| 摘要 |
The present invention relates to a Session Initiation Protocol (SIP) intrusion detection and response architecture for protecting SIP-based services, and more specifically, to an SIP intrusion detection and response architecture for protecting SIP-based services, in which SIP-based attacks of a new type can be coped with by detecting the SIP-based attacks and SIP traffic anomalies and managing an SIP-aware security device without degrading quality of multimedia, and signal and media channels can be examined through an SIP-aware intrusion prevention system (IPS) for the purpose of preventing an attacker from hindering a call through manipulation of an SIP message and session-hijacking among legitimate users and attempting a toll fraud by detouring authentication.
