Security Threats and Solutions for Application Server of IP Multimedia Subsystem (IMS-AS)

چکیده
In this paper we will explore security threats and attacks possibility and security solution for Application Server of IP Multimedia Subsystem(IMS-AS). The SIP Application Server is an important entity of IP Multimedia Subsystem (IMS) because applications providing value added services are deployed on the Application Server. The SIP Application Server is triggered by Serving Call State Control Function (S-CSCF) which will redirect certain messages to IMS-AS based on internal filters and criteria or by requesting filter information from Home Subscriber Server (HSS). The critical security attacks on IMS-AS include flooding attacks, messages flows attacks etc. We will propose two tiers security mechanism based on Security Architecture for the TLS (Transport Layer Security) and Intrusion Detection System (IDS) against these attacks to secure IMS Application Server. This work is part of Secure Service Provisioning (SSP) Framework for IP Multimedia Subsystem (IMS) 3G beyond Testbed of Fokus Fraunhofer.

IMS (IP Multimedia Subsystem) network is considered as an NGN (Next Generation Network) core networks by ETSI. Decomposition of IMS core network has resulted in a rapid increase of control and signaling message that makes security a required capability for IMS commercialization. The control messages are transmitted using SIP (Session Initiation Protocol) which is an application layer protocol. ...

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 vulnera...
