SN 1068: The Call Is Coming From Inside the House - Live From Zero Trust World 2026

Author: TWiT March 5, 2026 Duration: 51:55

Steve Gibson and Leo Laporte host a special episode of Security Now live from ThreatLocker's Zero Trust World 2026 in Orlando, Florida.

The final frontier of security is internal. Today, we have the tools, techniques and technologies to thwart attacks originating from outside our perimeter. We're now good at protecting our borders. But major high profile breaches occurring over the past several years have revealed that insufficient attention has been given to the security of our internal systems and networks. Today's greatest security weaknesses result from decades of system design, deployment and policy that have placed far too much trust on the conduct of those on the inside, behind our borders. Whether deliberate, inadvertent, or externally penetrating, the greatest challenge we now face is that of designing and deploying our internal security with strict adherence to the principles of least privilege and zero trust.
