Digital Forensics MSc

• Dr Graeme Horsman

This module provides a general introduction to the awards associated with the MSc Digital Forensics, and the principles underpinning the course. It orients students and provides research skills to prepare students for their subsequent programme of study on the assessed modules. The discussion sessions provide students with an opportunity to network and gain confidence in expressing evidenced professional opinions.

The emphasis in Introductory Studies is on preparing students access and use teaching and University resources. Topics include:

• Course overview and module details,
• Introduction to University facilities and using University Library,
• Student obligations and expectations,
• Coursework submission process and referencing standards,
• Use of the Digital Forensic Labs specific resources.

• Self-evaluate their educational needs and plan remedial action as required,

The aim of this module is to provide students a thorough grounding in the fundamentals of common digital systems, the artefacts associated with such systems and techniques to identify, collect and analyse those artefacts. A mixture of theory and practice will facilitate the development of skills and experience across multiple computing platforms, including networking related artefacts. In addition to preparing students for real-world examination of computers, these skills will serve as a foundation for further study, including the Mobile Device Forensics and Internet-Based Investigations modules.
