In this paper we presented the security vulnerabilities, threats, and possible attacks for IP Multimedia Subsystem and the appropriate Security Gateway and IPSec Tunneling. Multimedia Subsystemis an architectural framework for delivering Protocol services is in need of more secure connection between interconnected networks. IMS unifies applications that are based on SIP (Session Initiation Protocol), a next-generation packet-based signaling protocol that enables rich multimedia sessions (voice, images, and video).The proposed solution is based on the definition of a Security Gateway for the internetworking between IMS and the Internet. The main functions to be performed by the SEG are discussed, and then the security procedures are briefly presented.
