Module details for Introduction to Security

Description

This module introduces students to the broad area of computer security within the context of current legal frameworks.

Aims

The aim of this module is to provide the student with knowledge of the issues and practicalities involved in securing computer systems and the framework within which computer security specialists (for example an ethical hacker or digital forensic investigator) would need to operate.

Learning Outcomes

By the end of this module the student should be able to:

1.  Describe the fundamental laws that relate to computer security

2.  Describe some techniques that can be used to improve or evade computer security defences

3.  Conduct an investigation into an area of computer security within a legal framework
