The traditional "castle-and-moat" security model is obsolete in today's distributed environments. The Zero Trust model fundamentally shifts focus from network location to identity verification and explicit authorization for every access request.
This paradigm change has significant implications not just for security teams, but also for developers and operations personnel who build and manage applications.

In this session, we will dive into the technical pillars enabling Zero Trust, exploring authentication (AuthN) and authorization (AuthZ) mechanisms, and how they integrate seamlessly with modern Identity Providers (IDPs), OIDC, and OAuth standards. We'll examine how technologies like WireGuard-based clients (Cloudflare WARP, Twingate, Tailscale) replace traditional VPNs for secure resource access without placing users directly on the network. Finally, we'll demonstrate practical implementation patterns, including defining fine-grained access policies, leveraging secure tunnels for connecting applications (like Kubernetes clusters), and managing this infrastructure using Infrastructure as Code (Terraform) and service discovery patterns (like Helm charts integrating with internal DNS/service mesh). Join us to understand how to build and operate applications securely in a world where trust is never assumed.
