Abstract
The dynamical growth of cyber threats in IoT setting requires smart and scalable intrusion detection systems. In this paper, a Lean-based hybrid Intrusion Detection framework using Particle Swarm Optimization and Genetic Algorithm (PSO-GA) to select the features and Extreme Learning Machine and Bootstrap Aggregation (ELM-BA) to classify the features is introduced. The proposed framework obtains high detection rates on the CICIDS-2017 dataset, with 100 percent accuracy on important attack categories, like PortScan, SQL Injection, and Brute Force. Statistical verification and visual evaluation metrics are used to validate the model, which can be interpreted and proved to be solid. The framework is crafted following Lean ideals; thus, it has minimal computational overhead and optimal detection efficiency. It can be efficiently ported to the real-world usage in smart cities and industrial internet of things systems. The suggested framework can be deployed in smart cities and industrial Internet of Things (IoT) systems in real time, and it provides scalable and effective cyber threat detection. By adopting it, false positives can be greatly minimized, the latency of the decision-making process can be decreased, as well as the IoT critical infrastructure resilience against the ever-changing cyber threats can be increased.
