Industrial systems power everything from manufacturing plants to power grids, oil & gas facilities, automotive factories, and critical infrastructure. Understanding how these systems are built is the first step toward securing OT environments. In this video, I break down Section 1 from my complete OT Cyber Security Course, available on Udemy in both Hindi and English. You will learn: * What OT system architecture looks like * How client, server, and database systems work in industrial environments * Differences between IT and OT system design * Why architecture is foundational to OT cybersecurity * Real-world relevance of industrial system components This is a preview video from my full course. If you want hands-on labs, ICS attack demonstrations, governance workflows, and practical OT real-world scenarios, you can access the complete course here: Enroll in the Full OT Cyber Security Course in English https://www.udemy.com/course/ot-security-ics-scada-purdue-model-mitre-ics-pentest/?referralCode=5D109105FADDEB05184C If you find this useful, subscribe to the channel and explore more OT and cybersecurity topics. #otsecurity #ics #industrialsecurity #criticalinfrastructure #scada #plc #cybersecurity #industrialcontrolsystems
