Why OT Sec
OT security literacy means safety-aware defensive vocabulary on YOUR $OT_LAB — defensive OT literacy only; no real-plant attacks, unauthorized OT scans, or exploit cookbooks.

Why OT Sec literacy. $OT_LAB only. Original Cyberlium.
Opening
OT failures can injure people — Cyberlium teaches defender vocabulary on YOUR fictional plant, not attack recipes against live infrastructure.
OT security protects processes where downtime or manipulation affects safety and critical services. Analysts need Purdue model literacy, zone thinking, and CISA-aligned defensive habits — not Modbus exploit scripts against real PLCs. 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: Lab Sims Only.
1. What Why OT Sec covers (named)
OT security spans asset inventory, segmentation, monitoring, patch governance, vendor access, and incident reporting. Named frameworks include IEC 62443 zones and NIST SP 800-82 OT guidance. On $OT_LAB, document literacy rows on fictional LAB-OT-001 — never live plant IPs, credentials, or exploit steps.
Literacy means naming these activities in job descriptions and advisories. It does not authorize scanning stranger substations or manipulating live controllers. On $OT_LAB, document literacy rows on fictional LAB-OT-001 — never live plant IPs, credentials, or exploit steps.

Reference sites: CISA ICS (https://www.cisa.gov/topics/industrial-control-systems); NIST SP 800-82 (https://csrc.nist.gov/publications/detail/sp/800-82/rev-3/final); IEC 62443 (https://www.isa.org/standards-and-publications/isa-standards/isa-iec-62443-series-of-standards). Run every command in the box — install first, then the usage lines — only on YOUR lab / program scope.
2. Why Why OT Sec matters for defenders
Safety and availability dominate OT tradeoffs. Untested changes can trip interlocks or blind operators during incidents. On $OT_LAB, document literacy rows on fictional LAB-OT-001 — never live plant IPs, credentials, or exploit steps.
Students practice scope cards on notes. Production OT follows change control and qualified OT engineers. On $OT_LAB, document literacy rows on fictional LAB-OT-001 — never live plant IPs, credentials, or exploit steps.
3. $OT_LAB boundary
Forbidden: real-plant attacks and unauthorized OT discovery. Allowed: topic scope sentence naming OT lab fictional LAB-OT-001 only. On $OT_LAB, document literacy rows on fictional LAB-OT-001 — never live plant IPs, credentials, or exploit steps.

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
Treat Topic 38 as license to fuzz Modbus on a live water plant.
Right
Write why ot sec card for YOUR $OT_LAB. Next: Lab Sims Only.
Mission: document Why OT Sec 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.
