IP Multimedia Subsystem (IMS) as the core of Next Generation Network (NGN), its security is vital
important. However, IMS is a network with openarchitecture based on IP, which brings a lot of
security issues. There has already some research results about IMS security, but systematic and
model-based research results are lacked. Based on TVRA method, this paper establishes a
comprehensive vulnerability analysis model of IMS network, and makes a systematic analysis about
the security objectives, assets, weaknesses, threats and other attributes of IMS network by using
this model. The research results of this paper can provide the basis for the security assessment of
IMS network.
