scope:

This Standard provides guidelines and requirements for security aspects of ETS communications relevant to the user plane. The user plane consists of those aspects related to the user and includes what is called the bearer plane. Security of the other planes in the telecommunications network model (i.e., the signaling and control plane, and the management plane) is not within the scope of this Standard. Non-traceability and the impacts on performance of security for ETS are also outside the scope of this document and may be addressed in future documents.

Purpose

The purpose of this Standard is to provide security guidelines and requirements relating to ETS communications. What is needed is a consistent set of recommended security guidelines and requirements for the ETS as they relate to user plane performance, reliability, and availability of IPbased networks. The guidelines and requirements provided are specific to ETS, but may be applicable to other communications services provided over IP networks. In addition, security guidelines for the signaling and control plane and the management plane are also needed, but are not addressed in this document.
