TAILIEUCHUNG - Exploring IMS Network Security for Next Generation Network (NGN) Carriers

From the early days of the Internet, when only e-mail servers were on the network, a hacker’s ultimate goal was to gain root access to the UNIX host that ran these applications. With root access, the hacker had full control of the system and could often collect enough information to gain access to the rest of the network and other partner networks. E-business application hosts have increased the number of targets for hackers. Hackers often exploit security vulnerabilities, or security holes, in the operating systems or applications of these hosts that system administrators have not safeguarded. Using buffer overflows, trojan horses, and other common techniques,. | Exploring IMS Network Security for White Next Generation Network NGN Carriers Paper High Performance Multi-threat Security Solutions EIERKiniHl- The New Telecom Revolution The telecom industry has entered a phase of revolutionary change as Internet technologies are enabling a new era of multimedia services that are dramatically changing business models. New multimedia services are driving explosive new revenue growth while the use of open systems Internet-based technologies are dramatically reducing capital and operating costs. These are exciting opportunities yet they also present daunting challenges for telecom carriers. Time-to-market competitive differentiation customer satisfaction and cost control become increasingly critical to subscriber retention control of the value revenue chain and ultimately business success. The Technology Evolution Internet or Internet Protocol IP technology is the catalyst of change driving the telecom revolution in the following fundamentally important areas - Network Infrastructure - Open System Platforms - Broadband Multimedia Applications Services Carrier network infrastructure is undergoing a dramatic yet evolutionary change from a circuit-switched to a packet-switched architecture utilizing IP technology for service delivery. The increased efficiencies of IP technology enable networks delivering much greater capacity and higher performance which thereby reduces capital costs. The network infrastructure evolution to IP technology has in turn driven the deployment of open system platforms. Carriers are able to leverage much greater economies of scale and negotiating power to reduce capital equipment costs versus vendor proprietary systems while accelerating time-to-market for new services development deployment through the use of industry standard tools. Now possible are broadband multimedia applications services that allow carriers to offer new high-value services. Multimedia messaging video games music and many new multimedia
