ICS/SCADA › Module 4 › Lesson 4
Lab — Protocols
Merge Modbus, DNP3/OPC UA, and protocol risk literacy sections on YOUR $OT_LAB — defensive OT literacy only; no real-plant attacks, unauthorized OT scans, or exploit cookbooks.
Visual · t38_protocols_lab
Protocols Lab literacy. $OT_LAB only. Original Cyberlium.
Opening
Protocols pack merges Modbus, DNP3/OPC UA, and risk rows — defensive paperwork before threats module.
Lessons 4-1–4-3 named Modbus, DNP3/OPC UA, and protocol risks with compensating controls. Merge into one OT lab artifact — no exploit steps, curl CISA protocol guidance for literacy only. 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 — Protocols Literacy.
1. What Protocols Lab covers (named)
Create t38-m04-l04-protocols-lab.txt merging three M4 sections. Optional: link risks to M6 zone placeholders. On $OT_LAB, document literacy rows on fictional LAB-OT-001 — never live plant IPs, credentials, or exploit steps.
Include NEVER line: no Modbus exploit cookbooks against real plants. Fictional LAB-OT-001 devices only. On $OT_LAB, document literacy rows on fictional LAB-OT-001 — never live plant IPs, credentials, or exploit steps.

Run every command in the box — install first, then the usage lines — only on YOUR lab / program scope.
2. Why Protocols Lab matters for defenders
Grep pack for exploit payloads, live IP:502 targets, unauthorized fuzz steps — redact. Defensive literacy only. On $OT_LAB, document literacy rows on fictional LAB-OT-001 — never live plant IPs, credentials, or exploit steps.
Cross-reference M1 ethics and M3 OT/IT patch constraints. Keep scope visible. 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 Vectors Named. Protocol literacy feeds named threats in M5. On $OT_LAB, document literacy rows on fictional LAB-OT-001 — never live plant IPs, credentials, or exploit steps.
Ship: protocols literacy pack. Next: Quiz — Protocols Literacy.
4. What you ship: protocols lab card for $OT_LAB
Merge Modbus, DNP3/OPC UA, and protocol risk literacy sections. $OT_LAB named. NEVER real-plant attack steps. chmod 600.
5. What you record before the next lesson
Date (UTC). Protocols Lab card. $OT_LAB named. File t38-m04-l04-protocols-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
Add Modbus write tutorial section to lab pack.
Right
Write protocols lab card for YOUR $OT_LAB. Next: Quiz — Protocols Literacy.
Mission: document Protocols 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.
