With an open architecture and interface, O-RAN is designed to build the next-generation RANs with intelligent control. It can provide a certain degree of flexibility and customization and allow new communication interfaces between network components (e.g., O-CU, O-DU) and Radio Access Network Intelligent Controllers (RICs). Moreover, it can work with real-time detection, response, and management with machine learning (ML) algorithms on applications (xAPPs). However, the open architecture and interface also significantly increase the possibility of being attacked. This presentation not only explores the current development of the O-RAN alliance in information security, but also integrates O-RAN and Software Defined Radio (SDR) to realize an experimental network and explores the possible threats of new network components and interfaces in this experimental environment. Finally, we would also discuss the implementation of information security-related xAPP on O-RAN to enhance the security of O-RAN.
