Generative Adversarial Networks for Robust Anomaly Detection in Noisy IoT Environments

The Internet of Things (IoT) enables us to collect and process vast amounts of data in real time. However, the security of IoT devices and networks is highly susceptible to cyber attacks that threaten data integrity and service availability. Furthermore, due to the diverse nature of data collected from numerous nodes in IoT systems and the disturbances occurring within them, detecting anomalous activities and compromised nodes is considerably more challenging than in conventional computer systems. Therefore, it is crucial to develop robust and dependable anomaly detection methods to identify and remove malicious and/or unwanted data, which ensures their exclusion from IoT-powered applications and data analytics. To achieve this, this paper proposes a Generative Adverserial Networks (GAN)-based anomaly detection for IoT systems. The proposed model enables the autoencoder - using the adversarial training of GAN - to learn a better representation of IoT data, making it robust against noisy and changing environments. Based on experiments with real-world IoT datasets, the proposed framework has shown to improve the accuracy of detecting malicious traffic in IoT and surpass state-of-the-art anomaly detection models.
