Key Components of an Effective OT Network Architecture
Summary: Dragos and the SANS Institute published the second entry in their OT Cybersecurity Fundamentals blog series, describing OT network architecture through the Purdue Model, which divides industrial environments into five levels from Level 0 to Level 4, with enterprise IT at Level 4 and OT networks below. The post covers OT components including ICS and SCADA systems and states that an effective OT security program rests on five critical controls, though the text does not name them.
Key Takeaway: The article frames IT-OT convergence and escalating cyber threats as the reason OT architecture now needs continuous monitoring, IT/OT threat detection, and risk-based vulnerability management - controls built for networks that support real-time physical processes across manufacturing, utilities, and transportation.
