Lab — Hardening
Merge patch governance, hardening checklist, and vendor hygiene sections on YOUR $OT_LAB — defensive OT literacy only; no real-plant attacks, unauthorized OT scans, or exploit cookbooks.
Visual · t38_hardening_lab
Hardening Lab literacy. $OT_LAB only. Original Cyberlium.
Hardening pack merges patch, baseline, and vendor rows — paperwork before incident module.
Lessons 8-1–8-3 named patch governance, hardening baselines, and vendor hygiene. Merge into one OT lab hardening artifact with cross-links to M7 asset inventory. Cyberlium Topic 38 practices on $OT_LAB — YOUR fictional OT templates, zone diagrams, and labeled checklists under $HOME/cyberlium-lab/t38-ot/ no real-plant attacks, unauthorized OT scans, or exploit cookbooks. Next: Quiz — Hardening Practices.
1. What Hardening Lab covers (named)
Create t38-m08-l04-hardening-lab.txt merging M8 sections. Map patch and hardening rows to three fictional assets from M7 inventory. On $OT_LAB, document literacy rows on fictional LAB-OT-001 — never live plant IPs, credentials, or exploit steps.
Include curl reference note for CISA ICS hardening guidance — literacy only. No live system changes. On $OT_LAB, document literacy rows on fictional LAB-OT-001 — never live plant IPs, credentials, or exploit steps.

Primary tools to practice this lesson: grep, curl. Reference sites: CISA ICS (https://www.cisa.gov/resources-tools/resources/ics-recommended-practices); NIST SP 800-82 (https://csrc.nist.gov/publications/detail/sp/800-82/rev-3/final). Run every command in the box — install first, then the usage lines — only on YOUR lab / program scope.
2. Why Hardening Lab matters for defenders
Grep for live firmware binaries, vendor passwords, disable-security steps — redact. Defensive governance only. On $OT_LAB, document literacy rows on fictional LAB-OT-001 — never live plant IPs, credentials, or exploit steps.
Cross-reference M6 remote access and M3 OT/IT patch constraints. Thread continuity. On $OT_LAB, document literacy rows on fictional LAB-OT-001 — never live plant IPs, credentials, or exploit steps.
3. $OT_LAB boundary
chmod 600 — quiz next, then OT IR. Hardening feeds incident response in M9. On $OT_LAB, document literacy rows on fictional LAB-OT-001 — never live plant IPs, credentials, or exploit steps.
Ship: hardening pack. Next: Quiz — Hardening Practices.
4. What you ship: hardening lab card for $OT_LAB
Merge patch governance, hardening checklist, and vendor hygiene sections. $OT_LAB named. NEVER real-plant attack steps. chmod 600.
5. What you record before the next lesson
Date (UTC). Hardening Lab card. $OT_LAB named. File t38-m08-l04-hardening-lab.txt chmod 600.
6. Wrong vs right: plant attacks vs YOUR OT lab sims
Worked failure — same MSF word, opposite target. Right never needs a café Wi-Fi or classmate laptop.
- Wrong: Bundle employer vendor password vault into lab pack.
- Right: Write hardening lab card for YOUR $OT_LAB. Next: Quiz — Hardening Practices.
Mission: document Hardening Lab on YOUR OT lab
1) Name literacy rows on $OT_LAB. 2) Write NEVER list (no real-plant attacks, unauthorized OT scans, or exploit cookbooks). 3) chmod 600. Never scan or exploit real industrial networks.
