scope:
This document is part of a suite of signaling and control security standards. Figure 1 illustrates the relationships among these standards. The scope of this document is a Signaling System No.7 (SS7) Network, and SS7 network interconnections. This includes interconnection to other SS7 networks and to multimedia signaling and control networks such as SIP and H.323 networks. Specifically, this document provides security requirements and guidelines for a Signaling System No.7 (SS7) network and its network interconnections.
The traditional SS7 network uses the ISDN User Part (ISUP) call control protocol over a Message Transfer Part (MTP) transport network consisting of dedicated MTP2 or Signaling ATM Adaptation Layer (SAAL) signaling links. This document provides:
♦ Security requirements and guidelines for SS7 networks including the supported application protocols and services.
♦ Security requirements and guidelines regarding interconnection of an SS7 network to other SS7 networks and other signaling network types (e.g., H.323 and SIP).
♦ Security requirements and guidelines related to SS7 network interactions with the management plane (i.e., management networks) and user plane (i.e., bearer networks).
Purpose
The main purpose of this document is to provide guidance and recommendations to network providers and equipment manufacturers in areas of network security. It is also intended to guide industry groups to develop and specify the necessary protocol capabilities or enhancements for security.
