Interfaces play a crucial role in the Fifth Generation (5G) architecture as they interconnect Network Functions (NFs) to exchange data and services. Certain interfaces are particularly critical because they are involved in the exchange of sensitive data or are exposed externally. To the best of our knowledge, no literature work analyzes the 5G security from a network architecture or interface perspective. Therefore, existing research on 5G security may not be helpful when considering a certain component of the network or a specific interface. This paper reviews the security measures recommended by the selected Standardization Development Organizations (SDOs) for critical interfaces and classifies them based on security goals. It also identifies vulnerabilities and threats to these interfaces in the absence of security measures and categorizes them based on STRIDE model and impacted traffic types.

关键5G接口的安全分析


接口在第五代 (5G) 架构中发挥着至关重要的作用，因为它们互连网络功能 (NF) 以交换数据和服务。某些接口特别重要，因为它们涉及敏感数据的交换或暴露在外部。据我们所知，还没有文献从网络架构或接口的角度分析 5G 安全性。因此，在考虑网络的某个组件或特定接口时，现有的 5G 安全研究可能没有帮助。本文回顾了选定的标准化开发组织 (SDO) 针对关键接口推荐的安全措施，并根据安全目标对它们进行了分类。它还可以在缺乏安全措施的情况下识别这些接口的漏洞和威胁，并根据 STRIDE 模型和受影响的流量类型对它们进行分类。
