Industrial Control Systems (ICS) are the silent machines that control the world all around us. ICS systems are used to control elevators, subways, building HVAC systems and the electricity we use. The convergence of information technology (IT) and operational technology (OT) in the ICS marketplace has been taking place over the last 20 years. This convergence, while increasing ICS operational efficiency, is also increasing cyber risk. In this course, you will learn about how to identify the protocols being used in OT networks, how to decode them and the tools and procedures to perform network assessments on these networks. AGENDA: 1. Control System Defined 2. Control System Networks vs IT Networks (CIA vs AIC) 3. Overview of Control System vendors/protocols 4. What's available for ICS Systems in Wireshark and Kali Linux? 5. LAB: How to Decode Modbus 6. LAB: Sniffing and Assessing an ICS Network REQUIREMENTS: Students should bring the a Llaptop with VM Workstation and Wireshark installed.
