  • Abstract:
  • Distributed Denial of Service (DDoS) attacks present significant challenges to Software-Defined Networks (SDN) and Internet of Things (IoT) environments, where dynamic traffic patterns make threat detection complex. Traditional Intrusion Detection Systems (IDS), which rely on static rules and signature-based techniques, often fail to detect evolving attack patterns, leading to high false positives and inadequate threat mitigation. This paper proposes a Hybrid Machine Learning-Based IDS that integrates Random Forest (RF) and Support Vector Machine (SVM) through a Voting Classifier to enhance detection accuracy and reduce false positives. The hybrid model leverages the strengths of RF in decision-making and SVM in boundary optimization to provide a more reliable and adaptive solution. To improve classification performance, extensive experiments were conducted using a labeled DDoS dataset (CIC-DDoS2019), applying preprocessing techniques such as feature extraction, normalization, and data augmentation to enhance data quality and balance. The hybrid model achieved 80% accuracy and demonstrated a 15% reduction in false positive rate compared to traditional IDS systems. Feature importance analysis highlighted critical indicators such as packet rate, flow duration, and source-destination interactions, which were key in distinguishing between normal and malicious traffic. The model’s adaptive learning capability and scalability make it suitable for securing modern IoT and SDN environments. The experimental results validate the system's effectiveness, and future work aims to enhance its adaptability to detect complex and evolving attack patterns, further improving real-time threat mitigation and overall network security.
