+          Azure audit logs are enabled and managed in the Azure portal. To enable log collection for
+          the Kubernetes master components in your AKS cluster, open the Azure portal in a web
+          browser and complete the following steps:
+          1. Select the resource group for your AKS cluster, such as myResourceGroup. Don't
+             select the resource group that contains your individual AKS cluster resources, such
+             as MC_myResourceGroup_myAKSCluster_eastus.
+          2. On the left-hand side, choose Diagnostic settings.
+          3. Select your AKS cluster, such as myAKSCluster, then choose to Add diagnostic setting.
+          4. Enter a name, such as myAKSClusterLogs, then select the option to Send to Log Analytics.
+          5. Select an existing workspace or create a new one. If you create a workspace, provide
+             a workspace name, a resource group, and a location.
+          6. In the list of available logs, select the logs you wish to enable. For this example,
+             enable the kube-audit and kube-audit-admin logs. Common logs include the kube-
+             apiserver, kube-controller-manager, and kube-scheduler. You can return and change
+             the collected logs once Log Analytics workspaces are enabled.
+          7. When ready, select Save to enable collection of the selected logs.

+          Azure Container Registry
+          If you use Azure Container Registry (ACR) as your container image store, you need to grant
+          permissions to the service principal for your AKS cluster to read and pull images. Currently,
+          the recommended configuration is to use the az aks create or az aks update command to
+          integrate with a registry and assign the appropriate role for the service principal. For
+          detailed steps, see Authenticate with Azure Container Registry from Azure Kubernetes
+          Service.
+          To avoid needing an Owner or Azure account administrator role, you can configure a
+          service principal manually or use an existing service principal to authenticate ACR from
+          AKS. For more information, see ACR authentication with service principals or Authenticate
+          from Kubernetes with a pull secret.

+          Azure Active Directory integration
+          The security of AKS clusters can be enhanced with the integration of Azure Active Directory
+          (AD). Built on decades of enterprise identity management, Azure AD is a multi-tenant,
+          cloud-based directory, and identity management service that combines core directory
+          services, application access management, and identity protection. With Azure AD, you can
+          integrate on-premises identities into AKS clusters to provide a single source for account
+          management and security.
+          Azure Active Directory integration with AKS clusters
+          With Azure AD-integrated AKS clusters, you can grant users or groups access to Kubernetes
+          resources within a namespace or across the cluster. To obtain a kubectl configuration
+          context, a user can run the az aks get-credentials command. When a user then interacts
+          with the AKS cluster with kubectl, they're prompted to sign in with their Azure AD
+          credentials. This approach provides a single source for user account management and
+          password credentials. The user can only access the resources as defined by the cluster
+          administrator.
+          Azure AD authentication is provided to AKS clusters with OpenID Connect. OpenID Connect
+          is an identity layer built on top of the OAuth 2.0 protocol. For more information on OpenID
+          Connect, see the Open ID connect documentation. From inside of the Kubernetes cluster,
+          Webhook Token Authentication is used to verify authentication tokens. Webhook token
+          authentication is configured and managed as part of the AKS cluster.
