CT6034 Advanced Networking and Security

Advanced Networking & Security

CT6034

1. Introduction

1.1 Overview

The aim of this module is to build on the network design and implementation principles from module CT5047. The objective is to defend and protect the network infrastructure, architecture, protocols and applications in order to deliver secured protocols, applications, services and data. The cyber security framework of identifying, protecting, detecting, responding and recovery in relation to network security will be evaluated and critically analysed during the module.

Students will be capable of analysing, designing and managing the requirements of a secure network architecture based on risk analysis and operational requirements in accordance with regulations and standards.

1.2 Prerequisites

Basic understanding of networking is crucial for this module. Students are advised to make sure they review the content of CT5047 before starting this module in case they are not confident with their knowledge in networking.

1.3 Reading List

The resources needed for this module are available via the University’s Digital Library, and are as follows:

  • Randy Weaver (2013). Guide to Network Defense and Countermeasures 3rd edition. Boston: Thomson Course Technology.
  • Chris Sanders (2011). Practical Packet Analysis. 2nd edition. San Francisco: No Starch Press.
  • Roberto Verdone (2008), Wireless sensor and actuator networks : technologies, analysis and design
  • Matthijs Kooijman (2015), Building wireless sensor networks using Arduino : leverage the powerful Arduino and XBee platforms to monitor and control your surroundings

2. Learning Outcomes

A student passing this module should be able to:

  1. Critically analyse and evaluate risk analysis and management strategies to address the associated risks, threats, vulnerabilities and attack vectors against network architectures to secure the operational and service delivery requirements;
  2. Critically evaluate the organisational security requirements for a network security solution against known regulations, standards, legislation, policies and procedures to develop a systematic solution to the network and organisational security requirements;
  3. Demonstrate the ability to understand and synthesize the principles of network security architectures and security frameworks and models;
  4. Critically analyse and evaluate network security controls and mitigation techniques: network monitoring, firewalls and traffic filtering, intrusion detection and prevention systems, intrusion analysis, anti-malware, cryptography, securing network protocols, services, applications and data to mitigate the identified risks of the evaluated system;
  5. Analyse a number of advanced networking topics and future networking direction;
  6. Critically evaluate and communicate network security alternatives arguments, assumptions, abstract concepts and data to make judgments, and to frame appropriate questions to achieve a solution - or identify a range of solutions - to a given problem, to both technical and nontechnical stakeholders.

3. Module Evaluation

3.1 Evaluation for 2019-20

We have received quite interesting reviews about this module. Students loved the idea of being exposed to advanced networking topics, including SDN, IDS and WSN. They used a wide range of simulations and tools to do the assignment. Some of the students decided to do their dissertation based on the tools they learnt and used in this module, which shows how much they found the module interesting and practical. Some of the students requested for developing dedicated labs with actual hardware for this module, which we are currently considering it.

In this current academic year 2020/21, you will be given the opportunity to undertake a mid-module evaluation. This will contribute to the course board of studies meeting and will inform the module design for the following year. In addition, there will be an independent end of year level evaluation distributed by the University known as the Annual Course Evaluation (ACE).
