Zero Trust Networking for Cloud Workloads

The old castle-and-moat model fails in the cloud. Zero Trust assumes no implicit trust — every request is authenticated, authorised and encrypted, wherever it comes from.

Never trust, always verify

Identity becomes the perimeter. Every service-to-service call carries a verifiable identity (mTLS), and access is least-privilege by default.

Segment everything

Kubernetes NetworkPolicies and a service mesh restrict which workloads can talk to which — lateral movement gets very hard.

kind: NetworkPolicy
spec:
  podSelector: { matchLabels: { app: api } }
  policyTypes: [Ingress]

Continuous verification

Short-lived credentials, device posture and policy engines re-check trust continuously — not just once at login.

Wrapping Up

Zero Trust is a journey, not a product: identity-first access, network segmentation and least privilege make cloud workloads far harder to breach.
