OT/ICS Hacking Lab: Compromising Modbus TCP

Uncover the security vulnerabilities embedded within industrial automation with this targeted course on compromising and securing Modbus TCP networks. Designed for professionals operating at the intersection of IT and Operational Technology (OT), this curriculum bridges the gap between legacy industrial protocols and modern cybersecurity realities.

Participants will dissect the structural design of Modbus TCP to understand why its lack of authentication makes it a primary target for communication disruptions. Through structured analysis, you will learn to map industrial networks, intercept protocol traffic, and identify critical security gaps in programmable logic controllers (PLCs) and supervisory systems.

Moving beyond theoretical risk, the course delivers actionable defense strategies. Exploration of practical hardening techniques, network segmentation principles, and monitoring solutions will demonstrate how to detect anomalies without disrupting live operations. By investigating how communication paths can be manipulated, participants will gain the forensic insights needed to build resilient industrial control systems. Equipping students with both offensive perspectives and defensive tactics, this course prepares professionals to safeguard critical infrastructure against emerging cyber threats.

The curriculum emphasizes the implementation of deep packet inspection and the deployment of industrial firewalls to mitigate unauthorized command execution. Practical modules cover the configuration of secure gateways and the use of encryption wrappers to protect plain-text protocol traffic. Mastery of these skills ensures that critical processes in sectors such as energy, manufacturing, and water utilities remain stable under adversarial conditions. Upon completion, graduates will possess a comprehensive toolkit for auditing industrial environments and advocating for security-first architectures in legacy deployments. This training is essential for anyone responsible for the uptime and integrity of modern industrial sites where traditional OT security measures may fall short.
