Visual · t26_lab_path

Lab path = visual case chain on YOUR $DFIR_LAB. Original Cyberlium.

Opening

Draw the path from authority check to mentor handoff — with stop signs at every unauthorized shortcut.

Document literacy path: $DFIR_LAB dataset → intake/authority → preserve/hash → acquire → disk/memory/net analysis → timeline/correlation → report/exhibits → case handoff. Ethics gates: unauthorized device, tampering, forged logs, scope creep, hash skip, confirmation bias — refused paths labeled red. UTC milestones and artifact IDs per station. Mermaid or sketch chmod 600. Honest N/A if brief skipped memory — labeled. Defender breakpoint: where hash verification or limitations paragraph shortened wrong path to finding.

1. Path stations

Intake, preserve, acquire, analyze branches, timeline, report, handoff — eight minimum.

Each station links evidence index row and module lesson ID.

Command — copy this

export LAB_DFIR=${LAB_DFIR:-$HOME/cyberlium-lab/t26-dfir}
sha256sum "$LAB_DFIR/evidence/"* "$LAB_DFIR/pcap/"*.pcap 2>/dev/null | tee "$LAB_DFIR/report/capstone-all-hashes.txt"
strings "$LAB_DFIR/evidence/sample.bin" | tee "$LAB_DFIR/report/capstone-strings.txt"
grep -E 'sample|pcap|CYBERLIUM' "$LAB_DFIR/report/capstone-all-hashes.txt" "$LAB_DFIR/report/capstone-strings.txt" 2>/dev/null | head -8

Primary tools to practice this lesson: sha256sum, strings. Reference sites: Integrity capstone (https://www.nist.gov/itl/ssd/software-quality-group/computer-forensics-reference-data-sets-cfreds); Sleuth Kit (https://www.sleuthkit.org/); SANS DFIR (https://www.sans.org/cyber-security-skills/digital-forensics/). Run every command in the box — install first, then the usage lines — only on YOUR lab / program scope.

2. Ethics overlay

Red stops: unauthorized access, plant/tamper, forged logs, leaked dumps, scope creep.

Authority branch always green start — no shortcut.

3. Integrity breakpoint

Mark where hash verification or ethics checklist prevented bad analysis.

One paragraph uplift from YOUR $DFIR_LAB path.

4. What you ship: lab path diagram

Case chain with ethics gates + UTC milestones — chmod 600.

5. What you record before the next lesson

Lab path diagram path.

6. Wrong vs right: tampering evidence vs chain of custody

Worked failure — same MSF word, opposite target. Right never needs a café Wi-Fi or classmate laptop.

  • Wrong

    Lab path includes unauthorized acquisition shortcut lane.

  • Right

    Lab path documented for $DFIR_LAB. Next: Evidence Pack.

Mission: lab path diagram

1) Map eight stations. 2) Add six ethics gates. 3) UTC milestones per station. 4) Link evidence index IDs.
