Cloud-Native Security for Kubernetes
Kubernetes clusters ship with powerful defaults that are insecure by design: open dashboards, broad RBAC, and secrets stored in etcd. Cloud-native security means hardening the control plane, restricting workloads, and scanning images and configs continuously. The cluster is only as safe as its least privileged pod.
要点
- Disable anonymous and unauthenticated access to the API server and dashboards.
- Apply least-privilege RBAC and avoid cluster-admin bindings for application service accounts.
- Enforce pod security standards to block privileged containers and host namespace sharing.
- Scan container images for CVEs and secrets before they reach the registry.
- Encrypt secrets at rest and limit who can read them; prefer external secret stores.
- Network policy defaults to deny; allow only required pod-to-pod and egress paths.
- Monitor audit logs for suspicious API calls, exec into pods, and privilege escalation.
- Keep the control plane and nodes patched and on supported Kubernetes versions.
よくある質問
Is Kubernetes insecure by default?
Its defaults favor usability and compatibility; security requires deliberate hardening of RBAC, pod policy, and network policy.
Do we need a service mesh for security?
Not necessarily. Start with network policies and mTLS where needed; a mesh adds complexity that must be justified.
Where do secrets belong?
In an external secrets manager synced into the cluster, with rotation and audit, not in plain ConfigMaps.
How do we detect cluster compromise?
Through audit log monitoring, runtime detection on nodes, and alerts on privileged exec or unexpected outbound connections.
