Module Overview

Security is probably the greatest challenge for computer and information system in the near future. Many users have lost data due to viruses, both on home and business computers. Most of us have seen a range of emails massages attempting different kinds of fraud. Vulnerabilities are everywhere. Some are obvious or well-known; others are obscure and harder to spot. Security is not limited to secrecy and confidentiality, but also involves problems like integrity, availability, and effectiveness of information. Moreover, security issues can potentially affect all of us, from innocent home users to companies and even governments.

Security is not just a technical problem but needs to be embedded throughout an organisation to be effective. As such good security solutions build on a complete understanding of the values at stake, and the supporting business processes and requirements. This includes people as well as information systems and physical resources. Consequently, raising security awareness and embedding security within roles and policies is as important, if not more, as secure software. In short, secure solutions can only be implemented with both good technical skills and a good understanding of cultures and people skills.

This module aims at raising the awareness for the wide range of security issues present in today’s connected world and the technical and organisational challenges a business must face when building a secure solution.

Assessment Strategy

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:

· Two individual reports on security incident analysis and security risk assement. These will address LO1, 2, 4 and 5.

· An exam testing all LOs.

The individual courseworks will be due towards the middle and end of the 11 weeks teaching block. The exam takes place at the end of the semester during the exam period.


Formative assessment and feedback

No formative assessment is provided but feedback is given during the class discussions, lab sessions and workshops and as part of the feedback provided for the summative assessments, e.g., lectures will conclude with an activity sheet and feedback will be provided on answers provided.


Module aims

  • The aim of the module is to equip the students with the analytical skills and knowledge to assess security in large systems and organisations, and to incorporate appropriate levels of security in the various steps of a systems lifecycle.

Overall student workload

Independent Study Hours: 117

Lecture Hours: 38

Methods of Teaching / Learning

The learning and teaching strategy is designed to help students achieve the learning outcomes of the module through

in-class discussions of case studies and news articles
in-class group exercises
individual assignment
practical lab sessions

The learning and teaching methods include:

Lectures (11 weeks at 1h)
Tutorial, workshop or lab sessions (11 weeks at 2h)


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.
