Module will run

Occurrence	Teaching period
A	Spring Term 2022-23

Module aims

This module provides an introduction to computer forensic analysis, sufficient to enable a student to understand the disciplines and processes required to obtain and preserve evidence, and the practical skills necessary to conduct and report a basic forensic examination. The module is set in the context of security incident response, and includes both the examination of computers which may have been the origin or victim of unwanted user action, and also the preliminary investigation and classification of malware.

Module learning outcomes

At the end of the module the student will understand:

• the requirements that must be met to allow evidence to be presented in court, and standard approaches to the forensic processes to support such requirements.
• how to produce reports which communicate complex technical analyses to a non-expert audience
• how low-level elements of a computer system (CPU, memory management, processes, file systems) give rise to persistent evidence of how a system has been used.
• how to to prepare for, and conduct analysis of digital systems in order to produce evidence for a range of purposes
• data structures used by browsers, and evaluate evidence of Internet browsing obtained from this source.
• how to make reasoned judgments about the protection and functionality required of systems used to investigate potential malware
