Next Generation Networks

What is an NGN?

NGN stands for Next Generation Network. An NGN is a single network commonly built around Internet Protocol (IP), which is able to provide telecommunications services by sending data in packets. NGNs have evolved because of developments in telecommunications leading to some key architectural changes, with networks moving to new IP-based architectures over the next 5–10 years.

Why is this work needed?

This advance in technology to NGNs has threatened to impact the confidentiality, integrity and availability of the UK telecommunications network. Previously the Public Switched Telephone Network (PSTN) provided a trusted environment for restricted conversations. This is not currently the case for NGNs. Furthermore, there is a gap in the specialist security advice that is available to support NGNs, both for those developing them and those using them.

What is the NGN project about?

The project has two main focuses:

• Research: Developing tools and techniques for the analysis of NGNs.
• Assurance: The design, build and implementation of an industry–wide NGN assurance process that operates at two security levels: minimum and standard. The minimum level is one that all the telecommunications companies will have to meet to be able to provide services in the UK; the standard level is aimed at unclassified government use.

And the benefits?

Consumers will have confidence in the security and resilience of the services they are being offered by the telecommunications companies.

Telecommunications companies will have a well-defined and stated target to aim for in order to demonstrate that good practice is being followed.

This work will build up the level of trust and confidentiality between HMG and the telecommunications companies. The companies will be able to determine the level of service provided by each other, enabling better interoperability agreements between them.
