Mutual TLS (mTLS) with Service Mesh (Istio / Linkerd)
- Both client and server authenticate each other using X.509 cryptographic certificates rotated automatically by the service mesh control plane.
- All internal pod-to-pod network traffic is encrypted with TLS 1.3.
- Combined with short-lived JWT scoped tokens to verify service-level authorization.
