The Quiet Drift of Evidence

In incident response, the hardest part is rarely finding artifacts — it is keeping context intact while your understanding changes.

Operating principles

• Treat early hypotheses as disposable.
• Preserve raw sources before enrichment.
• Keep a clear separation between collection, interpretation, and narrative.

A small workflow

# Create a case folder
mkdir -p case-{id}/{raw,notes,exports}

# Hash any exported evidence
sha256sum exports/* > exports/SHA256SUMS.txt

Detection engineering tie-in

Good detections are opinionated. Great detections are reversible.

When you write a rule, keep track of what you assumed about environment and attacker tradecraft.
