5GCN中的多阶段威胁建模与安全监控

Multi-Stage Threat Modelling and Security Monitoring in 5GCN

Robert Pell, Sotiris Moschoyiannis, Emmanouil Panaousis

摘要:

第五代移动网络(5G)承诺了一系列新功能,包括更高的数据率和更多的连接用户。为了支持新的功能和用例,5G核心网络(5GCN)将是动态和可重新配置的,以满足需求。正是这些改进也为传统的安全监控方法和技术引入了问题,这些方法和技术需要适应新的网络架构。不断增加的数据量和动态的网络架构意味着需要一种方法来将安全监控资源集中在最需要的地方,并对网络变化做出实时的反应。在考虑多阶段威胁场景时,需要一种协调的集中式安全监控方法,以早期检测可能影响网络不同部分的攻击。在本章中,我们确定了克服这些挑战的潜在解决方案,首先确定5G网络的威胁,以确定5GCN中合适的安全监控位置。

英文摘要:

The fifth generation of mobile networks (5G) promises a range of new capabilities including higher data rates and more connected users. To support the new capabilities and use cases the 5G Core Network (5GCN) will be dynamic and reconfigurable in nature to deal with demand. It is these improvements which also introduce issues for traditional security monitoring methods and techniques which need to adapt to the new network architecture. The increased data volumes and dynamic network architecture mean an approach is required to focus security monitoring resources where it is most needed and react to network changes in real time. When considering multi-stage threat scenarios a coordinated, centralised approach to security monitoring is required for the early detection of attacks which may affect different parts of the network. In this chapter we identify potential solutions for overcoming these challenges which begins by identifying the threats to the 5G networks to determine suitable security monitoring placement in the 5GCN.
