OT IT Diff
OT vs IT literacy names conflicting priorities — safety, availability, patch cadence, and ownership on YOUR $OT_LAB — defensive OT literacy only; no real-plant attacks, unauthorized OT scans, or exploit cookbooks.

OT IT Diff literacy. $OT_LAB only. Original Cyberlium.
Opening
IT wants rapid patches; OT wants stable processes — literacy names the tension so defenders collaborate instead of breaking production.
OT prioritizes safety and continuous operation; IT prioritizes confidentiality and rapid vulnerability response. Cyberlium documents priority comparison rows on fictional LAB-OT-001 — not blanket IT policies applied without OT approval. 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: Safety First.
1. What OT IT Diff covers (named)
OT: safety interlocks, 24/7 availability, weeks-long patch windows, vendor dependencies. IT: MFA everywhere, monthly patching, endpoint EDR, rapid credential rotation. On $OT_LAB, document literacy rows on fictional LAB-OT-001 — never live plant IPs, credentials, or exploit steps.
Write OT vs IT priority row — patch cadence, downtime tolerance, ownership. On fictional plant template only. On $OT_LAB, document literacy rows on fictional LAB-OT-001 — never live plant IPs, credentials, or exploit steps.

OT vs IT — NAMED LITERACY:
OT priority: safety, availability, process continuity
IT priority: confidentiality, rapid patching, endpoint controls
OT patch: maintenance windows + vendor validation
Governance: joint OT/IT change control — fictional LAB-OT-001

2. Why OT IT Diff matters for defenders
Blind IT scanning or patching can trip PLCs. Joint governance and IEC 62443 zones reduce conflict. On $OT_LAB, document literacy rows on fictional LAB-OT-001 — never live plant IPs, credentials, or exploit steps.
Students draft comparison cards on notes. Production follows OT/IT governance committees. On $OT_LAB, document literacy rows on fictional LAB-OT-001 — never live plant IPs, credentials, or exploit steps.
3. $OT_LAB boundary
Forbidden: pushing IT patch policy to live PLCs without MOC. Allowed: OT/IT comparison literacy card. On $OT_LAB, document literacy rows on fictional LAB-OT-001 — never live plant IPs, credentials, or exploit steps.
Ship: OT vs IT priority card. Next: Safety First.
4. What you ship: ot it diff card for $OT_LAB
OT vs IT literacy names conflicting priorities — safety, availability, patch cadence, and ownership. $OT_LAB named. NEVER real-plant attack steps. chmod 600.
5. What you record before the next lesson
Date (UTC). OT IT Diff card. $OT_LAB named. File t38-m03-l01-ot-it-diff.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
Run IT vulnerability scan on OT VLAN without approval.
Right
Write ot it diff card for YOUR $OT_LAB. Next: Safety First.
Mission: document OT IT Diff 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.
