Securing AKS Clusters
Security in Azure Kubernetes Service (AKS) requires a multi-layered approach covering cluster, node, pod, and network levels.
Security Layers
- RBAC: Kubernetes RBAC integrated with Azure AD for fine-grained access control
- Network Policies: Calico or Azure NPM for pod-to-pod traffic control
- Pod Security: Pod Security Standards (restricted, baseline, privileged)
- Workload Identity: Azure AD Workload Identity for secure service-to-service auth
- Secrets Management: Azure Key Vault CSI driver for secret injection
Best Practices
Enable Microsoft Defender for Containers, use private clusters, rotate credentials regularly, and scan container images before deployment.
