Zero Trust Architecture Checklist for Production Kubernetes & Microservices

Step-by-step service mesh hardening using Mutual TLS (mTLS), least-privilege RBAC policies, and Vault secret management in Amazon EKS.

1. Why Perimeter Firewalls Fail in Microservices

In distributed microservices, once an attacker breaches an externally facing pod, unencrypted east-west internal traffic allows rapid lateral movement across cluster services.

2. Three Foundational Zero Trust Controls

  • Mutual TLS (mTLS) Everywhere: Wajibkan verifikasi sertifikat dua arah untuk setiap request internal.
  • Least Privilege RBAC: Setiap workload pod hanya memiliki izin akses API yang mutlak diperlukan untuk fungsinya.
  • Ephemeral Secrets: Kredensial database dirotasi otomatis dengan masa aktif singkat via HashiCorp Vault.
