Digital Forensics

Evidence acquisition, chain of custody, and incident reconstruction — optional deep dive.

Prerequisite: Defense & Detection

What you'll actually learn

Digital forensics isn't about finding evidence — it's about finding evidence in a way that still holds up after someone else tries to tear it apart. This track covers how to acquire evidence without altering it, why chain of custody is a legal requirement and not paperwork theater, and how to reconstruct the actual sequence of an incident from artifacts (timestamps, deleted files, memory dumps) that most people would overlook or accidentally destroy just by looking at them wrong.

What you'll be able to do

You'll take a compromised system's disk image and memory dump and reconstruct what actually happened — not a guess, a defensible timeline built from artifacts, handled the way a real investigation requires so the evidence remains admissible. That's the real difference between "I think this is what happened" and being able to prove it.
