Security Best Practices
Essential security configurations for production Kubernetes clusters.
Cluster Hardening
- Enable audit logging for all API server requests
- Implement pod security admission (restricted profile)
- Disable anonymous authentication
- Use network policies to restrict pod-to-pod traffic
- Enable encryption at rest for etcd
Workload Security
- Run containers as non-root users
- Use read-only root filesystems
- Drop all capabilities and add only required ones
- Scan images for vulnerabilities before deployment
- Implement resource limits and quotas
Access Control
- Follow least-privilege RBAC principles
- Use namespaces for multi-tenancy isolation
- Rotate service account tokens regularly
- Implement MFA for cluster access
- Audit and review permissions quarterly
