Abstract:With the rapid development of Internet of Things (IoT) technology, the number of network devices has surged, making traditional intrusion detection systems (IDSs) less suitable for IoT environments due to their high consumption of computational resources. To address this issue, this study proposes a lightweight network intrusion detection system design method tailored for IoT environments, aiming to achieve efficient security protection with minimal resource overhead. The system integrates optimizations in deep learning models and improvements in feature extraction algorithms, employing a lightweight neural network architecture to reduce computational complexity. Furthermore, it leverages edge computing technology to migrate part of the processing tasks to local nodes, thereby minimizing data transmission latency and bandwidth usage. Experimental results demonstrate that the proposed system not only maintains a high detection accuracy but also significantly reduces memory and processor resource utilization, exhibiting superior real-time performance and energy efficiency compared to existing solutions. The primary innovation of this research lies in achieving high-performance intrusion detection in resource-constrained scenarios through model compression and the integration of edge intelligence, providing a feasible technical approach for IoT security protection.
