OT CYBER DEFENCE
OT Cyber Defence is created to make operational technology cybersecurity easier to understand and apply. The site focuses on practical OT and ICS security, maritime cybersecurity, building hands-on OT labs, OT penetration testing, industrial networking, and real-world security lessons.
Learn how to build a low-cost OT cybersecurity lab at home using a Raspberry Pi Zero 2 W and OpenPLC. Create a working OT environment with physical I/O, OpenPLC, ScadaBR and Modbus TCP, capture industrial network traffic using Wireshark, and test Modbus manipulation from Kali Linux using PyModbus.
