scope:

This document addresses generic signaling and control plane security aspects of evolving telecommunications networks. Evolving telecommunications networks often combine legacy telecommunication facilities with new technologies such as Wireless, ATM, and Internet Protocol transport mechanisms. The security recommendations given in this document apply to service provider networks and may also be applicable to individual company corporate enterprise networks.

This document is based on Recommendation X.800, Security Architecture for Open Systems Interconnection for CCITT Applications, and Recommendation X.805, Security Architecture for Systems Providing End-to-End Communications. {Reference [ITU X.800], [ITU X.805]}

This document provides generic signaling and control plane security requirements and a general security framework for evolving telecommunications networks. The concepts presented in this document are intended for use by other related documents which deal with specific signaling and control security areas such as SS7 and VoP/Multimedia security.

The purpose of the family of documents identified in the Foreword is to specify security requirements for signaling and control plane functions of evolving telecommunications networks. These requirements will help assure secure interoperability of equipment from multiple vendors.
