Network forensics is the discipline of reconstructing behavior from captured traffic and related network evidence. Good forensics starts with capture quality and disciplined note-taking.
Key questions
- What is the source of the evidence?
- How complete is the capture?
- Can host logs validate what the packet stream suggests?
- Does the timeline align with the observed alert or anomaly?
For me, the most valuable habit is documenting assumptions early so analysis remains transparent and reproducible.
