Approaches to Teaching and Learning:
This module will be taught primarily through lectures covering a range of introductory topics in cybersecurity. Learning will be supported through the use of practical examples and case-based discussion, enabling students to relate key concepts to on-going cybersecurity challenges. Students will be expected to engage in independent study to consolidate and extend their understanding of the material introduced in class. Critical writing will be developed and assessed through the module assignment. Guidance will be provided on the appropriate, ethical, and policy-compliant use of AI tools in the module, consistent with University academic integrity requirements.
