Computer Forensics

Scott R. Ellis, RGL

This guide is intended to provide in-depth information on computer forensics as a career, a job, and a science. It will help you avoid mistakes and find your way through the many aspects of this diverse and rewarding field.

1. What is Computer Forensics?

Definition: Computer forensics is the acquisition, preservation, and analysis of electronically stored information (ESI) in such a way that ensures its admissibility for use as either evidence, exhibits, or demonstratives in a court of law.

Rather than discussing at great length what computer forensics is (the rest of the chapter will take care of that), let’s, for the sake of clarity, define what computer forensics is not. It is not an arcane ability ...
