About the course
Increasingly, computer networks cannot be considered without the important issue of security; without secure networks, businesses, commerce and communications would all fail. This course addresses the need for modern computer network professionals.
You cover topics such as current and future internet protocols, programming networked services and securing these systems. We offer a strong practical element through laboratory programmes in software engineering and in computer networking; laboratory work in security includes unique environments where the techniques of the attackers can be observed and stopped using specialist security tools.
Our School is a community of scholars leading the way in technological research and development. Today’s computer scientists are creative people who are focused and committed, yet restless and experimental. We are home to many of the world’s top scientists, and our work is driven by creativity and imagination as well as technical excellence.
We are ranked Top 10 in the UK in the 2015 Academic Ranking of World Universities, with more than two-thirds of our research rated ‘world-leading’ or ‘internationally excellent (REF 2014).
This course is also available on a part-time basis.
This degree is accredited by the Institution of Engineering and Technology (IET).This accreditation is increasingly sought by employers, and provides the first stage towards eventual professional registration as a Chartered Engineer (CEng).

This course gives an introduction to computer security and cryptography, and then goes on to consider security as it relates to a single, network connected, computer. Introductory material is independent of any operating system but the consideration of tools will focus on those available for Linux, partly because its open-source nature facilitates this and partly because it is widely used on server systems. The introduction to cryptography will be used to consider its use in encryption and authentication.

This module introduces the Internet and computer networking from both a theoretical and practical perspective. It is the module where computers are merging with communications to create a fundamentally new system - the World Wide Web. The design, organisation, and operation of networks and the Internet are the subject of this module. The areas which are covered in the module are at the heart of modern network-connected world. In brief - the module will provide you as a future computer network specialist with a comprehensive knowledge of design, organisation, and operating principles of modern computer networks. The module first examines the architecture and operation of the Internet protocols (IPs), and shows how information is processed and routed across the Internet. The operation and configuration of routers is discussed alongside the details of protocol operation. The module then discusses the rationale behind the next generation internet protocol IPv6, in particular regarding addressing architecture, header functions, and novel protocol concepts. A comparison between the current IPv4 and the future IPv6 protocols and transition to the next generation protocol are discussed in depth. The function and implementation of its main support protocols are also covered. The application of these new networking ideas is illustrated by the application of IPv6 to problems in network layer services, especially security, and the Internet of Things (IoTs). In order to provide both good theoretical knowledge and strong applied skills, in addition to the lectures the module is supported by the problem solving classes.

The aim of this module is to provide an introduction to computer programming for students with little or no previous experience. The Python language is used in the Linux environment, and students are given a comprehensive introduction to both during the module. The emphasis is on developing the practical skills necessary to write effective programs, with examples taken principally from the realm of data processing and analysis. You will learn how to manipulate and analyse data, graph them and fit models to them. Teaching takes place in workshop-style sessions in a software laboratory, so you can try things out as soon as you learn about them.

We now live in the era of the cloud, fifty years after John McCarthy first proposed that computing could accessed like a public utility, just as we plug a device in to an electricity socket. Cloud computing, making large-scale datacentres and their facilities publically available over the Internet, is now an economic engine of growth. It certainly generates income for the giants of the computing industry, such as Amazon, Google, Microsoft and Oracle. But it also benefits numerous small and medium-sized enterprises (SMEs) that transfer their e-commerce, Big Data, Web and business analytics, and IT applications to a cloud in a way that would have been impossible previously, because the SMEs would have lacked the start-up capital. There are also employment opportunities in third-party companies that manage clouds, help transfer applications to a cloud, and create software to run novel applications on a cloud. The module will therefore be of interest to those hoping to enter the cloud-computing industry. More specifically this module provides students with an understanding of the key architectural features and technologies of cloud computing. It investigates virtualization of resources, the service oriented architecture, large-scale data management, and networking. The module also reviews contemporary developments such as green and mobile cloud computing. A theoretical analysis of cloud technologies is supplemented by analysis of actual data-centres and services, available from major providers including Amazon, Google, and Microsoft. Practical work within the module provides students with hands-on experience of virtualization and the performance of typical applications such as video transcoding and mapReduce-based parallel computation.

We are living in a world of multiple networking technologies, either wired or wireless. There is a need for these network technologies to converge in order to provide seamless services to end users. This course is to look into the fundamentals towards this goal. This course will begin with the motivation behind network and service convergence and then introduce the network architectures that are being deployed today. Then quality of service (QoS) metrics such as delay, jitter, packet loss, etc. and QoS mechanisms will be introduced. The course will go on into various types of service and network convergences covering wireless + wireless convergence and wired + wireless convergence. The course will then describe fundamentals of a key issue that is common for any type of convergence: mobility. Finally the course will finish by introducing a clean-slate future Internet technology called ICN (Information Centric Networking).
