We have published and presented this paper at the *26th Conference on Innovation in Clouds, Internet and Networks and Workshops (ICIN)*. DOI: [https://doi.org/10.1109/ICIN56760.2023.10073509](https://doi.org/10.1109/ICIN56760.2023.10073509?ref=pragmaticslab.com)

ABSTRACT:  

*Software-Defined Networking (SDN) is a new paradigm in network architecture that improves scalability, flexibility, control, and network management by separating the control plane from the data plane. SDN controllers have a global view of the entire network and provide the ability to dynamically change traffic forwarding rules. However, Introducing SDN* 
*brings some new DDoS attack vulnerabilities, such as limited flow table capacity and single point failure of a controller.* 
*This paper proposes an approach that combines linear discriminant analysis (LDA) and a supervised self-organizing map (SOM) called LSSOM that enables to detecting suspicious packets to defend against DDoS attacks in real-time. Our experimental results show that using LSSOM achieves 98.2% accuracy and reduces the classification time by 73.5% compared to using supervised SOM only.*
