Description

Learners will examine cyber security in relation to a business environment. In particular, the module will explore specific attacks, attackers motives and threat modelling in a business environment. The learner will critically evaluate the challenges in relation to cyber security and the consequences of a data breach for an organisation. The learner will explore and evaluate different cryptographic systems and how they differ from each other.

Learning Outcomes

On completion of this module the learner will/should be able to;

1.

Evaluate and explore the term Cyber Security and its relevance in a business environment

2.

Analyse security issues, analyse ways businesses can mitigate against security issues and illustrate consequences of security breaches for an organisation

3.

Examine the components of a cryptosystem and analyse different cryptographic attacks

4.

Examine and analyse the principles of Cryptography

Teaching and Learning Strategies

Lectures will be used to present the material throughout the module and laboratory exercises will be used to reinforce the learning experience.

Module Assessment Strategies

Students will be accessed through the application of techniques using case studies/practical elements which will require application of content covered.  Understanding of theoretical concepts will be assessed via an end of module examination.
