ICS Overview
ICS overview literacy names sensors, controllers, historians, and supervisory layers on YOUR $OT_LAB — defensive OT literacy only; no real-plant attacks, unauthorized OT scans, or exploit cookbooks.

ICS Overview literacy. $OT_LAB only. Original Cyberlium.
You cannot defend what you have not named — map Purdue levels on YOUR fictional plant before claiming OT expertise.
Industrial Control Systems combine field devices, PLCs/RTUs, HMIs, historians, and enterprise interfaces across Purdue Model levels 0–5. Label fictional components in YOUR OT lab — never enumerate live employer OT assets without authorization. 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: SCADA Named.
1. What ICS Overview covers (named)
Level 0 sensors/actuators, Level 1 controllers, Level 2 SCADA/HMI, Level 3 operations, Levels 4–5 enterprise IT. Each level has distinct safety and monitoring priorities. On $OT_LAB, document literacy rows on fictional LAB-OT-001 — never live plant IPs, credentials, or exploit steps.
Write ICS layer card — one fictional component per Purdue level for LAB-OT-001. Not nmap output from plant subnets. On $OT_LAB, document literacy rows on fictional LAB-OT-001 — never live plant IPs, credentials, or exploit steps.
Command guide
Try these commands — What ICS Overview covers (named)
═══ LINUX / macOS (Terminal Practice) ═══
Check system state and user context
Command — copy this
id whoami uname -a
Inspect network sockets listening for connections
Command — copy this
ss -tuln 2>/dev/null || netstat -tuln
Audit active processes
Command — copy this
ps aux | grep -v "\[" | head -15
═══ WINDOWS (POWERSHELL) ═══ Query user identity and system information

Primary tools to practice this lesson: curl, grep. Reference sites: Purdue Model OT (https://www.cisa.gov/topics/industrial-control-systems); 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 ICS Overview matters for defenders
Shared ICS vocabulary aligns IT security and OT engineers. Undocumented assets hide monitoring gaps. On $OT_LAB, document literacy rows on fictional LAB-OT-001 — never live plant IPs, credentials, or exploit steps.
Students draft layer cards on notes. Production models follow CMDB and OT engineering 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: nmap scans of plant OT subnets. Allowed: ICS overview card with fictional components. On $OT_LAB, document literacy rows on fictional LAB-OT-001 — never live plant IPs, credentials, or exploit steps.
Ship: ICS layer card. Next: SCADA Named.
4. What you ship: ics overview card for $OT_LAB
ICS overview literacy names sensors, controllers, historians, and supervisory layers. $OT_LAB named. NEVER real-plant attack steps. chmod 600.
5. What you record before the next lesson
Date (UTC). ICS Overview card. $OT_LAB named. File t38-m02-l01-ics-overview.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: Scan employer OT VLAN to populate ICS inventory.
- Right: Write ics overview card for YOUR $OT_LAB. Next: SCADA Named.
Mission: document ICS Overview 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.
