OT Network Documentation: How to Read and Create Network Diagrams | OT Security Module 4.11

A network you haven't documented is a network you can't fully protect. This video covers the three types of OT network documentation (physical topology, logical topology, data flow), how to read standard network diagram symbols, what to look for in a diagram from a security standpoint, and how to keep documentation current. Also covers where documentation should be stored so it's accessible during an incident. 🕐 Chapters: 0:00 – Introduction: Why Documentation Is Foundational 0:35 – Three Types of Network Documentation 1:10 – Physical Topology Documentation 1:35 – Logical Topology Documentation 2:00 – Data Flow Documentation 2:35 – Discrepancies as Security Findings 3:00 – Standard Network Diagram Symbols 4:00 – How to Read a Diagram for Security Issues 4:40 – Zone Boundaries and Firewall Placement 5:10 – Devices Spanning Multiple Zones 5:45 – Keeping Documentation Current 6:20 – Where to Store Documentation (Off-Network) 6:35 – Wrap-Up & What's Next Part of Module 4: Network Architecture and Segmentation Full course playlist: [link] If this was useful, subscribe for more content like this. #OTSecurity #IndustrialCybersecurity #ICS #SCADA #NetworkDocumentation
