Wi-Fi Security in Industrial OT: Risks, Standards & Best Practices | OT Security Module 4.9

Wi-Fi is increasingly common on the plant floor—mobile HMIs, handheld scanners, wireless instrumentation. But wireless introduces risks that don't exist in wired networks. This video covers Wi-Fi encryption standards (WEP, WPA, WPA2, WPA3), how to architect wireless VLANs for OT, the unauthorized access point threat, and 802.1X port-based access control. 🕐 Chapters: 0:00 – Introduction to Wireless in OT 0:30 – Why Wireless Is Different from Wired 0:55 – WEP: Completely Broken 1:30 – WPA and Why It's Also Unacceptable 1:50 – WPA2 and WPA3: Current Standards 2:20 – Dedicated Wireless VLANs for OT 3:00 – Separate SSIDs for Different User Populations 3:45 – The Unauthorized Access Point Threat 4:45 – Contractor Hotspot Bridging Risk 5:20 – Wireless Surveys and Detection 5:45 – 802.1X Port-Based Access Control 6:30 – Disabling Unused Switch Ports 7:00 – 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 #WiFiSecurity #WPA3
