Bottom Line
This technology development study presents a machine learning framework for detecting DDoS attacks in software-defined wide area networks, reporting high accuracy rates of >99.9%. However, the research lacks sufficient methodological detail, statistical validation, and real-world testing to assess its practical utility. While the cybersecurity application may be valuable for network infrastructure protection, this study does not relate to clinical practice or healthcare delivery. The absence of confidence intervals, comparison groups, and cost-effectiveness analysis limits the ability to evaluate the framework's true performance and implementation feasibility.

Abstract
Software-defined wide area networks (SD-WAN), empowered by software-defined networking (SDN) technology, offer unparalleled flexibility and efficiency in wireless communication. However, their integration introduces new security challenges, particularly in mitigating distributed denial of service (DDoS) attacks. In this paper, we propose an advanced security framework tailored to SDN-enabled SD-WAN. A dataset collected during experiments was used for training and testing the model's performance. Our framework leverages machine learning algorithms to detect and classify DDoS attacks targeting SD-WAN controllers, considering the environment's unique characteristics. We develop adaptive machine learning model capable of accurately discerning high-rate and low-rate DDoS attacks, enhancing the network's resilience against sophisticated threats. Results from controlled experiments show promise for real-world deployment, though further validation is needed. Our results highlight the framework's ability to adapt to dynamic network conditions and provide robust security for SDN-enabled SD-WAN. Our adaptive model integrates RF and DT explicitly for SD-WAN contexts, achieving 99.97% accuracy for high-rate attacks and 99.96% for low-rate attacks. Our QT-PCA preprocessing pipeline reduces dimensionality while preserving performance, and PACKET_IN event-triggered mitigation enables dynamic response. This method significantly enhances security solutions' accuracy, ensuring robust DDoS attack detection in SD-WAN environments. Additionally, by leveraging the SD-WAN architecture's efficiency, our approach optimizes network performance, underscoring its efficacy and practicality in enhancing security and efficiency.
