Packet Pushers
Heavy Networking is an unabashedly nerdy dive into all things networking. Described by one listener as "verbal white papers," the weekly episodes feature network engineers, industry experts, and vendors sharing useful information to keep your professional knowledge sharp and your career growing. Hosts Ethan Banks & Drew Conry-Murray cut through the marketing spin to explore what works—and what doesn't—in networking today, while keeping an eye on what's ahead for the industry. On air since 2010, Heavy Networking is the flagship show of the Packet Pushers podcast network.

Heavy Networking 656: Embedding Zero Trust Into Applications
On today's Heavy Networking we look at the idea of embedding zero trust into applications. The way we do cyber security these days has failed in significant ways. What if we could extend the AAA or RBAC model to all applications? Better yet, what if we take the RBAC model, make authentication more robust than username & password, assess endpoint security posture constantly, and evaluate each request individually up at layer 7 for all applications? Guest Galeal Zino has opinions on what embedded zero trust looks like. We discuss.
