Zero Trust at the Edge Webinar: Bringing IT Rigor to Physical Security

Описание: This roundtable brought together experts from government and industry to discuss how to close the gap between IT, OT, and physical security—and how Zero Trust principles can be practically applied at both the near edge and far edge.

Speakers:
Steven Brown – Vice President for Strategy & Business Development, Prometheus Security Group Global (PSG)
Maria Sumnicht – National Cybersecurity Director for Critical Infrastructure, Task Force on Homeland Security
Pierre Bourgeix – CEO and Founder, ESI Convergent
Moderator: Steve Lasky – Editorial Director, SecurityInfoWatch.com

00:00 - Introduction to Zero Trust in Physical Security - Steve Lasky introduces the shift to "never trust, always verify" as physical and digital lines blur.
03:12 - Meet the Panel: Experts in Cyber and Physical Convergence - Introduction of Maria Sumnicht, Pierre Bourgeix (ESI Convergent), and Steven Brown (Prometheus Security Group).
06:21 - Defining "Zero Trust at the Edge" - Why verification must happen at the device level, moving security beyond the server room to the actual point of data origin.
11:45 - The Vulnerability of Legacy Edge Devices - Why traditional IP cameras and sensors are often the "weakest link" and how they create an expanded attack surface for lateral movement.
17:10 - Breaking Down Silos: IT vs. OT Mindsets - The cultural friction between IT departments and Physical Security teams.
24:45 - Continuous Verification and Least Privilege Access - Technical explanation of how to ensure devices only communicate what they are supposed to, only when they are supposed to.
32:15 - The Role of AI and Data Integrity - How Artificial Intelligence changes the risk profile at the edge and why you can't trust AI outputs if the input data isn't authenticated.
37:34 - Deep Dive: How DESI (Digital Encrypted Security Interface) Works - The core technical solution: moving from vulnerable analog resistors to cryptographic, FIPS-compliant device identity.
45:50 - Transitioning from Analog to Digital Authentication - Practical steps for organizations to upgrade existing infrastructure without a complete "rip and replace."
53:10 - Future Proofing with Digital Twins - How a secured edge enables advanced technologies like Digital Twins by providing a "Single Source of Truth."
01:03:05 - Conclusion and Final Takeaways - Closing thoughts on why data protection is now the foundation of physical life safety.
