🎙️ Candidate Opening & Architectural Context
""Least-privilege access, encrypted secrets in transit/at rest, and continuous vulnerability scanning are foundational. The interviewer is testing: Modern network security paradigms, perimeter-less security.. I structure my answer around systematic triage first, root cause analysis second, and permanent remediation third.""

Production Solution & Architecture
Zero Trust is a security model built on the principle of "Never trust, always verify." Traditionally, corporate networks used a "Castle and Moat" design: anyone outside the VPN was a threat, but anyone inside the network (or on the VPN) was trusted by default. Zero Trust assumes the network is *already* compromised. It dictates that no entity (user, device, or microservice)—whether deeply internal or remote—is trusted by default. Every single request, between any two services, must be explicitly authenticated, authorized, and continuously validated before access is granted.
