IMS Security Analysis using Multi-attribute Model

IP Multimedia Subsystem (IMS) plays as a core platform in next-generation-network architecture, which advocates for an open and inter-operable service infrastructure. However, over the years, not much attention has been paid to the security problem of IMS. The time has come to now address security issues. This paper proposes a multi-attribute stereo model based on X.805 standard, which addresses a comprehensive, top-down, end-to-end perspective for IMS security analysis, classification and assessment. Besides, a detailed threat analysis of IMS is demonstrated and the vulnerability utilized by the threat is also presented.
