O-RAN 建立了先进的无线接入网络 (RAN) 架构，支持可互操作、多供应商和人工智能 (AI) 控制的无线接入网络。 O-RAN 独特的组件、接口和技术使其有别于 3GPP RAN。由于O-RAN支持3GPP协议，目前支持4G和5G，同时提供额外的网络接口和控制器，因此它具有更大的攻击面。必须仔细评估 O-RAN 的安全要求、漏洞、威胁和对策，使其成为 5G Advanced 和未来 6G 无线的平台。本文介绍了 O-RAN 联盟正在进行的标准化活动，用于对网络尤其是开放前传接口的潜在威胁进行建模。我们识别端到端安全威胁，并更详细地讨论开放前传中的威胁。然后，我们提供应对已识别安全风险的对策建议，并鼓励行业制定标准和最佳实践，以安全可靠地实施开放式前传接口。
O-RAN establishes an advanced radio access network (RAN) architecture that supports inter-operable, multi-vendor, and artificial intelligence (AI) controlled wireless access networks. The unique components, interfaces, and technologies of O-RAN differentiate it from the 3GPP RAN. Because O-RAN supports 3GPP protocols, currently 4G and 5G, while offering additional network interfaces and controllers, it has a larger attack surface. The O-RAN security requirements, vulnerabilities, threats, and countermeasures must be carefully assessed for it to become a platform for 5G Advanced and future 6G wireless. This article presents the ongoing standardization activities of the O-RAN Alliance for modeling the potential threats to the network and to the open fronthaul interface, in particular. We identify end-to-end security threats and discuss those on the open fronthaul in more detail. We then provide recommendations for countermeasures to tackle the identified security risks and encourage industry to establish standards and best practices for safe and secure implementations of the open fronthaul interface.
