Module Facts

Run by School of Computer Science and Electronic Engineering

20 Credits or 10 ECTS Credits

Semester 1

Overall aims and purpose

This module aims to:

  • Develop an understanding of the issues surrounding security in computing, networks, within the context of the interconnected modern world.
  • Provide practical experience of defending systems and networks against attacks.
  • Expose students to the comment themes and activities with computer and network security.

Course content

Indicative content includes:

  • Types of actors within the security field.
  • The '3As' of security.
  • Types and methods of attack and defence.
  • Network segmentation and firewalling
  • The Layered Protection Model
  • Encryption, and the guarantees it can provide.
  • Data Protection and Social Engineering.

Assessment Criteria

threshold

Equivalent to 40%. Uses key areas of theory or knowledge to meet the Learning Outcomes of the module. Is able to formulate an appropriate solution to accurately solve tasks and questions. Can identify individual aspects, but lacks an awareness of links between them and the wider contexts. Outputs can be understood, but lack structure and/or coherence.

good

Equivalent to the range 60%-69%. Is able to analyse a task or problem to decide which aspects of theory and knowledge to apply. Solutions are of a workable quality, demonstrating understanding of underlying principles. Major themes can be linked appropriately but may not be able to extend this to individual aspects. Outputs are readily understood, with an appropriate structure but may lack sophistication.

excellent

Equivalent to the range 70%+. Assemble critically evaluated, relevent areas of knowledge and theory to constuct professional-level solutions to tasks and questions presented. Is able to cross-link themes and aspects to draw considered conclusions. Presents outputs in a cohesive, accurate, and efficient manner.

Learning outcomes

  1. Explain the key principles behind encryption and apply them to enhance security.

  2. Apply relevant security theory to design a system for security.

  3. Analyse common vulnerabilities in computers, networks and systems.

  4. Identify common threat vectors and the layered responses to them.
