The IMS is an overlay network on top of IP that uses SIP as the primary signaling mechanism. As an emerging technology, the SIP standard will certainly be the target of Denial of Service (DoS) attacks and consequently IMS will also inherit this problem. The objective of proposed architecture for IMS is to cram the potential attacks and security threats to IP Multimedia Subsystem (IMS) and explore the security solutions developed by 3GPP.

  • (Ims) Architecture
    InSight: RIVIER ACADEMIC JOURNAL, VOLUME 4, NUMBER 1, SPRING 2008 AN OVERVIEW OF INTERNET PROTOCOL MULTIMEDIA SUBSYSTEMS (IMS) ARCHITECTURE Jhansi Jujjuru* Graduate Student, M.S. in Computer Science Program, Rivier College Keywords: IMS Architecture, Application Servers in IMS, IMS Protocols Abstract Internet Protocol Multimedia Subsystems (IMS) is an internationally standardized Next Generation Networking (NGN) architecture for telecom operators in order to provide mobile and fixed multimedia services. It uses Voice-over-IP (VoIP) implementation based on a 3GPP-standardised implementation of Session Initiation Protocol (SIP), and runs over the standard Internet Protocol (IP). It also specifies interoperability and roaming, and provides bearer control, charging and security. IMS is well integrated with existing voice and data networks, while adopting many of the key characteristics of the IT domain. This makes IMS a key enabler for fixed-mobile Convergence and value-based charging. IMS also supports existing Packet-Switched and Circuit–Switched phone systems. 1. Introduction Recently, web based multimedia services have gained popularity and have proven themselves to be viable of communication. This has inspired the telecommunication service providers and network operators to reinvent themselves to try and provide value added IP centric services. There was a need for a system, which would allow new services to be introduced rapidly with reduced capital expense (CAPEX) and operational expense (OPEX) through increased efficiency in network

  • Implementing Security in an IP Multimedia Subsystem (IMS) Next Generation Network – a Case Study
    IMPLEMENTING SECURITY IN AN IP MULTIMEDIA SUBSYSTEM (IMS) NEXT GENERATION NETWORK – A CASE STUDY By Jose M. Ortiz-Villajos A Thesis Submitted to the Faculty of The College of Engineering and Computer Science in Partial Fulfillment of the Requirements for the Degree of Master of Science Florida Atlantic University Boca Raton, Florida April 2009 ABSTRACT Author: Jose M. Ortiz-Villajos Title: Implementing Security in an IP Multimedia Subsystem (IMS) Next Generation Network – A Case Study Institution: Florida Atlantic University Dissertation Advisor: Dr. Eduardo Fernandez Degree: Master of Science Year: 2009 The IP Multimedia Subsystem (IMS) has gone from just a step in the evolution of the GSM cellular architecture control core, to being the de-facto framework for Next Generation Network (NGN) implementations and deployments by operators world-wide, not only cellular mobile communications operators, but also fixed line, cable television, and alternative operators. With this transition from standards documents to the real world, engineers in these new multimedia communications companies need to face the task of making these new networks secure against threats and real attacks that were not a part of the previous generation of networks. We present the IMS and other competing frameworks, we analyze the security issues, we present the topic of Security Patterns, we introduce several new patterns, including the basis for a Generic Network pattern, and we apply these concepts to designing a security architecture for a fictitious 3G operator using
