Networks, Communication, and Cyber Defence

Learn to:
  • Explain the key principles behind the organisation and operation of typical communication networks and layered protocols
  • Configure network devices to achieve required operating characteristics
  • Explain network behaviour from captured network traffic

Why is this important?

The internet and computer networks are now ubiquitous, and a growing number of computing activities strongly depend on the correct operation of the underlying network. Networks, both fixed and mobile, are a key part of the computing environment, and many computing applications that are used today would not be possible without networks. This dependency on the underlying network is likely to increase in the future.

This module will develop your understanding of core networks and communications concepts, including their application in the dominant suite of protocols comprising Ethernet, Internet Protocol (IP), Transmission Control Protocol (TCP) and User Datagram Protocol (UDP), the practical realisation of devices to operate these protocols (switches, routers and firewalls in particular), and the cyber consequences of the organisation and configuration of these devices.


Module content will cover:

  • networked applications
  • reliable data delivery
  • routing and forwarding
  • local area networks
  • resource allocation
  • mobility

Delivery and assessment

14 half-day sessions will be regularly spaced across Year 1. Within each half day session, there will be a mix of lecture, tutorial and practical activity.

Assessment is 70% coursework and 30% examination for this module.
