Building a home OT/ICS (Operational Technology/Industrial Control Systems) cyber security lab doesn’t have to be expensive. Below are free and low-cost alternatives to help you get started.
1. Free Realistic Virtual Lab – Labshock
Labshock is a new virtual platform for OT/ICS testing, ideal for learning defense and penetration testing in industrial environments.

2. Free Realistic Virtual Lab – GRFICS
GRFICS (Graphical Realism Framework for Industrial Control Simulation) provides virtualized ICS environments, including power plants with CCTV simulation.
🔗 GRFICS
3. ICS/OT Honeypots
- Conpot – A low-interaction ICS honeypot.
- T-Pot (ICS/OT versions) – A multi-honeypot platform for threat intelligence.
4. Learning Platforms
- TryHackMe – Limited ICS/OT labs (some require a subscription).
- Hack The Box (Alchemy Platform) – Dedicated OT network for brewery simulations (developed with Dragos).
You Should Know:
Setting Up a Basic ICS/OT Lab
1. Virtualization with Docker & Kali Linux
<h1>Install Docker (Linux)</h1> sudo apt update && sudo apt install docker.io sudo systemctl enable --now docker <h1>Run Conpot ICS Honeypot</h1> docker run -d -p 80:80 -p 102:102 -p 502:502 -p 161:161/udp honeytrap/conpot
2. Simulating PLCs with OpenPLC
<h1>Install OpenPLC on Linux</h1> git clone https://github.com/thiagoralves/OpenPLC_v3.git cd OpenPLC_v3 ./install.sh
3. Network Monitoring with Wireshark & Tshark
<h1>Capture Modbus traffic</h1> tshark -i eth0 -Y "modbus" -w modbus_traffic.pcap
4. ICS/OT Penetration Testing Tools
- PLCScan – Detect PLCs in a network.
- Modbuspal – Simulate Modbus devices.
- Metasploit (SCADA modules) – Test vulnerabilities in ICS systems.
Hardware Options (If Budget Allows)
- Automation Direct – Affordable PLCs, HMIs, and sensors (~$400 for a full setup).
- SANS ICS/OT Trainer Kits – Pre-built lab environments.
What Undercode Say:
Building an OT/ICS lab is essential for hands-on cybersecurity training. Start with free virtual labs like Labshock and GRFICS before investing in hardware. Use Docker for quick honeypot deployments, OpenPLC for simulating industrial controllers, and Wireshark for traffic analysis. For penetration testing, leverage Kali Linux tools and Metasploit’s SCADA modules.
Expected Output:
A functional OT/ICS lab setup with virtual environments, simulated PLCs, and network monitoring capabilities.
