基于IMS网络安全与防御的研究

Study of IP Multimedia Subsystem Security Threat and Defence

当前,电信网络在逐渐向全IP的能提供多种业务能力的融合的下一代网络发展演进,而IMS网络将成为全业务下一代网络的核心。本文系统阐述了IMS网络的安全策略,对其安全需求、架构及组件的实施提出了指导意见。并对于关键性威胁防御点进行了具体分析,为运营商制定网络演进策略提供参考。

This paper describes the overall strategy used to guide the architecture, requirements, and implementation of the security capabilities in the various elements that comprise the IP Multimedia Subsystem （IMS） solution. Security architecture also be introduced, especially the mechanisms that will be used to mitigate the key threats, which can be referenced by the telecom carriers.
