Digital Forensic Models, Challenges & Ethics

This unit explores the different frameworks used to structure a digital investigation, comparing their phases, strengths, and limitations side by side. Each model is broken down with diagrams to show how evidence moves from identification through to final reporting, along with the advantages and drawbacks investigators should keep in mind when choosing an approach. The notes also examine the real-world obstacles forensic professionals face — from technical hurdles to the growing complexity of modern devices — and how these affect the reliability of an investigation. A dedicated section outlines the ethical responsibilities every investigator is expected to uphold, contrasted with the kinds of conduct that can undermine a case. Useful for understanding both the theoretical structure and the professional standards behind digital forensic work.
