Traditional perimeter defense (firewalls shielding internal networks) is obsolete in multi-cloud and remote work environments. Zero-Trust dictates a fundamental mindset shift: "Never Trust, Always Verify." Every container, microservice API call, and administrative SSH session must be cryptographically authenticated and authorized.
1. The 4 Pillars of Kubernetes Zero-Trust
Securing cloud native Kubernetes clusters requires layered defense: Least Privilege IAM (IRSA/Workload Identity), Ephemeral Secrets Storage (HashiCorp Vault), Runtime Container Vulnerability Scanning, and Strict Mutual TLS (mTLS).
