The convergence of the incumbent Signaling System 7 (CSS7) telephony networks with the newer IP signaling networks has been underway for some years. The SS7 networks provide high reliability and availability access to landline and mobile phones in support of billing, short message, number translation, calling card verification, and other services. These signaling networks inherit the security threats from the IP networks: Denial of service attacks, malware, eavesdropping, man-in-the-middle attacks, and others. This presentation explores some of those security threats and examines a mathematical approach for detecting the presence of intrusions. The IP Multimedia Subsystem (IMS) architectural framework is used as the reference model for delivering multimedia services. An Element Management System (EMS) is used as the reference platform where network data is consolidated. A Security Management adjunct system is proposed which pulls data from the EMS and applies mathematical algorithms to the data to detect intrusions.
