Summary

In this podcast, Prabh Nair interviews Bithal Bhardwaj, a seasoned CISO with extensive experience in OT security for critical infrastructure. Bhardwaj shares his journey from IT infrastructure to cybersecurity leadership, emphasizing the importance of asking fundamental questions and understanding business context. The discussion focuses on building cyber resilience for airports and maritime ports, highlighting the differences between IT, OT, and IoT systems. A live miniature model simulates an airport environment, demonstrating how a simple USB device can trigger a chain reaction across multiple sectors, leading to a city-wide blackout. Key topics include network segmentation, zero trust architecture, vendor management, and the challenges of securing legacy systems. The conversation also covers career advice for aspiring CISOs and the importance of crisis management and communication skills. The episode concludes with key takeaways on integrating business context into security operations and the need for continuous learning.
