Kubernetes security starts with access
Most Kubernetes security problems begin with excessive permissions. Least privilege is the starting point.
Production checklist
Use this as a practical baseline.
- Enable least privilege RBAC
- Restrict cluster admin access
- Use network policies
- Scan container images
- Protect secrets
- Use pod security standards
- Enable audit logs
- Limit public ingress
Secure CI/CD for Kubernetes
Your cluster is only as secure as the pipeline deploying into it. Protect credentials, deployment tokens, and production approvals.
Ongoing security
Kubernetes security is continuous. Review permissions, scan images, monitor events, and keep clusters updated.
