Episode notes

What happens when a single lost network packet can disrupt hours of manufacturing? Recorded at Cisco Live, this episode features John Hoenemier, Director of Network Security Operations at GlobalFoundries, one of the world's leading semiconductor manufacturers. While most people think about microchips only when they buy a smartphone, laptop, car, or connected device, the reality is that modern life depends on a vast ecosystem of manufacturing facilities operating around the clock with extraordinary levels of precision. During our conversation, John explains why semiconductor manufacturing is one of the most demanding operational environments in the world. Production runs continuously throughout the year, and even minor disruptions can have significant consequences. In this environment, the network serves as the digital nervous system of the factory floor, connecting equipment, systems, data, and people in real time. We discuss the challenges of maintaining resilience in an environment where downtime is rarely an option.
