Advancing O-RAN Security: Integrated Intrusion Detection and Secure Slicing xApps

This paper introduces a novel cellular network security framework that leverages the O-RAN architecture. Central to this framework are two innovative xApps: the Intrusion Detection System xApp (IDSx xApp) and the Secure Slicing xApp (SSxApp). The IDSx xApp employs a self-attention enhanced recursive neural network autoencoder for efficient and precise intrusion detection. The SSxApp is designed for dynamic resource management, ensuring secure network slicing. This integrated approach significantly enhances network resilience against evolving wireless network security threats. This research provides valuable insights into the development and efficacy of these xApps, demonstrating their critical role in safeguarding next-generation cellular networks.
