Network and Distributed System Security (NDSS) Symposium 2024 · Day 2 · Mobile & Authentication
In the rapidly evolving landscape of 5G mobile networks, the transition to **Open Radio Access Network (O-RAN)** architecture presents both unprecedented opportunities and significant security challenges. Traditional cellular networks, with their closed and proprietary infrastructures, have long been a black box for security researchers. However, 5G's shift towards an open, software-defined, and interoperable paradigm allows for the integration of security-focused services directly into the network fabric. It is within this context that Haohuang Wen introduced **5G-SPECTOR**, a groundbreaking framework designed to detect Layer-3 cellular attacks within these emerging O-RAN environments.
