In this module you will learn how network segmentation strengthens cybersecurity in industrial environments. You will understand how to design and manage segmented OT networks using tools such as VLANs, DMZs, and firewalls.

You will explore the main industrial communication protocols and their typical vulnerabilities. You will recognize the importance of IT–OT collaboration and best practices for maintaining secure communication and control systems

LEARNING OUTCOMES:

• Explain the concept and objectives of network segmentation in OT environments.
• Describe and compare segmentation models and their practical applications.
• Identify and evaluate solutions such as VLANs, DMZs, and monitoring tools.
• Analyze IT and OT roles in implementing and maintaining segmentation.
• Describe main industrial communication protocols and assess vulnerabilities.
• Interpret real-world case studies involving segmentation and protocol breaches.
