💡 What can the food industry learn from 25+ years of defense cybersecurity experience?

In this episode of the Bites and Bytes Podcast, host Kristin Demoranville talks with Brian Schleifer, a cybersecurity expert with a career spanning the U.S. Air Force, Department of Defense systems, and advanced cyber-physical risk management. Together, they unpack how the principles of defense cybersecurity, from risk modeling to system resilience, can help protect the food and agriculture sector, one of the most vulnerable critical infrastructures.

This episode explores:

✅ What precision agriculture and defense systems have in common

✅ Why autonomous tractors and food processing systems are prime targets

✅ The reality of protecting proprietary food data and recipes

✅ Cyber-physical risks in modern farming and food production

Whether you work in OT, IT, food safety, risk management, or supply chain, this episode is packed with real talk and relatable analogies (plus homemade tortillas and schnitzel get shoutouts). Tune in to hear why safety and security must go hand in hand — and what it really means to secure the systems that feed the world.
