Abstract: With the widespread deployment of 5G networks, establishing effective network security assessment mechanisms has become increasingly important to ensure network safety and mitigate risks. This paper proposes a standardized 5G network security assessment process to address the security risks arising from the complexity of 5G technology, the iterative nature of standards, and the diversity of applications. The approach includes an integrated suite of technical solutions such as a digital twinbased 5G security parallel simulation testing platform, security penetration techniques based on the ATT&CK model, and 5G security fuzz testing. These solutions have been incorporated into a practical 5G security evaluation framework and validated through realworld case studies. The results demonstrate that the proposed assessment process and technologies effectively address emerging security challenges and enhance the overall security of 5G networks.
