Title: SYSTEM AND METHOD FOR VOICE SECURITY IN A TELECOMMUNICATIONS NETWORK
Abstract:
Aspects of the present disclosure involve systems, methods, computer program products, and the like, for identifying and mitigating attacks on a voice component of a telecommunications network. In general, the process includes obtaining Layer 3 through Layer 7 transmission information from one or more edge devices to the telecommunications network. In one particular embodiment, a plurality of edge devices (also referred to herein as "session border controllers" or SBCs) is included in the telecommunications network in disparate geographical locations. Each SBC may provide Layer 3 through Layer 7 transmission information for each packet or communication transmitted through the SBC to a local database, which in turn may provide the information to a Central Analysis System or database. In one particular embodiment, the Layer 3 through Layer 7information includes Session Initiation Protocol routing information for the communications sent to each of the SBCs of the network.
