Zero trust is a design posture: authenticate every interaction, authorize every request, and assume the network is hostile by default.
01. Identity-first controls
Focus on workload identity, service-to-service auth, and short-lived credentials. Perimeter controls alone don’t scale with modern architectures.
02. Policy everywhere
Define access policies close to the resource, use least privilege, and make authorization decisions observable and testable.
03. Auditability as a feature
Build audit trails into the system: who accessed what, when, and why. Good security is measurable security.
