xApps for DDoS Attacks Detection and Mitigation in 5G-V2X O-RAN Networks

In this demo, we present a 5G prototype designed to secure V2X communications by leveraging the concept of distributed applications (xApps) in 5G O-RAN. Based on the open-source srsRAN, our framework protects against DDoS attacks by implementing a dual-xApp strategy. The first xApp, called attack detection (AD) detects and identifies DDoS attackers in real-time, using deep learning. The second xApp, named resource control (RC), is executed dynamically to reduce the network resources of identified attackers. We show that our method effectively neutralizes malicious users by minimizing their impact on network performance while maintaining stable operations for legitimate users.
