Vulnerability Analysis of Service Architecture in NGN

Network scale, applied technologies and supported services of next generation network have exceeded the capability of traditional telecommunication network. At the same time, the security risks in NGN are more than any kinds of current networks. The paper analyzes the vulnerabilities existing in the network structure, service access control, usability of service resources and security mechanism of service architecture according to the features of NGN. The vulnerability analysis results from multiple views clears the security risks and provides a studying basic to solve the security problems in NGN.
