OT Visibility
OT visibility literacy names passive monitoring, SPAN/TAP placement, and asset discovery boundaries on YOUR $OT_LAB — defensive OT literacy only; no real-plant attacks, unauthorized OT scans, or exploit cookbooks.
Visual · t38_ot_visibility
OT Visibility literacy. $OT_LAB only. Original Cyberlium.
You cannot defend OT blind — literacy names visibility layers without unauthorized active scanning of live plants.
OT visibility combines passive protocol monitoring, asset inventory correlation, and selective safe discovery within approved windows. Cyberlium documents visibility plan rows on fictional LAB-OT-001 — not nmap sweeps of stranger OT subnets. 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: Anomaly Named.
1. What OT Visibility covers (named)
Visibility literacy: passive DPI on conduits, NetFlow at boundaries, historian baseline exports (fictional), safe discovery policy. Active scanning requires OT approval and maintenance windows. On $OT_LAB, document literacy rows on fictional LAB-OT-001 — never live plant IPs, credentials, or exploit steps.
Write visibility plan row — data source, zone, use case, approval requirement. Lab fictional plant only. On $OT_LAB, document literacy rows on fictional LAB-OT-001 — never live plant IPs, credentials, or exploit steps.

2. Why OT Visibility matters for defenders
Passive monitoring reduces process impact vs aggressive scanning. Visibility gaps hide lateral movement. On $OT_LAB, document literacy rows on fictional LAB-OT-001 — never live plant IPs, credentials, or exploit steps.
Students draft visibility rows on lab notes. Production follows OT monitoring architecture standards. On $OT_LAB, document literacy rows on fictional LAB-OT-001 — never live plant IPs, credentials, or exploit steps.
3. $OT_LAB boundary
Forbidden: unauthorized active OT network scans. Allowed: visibility plan literacy on OT lab. On $OT_LAB, document literacy rows on fictional LAB-OT-001 — never live plant IPs, credentials, or exploit steps.

4. What you ship: ot visibility card for $OT_LAB
OT visibility literacy names passive monitoring, SPAN/TAP placement, and asset discovery boundaries. $OT_LAB named. NEVER real-plant attack steps. 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 nmap on plant OT subnet without ticket.
- Right: Write ot visibility card for YOUR $OT_LAB. Next: Anomaly Named.
Mission: document OT Visibility 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.
