Abstract

With the proliferation of Internet of Things (IoT) technologies in urban environments, cities are increasingly deploying Edge processing nodes for urban sensing. This large-scale integration of Edge nodes and sensing endpoints raises significant security concerns. For instance, existing Intrusion Detection methods cannot scale well and do not consider the privacy and energy consumption implications that emerge when applied to those systems. In addition, the use of containerised applications managed by container orchestration platforms in these environments, while enabling diverse applications and allowing scanning of the container images, can still introduce vulnerabilities. This Chapter addresses the challenge of effectively detecting malicious activities in large-scale resource-constrained IoT systems. We introduce an unsupervised distributed learning solution employing Federated Learning (FL) for real-time anomaly detection across the IoT infrastructure. Our approach involves analysing Linux system call data through a Federated Learning Framework, significantly reducing the need for central data processing. The Chapter presents a comprehensive architectural overview of the system, its core components, and the methodology for deploying and updating anomaly detection models. It also provides the performance evaluation of our approach. Our results demonstrate that the size of the clients’ datasets and the use of pre-trained models play a significant role in the performance of FL models.
