time, preserves service continuity, and protects public infrastructure and private households from evolving cyber threats.
