Brian Schleifer

Senior Systems Security Engineer

 

💡 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.

🧠 Key Terms & Concepts:

·         Risk Management Framework (RMF) – NIST SP 800-37
Referenced in Brian’s experience assessing and implementing cybersecurity controls in defense systems.

·         STPA-SEC – System-Theoretic Process Analysis for Security (MIT)
A systems thinking approach to security based on safety analysis, used by Brian in his academic and professional work.

·         CMMC – Cybersecurity Maturity Model Certification
Brought up during the discussion on compliance and upcoming requirements for government contractors and vendors.

·         Cyber-Physical Systems Overview – NIST
Used to frame how digital systems interact with the physical world — particularly in agriculture, food processing, and defense.

·         IEC 62443 – Industrial Cybersecurity Standard
A referenced framework used across OT/ICS environments to manage and mitigate industrial cybersecurity risk.

·         NIST SP 800-171
Cited when talking about supply chain risk, CMMC alignment, and government-facing compliance.

·         Cyber PHA – Process Hazard Analysis for Cybersecurity
Mentioned by Kristin as a structured, scenario-based approach to evaluating cyber and safety risks together.

·         OSHA – Occupational Safety and Health Administration
Discussed in comparison to cybersecurity maturity. Brian questioned when formal safety began in industry and compared that moment in history to where cybersecurity is now — on the cusp of needing the same level of attention and resource allocation.

·         Glenda Snodgrass – Cybersecurity Training & Talks
Brian mentioned seeing her speak and appreciated how she used real examples—both good and bad—of how to answer security controls effectively.
