How Segmentation Stops Attackers: Containment, Detection & Blast Radius | OT Security Module 4.3

Segmentation doesn't just keep attackers out—it limits what they can do once they're in. This video covers what network segmentation actually does during an active attack: slowing lateral movement, reducing blast radius, creating detection opportunities, and buying defenders time to respond. We examine real cases including Stuxnet and the 2015 Ukraine power grid attack to show what segmentation would (and wouldn't) have changed. 🕐 Chapters: 0:00 – Introduction 0:20 – How Segmentation Stops Lateral Movement 1:00 – The Fire Compartmentalization Analogy 1:45 – Segmentation Buys Defenders Time 2:20 – Lessons from Stuxnet 2:55 – The 2015 Ukraine Power Grid Attack 3:30 – Segmentation Creates Detection Points 4:20 – Zone Boundaries as Choke Points 4:50 – Wrap-Up & What's Next (IT/OT Convergence) 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 #Stuxnet #NetworkSegmentation
