Azure AKS Security Best Practices: How to Keep Your Cluster Safe
As organizations move to Azure Kubernetes Service (AKS) for container orchestration, it’s important to be aware of the potential security risks and how to best mitigate them. This guide provides an overview of AKS security best practices, including how to secure your cluster control plane and worker nodes, as well as how to deploy and manage applications securely. By following these best practices, you can help keep your AKS cluster safe and secure.
Azure AKS Cluster Security
Azure AKS Cluster Security is a set of tools and services that help you secure your Azure Kubernetes Service (AKS) cluster. AKS Cluster Security includes:
– Identity and Access Management (IAM): IAM controls who can access your AKS cluster and what they can do. IAM can be used to create and manage users, groups, and roles.
– Network security: Network security controls traffic in and out of your AKS cluster. Network security can be used to create and manage firewalls, network security groups, and network policies.
– Container security: Container security controls the security of the containers in your AKS cluster. Container security can be used to create and manage container images, container registries, and container runtime environments.

In order to harden your Azure AKS cluster, you need to take a few steps to secure both the control plane and the data plane.
On the control plane, you need to enable Azure RBAC and set up network policies. This will give you fine-grained control over who can access your cluster and what they can do.
On the data plane, you need to encrypt your data at rest and in transit. You can do this with Azure Disk Encryption and Azure Network Security Groups.
Both of these steps will help to secure your Azure AKS cluster and prevent unauthorized access.
Azure AKS Cluster Vulnerabilities
Azure AKS is a managed Kubernetes service that lets you deploy and manage containerized applications at scale. While AKS offers many benefits, it also introduces some new security risks that you need to be aware of.
One potential security issue is that AKS clusters are often deployed in public subnets, which makes them accessible to anyone with internet access. This means that if your cluster is not properly secured, it could be exploited by malicious actors.
Another issue to be aware of is that AKS nodes are often deployed with weak passwords or no password at all. This can allow attackers to gain access to your cluster and its resources if they can guess or brute-force the password.
Finally, AKS clusters can also be vulnerable to denial of service attacks. This is because the Kubernetes API server is a single point of failure for the entire cluster. If it goes down, the entire cluster will go down with it.
To protect your Azure AKS cluster from these and other security risks, it’s important to deploy it in a private subnet, use strong passwords for all cluster components, and deploy a denial of service protection solution.
Azure AKS Cluster Permissions
When you create an Azure Kubernetes Service (AKS) cluster, you can control access to the cluster by using role-based access control (RBAC). This allows you to grant users and applications only the permissions they need to perform their tasks. For example, you can give a user permission to view information about the cluster but not create or delete resources.
When you create an AKS cluster, Azure RBAC is enabled by default. The following built-in roles are available:
Cluster Administrator: Can manage all resources in the cluster, including adding and removing nodes.
Cluster User: Can access the cluster but cannot make any changes.
If you need more granular control over permissions, you can create custom roles. For more information, see Create a custom role for Azure Kubernetes Service.
Azure AKS Cluster Identity and Access Management
Azure offers several options for managing identities in AKS clusters. The most common option is to use Azure Active Directory (AD) to manage identities. Azure AD is a cloud-based identity and access management service that provides a single sign-on experience for users and gives administrators control over access to Azure resources. Other options for managing identities in AKS clusters include using Azure Active Directory Domain Services or using a third-party identity provider such as Ping Identity.
Azure AKS Cluster Network Security
Azure AKS Cluster Network Security:
Azure AKS provides a managed Kubernetes service that makes it easy to deploy and manage containerized applications. AKS reduces the complexity and operational overhead of managing Kubernetes by offloading much of that responsibility to Azure. As a managed Kubernetes service, Azure AKS provides a number of features and benefits to help you secure your applications.
One of the key benefits of Azure AKS is that it integrates with Azure Active Directory (AD) for authentication and authorization. This means that you can use your existing AD credentials to access the AKS cluster and its applications. Azure AD also provides role-based access control (RBAC) for AKS, which allows you to granularly control who has access to what resources.
In addition, Azure AKS uses Network Security Groups (NSGs) to control traffic to and from the cluster. By default, only traffic from within the same virtual network as the AKS cluster is allowed. This can be further restricted by configuring NSGs to allow only specific sources or destinations.
Finally, Azure AKS encrypts all data in transit using Transport Layer Security (TLS). This includes communication between the cluster nodes, as well as between the cluster and client applications. TLS ensures that data cannot be intercepted or tampered with in transit.
