5G registration tracking based on logdata

5G mobile communication has brought many new services and features to existing mobile communications. The diversity and scalability of the provided services and devices have raised many new vulnerabilities and opportunities for adversaries. Therefore, a complex defense mechanism should be used to detect and react to malicious activity in 5G networks, similarly to Security Operation Centers (SOC) in computer networks.In this paper, we investigated the open source 5G simulators and their connection possibilities to our existing ELK based SOC and gave a comparison about them. Based on the log messages we managed to send to the SOC, we give an overview of the registration process. According to the status graph of the registration process, we also managed to identify the different states of the registration based on log data generated by the SOC.
