Toward Securing the 6G Transition: A Comprehensive Empirical Method to Analyze Threats in O-RAN Environments.

In this paper, we present a new methodology that enables the MITRE ATT&CK framework to objectively assess specific threats in 6G Radio Access Networks (RANs). This helps address new security challenges that arise in the transition to open RANs. We analyze the O-Cloud component within the O-RAN ecosystem as a representative example, wherein no individual threat class demonstrates complete security. The inherent modularity of our approach ensures great adaptability and allows it to be applied to various other components within this system. This allows us to effectively detect and combat threats, thereby ensuring the resilience and security of future communication networks.
