INFORMATION AND NETWORK SECURITY - 2024/5
Module code: COMM048
The module introduces general information and network security principles, challenges and goals and then focuses on main security mechanisms and protocols for protecting network communication across different layers of the Internet protocol stack. This will include discussion on various attacks on the networks, penetration testing tools and possible countermeasures to ensure protection of authentication, confidentiality and end-to-end security of communications. In labs students will be able to practice experience with various network security protocols and tools.

|Assessment type||Unit of assessment||Weighting|
The assessment strategy is designed to provide students with the opportunity to demonstrate that they have achieved the module learning outcomes.
Thus, the summative assessment for this module consists of:
· An individual coursework with a set of theoretical and practical tasks.
This addresses LO1, LO2 and LO3.
Formative assessment and feedback
Lecture slides are used extensively in the lectures with each lecture consisting of a number of slides explaining the theory and showing the examples. Solutions to lab exercises are explained during the lab session and provided to the students.
- The aim of this module is to equip students with background knowledge and practical experience of modern information and network security mechanisms, including widely used network security protocols and technologies. The module will explain various attacks on the network communications and demonstrate the use of appropriate protection mechanisms. The module will cover theoretical foundations of modern information and network security mechanisms and practical understanding of those mechanisms with their application in the real world.
|1||Understand information and network security principles, challenges and goals that are relevant for the protection of information and network communication against various types of attacks in the real world||KC|
|2||Understand the functionality, advantages and disadvantages of main protection mechanisms and protocols for securing network communications||KCT|
|3||Experience practical application of network security protocols and technologies||KPT|
C - Cognitive/analytical
K - Subject knowledge
T - Transferable skills
P - Professional/Practical skills
Methods of Teaching / Learning
The learning and teaching strategy is designed to:
- Help students understand the nature of information and network security, including main principles, challenges and goals
- Explain threats and attacks arising in the context of network communications
- Explain the functionality of network security protocols and relevant protection mechanisms
- Enable students to apply existing security mechanisms and protocols for the protection of network communications
The learning and teaching methods include:
- Lectures (15 hours) using detailed lecture slides to gauge the students’ understanding
- Labs (10 hours) using computing labs, exercise sheets and their solutions.
Students will be expected to distribute the remaining workload on self-study, preparation for lectures and labs, preparation and submission of the coursework.
Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.

Securing networked systems is currently one of the most in-demand industry areas with applications in many contexts such as finance, IT, science and health. This module provides a grounding in the theory and practice of building secure networked system. Understanding of the underlying principles of network protocols and protection mechanisms are combined with the practical experience of building these systems provides technical skills that are directly applicable in an industry context.
Computer security is a requirement of all network systems and as such the skills taught on this course such as network protocols, and network protection mechanisms are fundamental to the any workplace that develops computer systems. The underlying theory provides the grounding to apply this knowledge to new and unfamiliar scenarios and the practical labs provide technical skills that allow graduates to build fundamental security principles into software from the ground up.
Global and Cultural Skills
Computer Science is a global language and the tools and languages used on this module can be used internationally. Networked systems by definition are distributed systems and this module allows students to develop skills that will allow them to reason about and develop applications with global reach and collaborate with their peers around the world.
Resourcefulness and Resilience
This module teaches both the theory and practical skills to allow students to work with networked systems in a secure manner. It provides the tools to reason about these complex hardware and software systems and to build these systems in a secure manner.
