Requisites for this module



Key module for

BSC YHG1 Digital and Technology Solutions (Software Engineer)

Module description

This course considers security as it relates to a single computer at an introductory level. Cryptography is introduced and the various scenarios that involve encryption and authentication are investigated. There will be practical work that will give students an opportunity to explore key security tools. The management and planning issues are covered in policy and risk management.

Learning Outcomes

After completing this module, students will be expected to be able to:

1. Identify and describe common security vulnerabilities.
2. Describe the nature of malicious code and how it can spread, be identified and removed.
3. Compare the performance of various cryptographic schemes.
4. Explain the principles of risk analysis and use risk analysis to select controls.

Outline Syllabus
