WAPs, Modems, NICs & Why SCADA is Networked | OT Security Module 1.4

In this video, we finish rounding out the hardware picture with a few more devices you'll encounter in industrial environments — wireless access points, modems, and network interface cards — and then tackle a question that's critical for anyone working in OT security: why is SCADA networked in the first place? We cover what a wireless access point is and why it's another entry point into your network, what a modem does and how it differs from a router, and what a NIC and MAC address are. We also cover the real operational reasons OT systems get connected — remote monitoring, vendor access, enterprise integration, and cloud historians — and why the air gap that used to protect OT systems is largely gone. By the end of this video, you'll understand that connectivity creates real business value alongside potential attack paths, and that managing that risk is what this entire course is about. 🕐 Chapters: 0:00 – Introduction: finishing the hardware picture & why SCADA is networked 0:20 – Other hardware worth knowing 0:23 – Wireless access points (WAP/AP) explained 0:34 – How APs connect wireless devices to your wired network 0:41 – WAPs as entry points into the network 0:54 – What is a modem?
