AKS | FIPS

Hi,

The Federal Information Processing Standard (FIPS) 140-2 is a US government standard that defines minimum security requirements for cryptographic modules in information technology products and systems. AKS allows you to create Linux-based node pools with FIPS 140-2 enabled. Deployments running on FIPS-enabled node pools can use those cryptographic modules to provide increased security and help meet security controls as part of FedRAMP compliance. 

In this article, I will show you how you can add a FIPS Node pool to an existing AKS cluster:

Install the aks-preview extension
az extension add --name aks-preview

Update the extension to make sure you have the latest version installed
az extension update --name aks-preview
az feature register --namespace "Microsoft.ContainerService" --name "FIPSPreview"
az feature list -o table --query "[?contains(name,'Microsoft.ContainerService/FIPSPreview')].{Name:name,State:properties.state}"
az provider register --namespace Microsoft.ContainerService
 
Add FIPS Node Pool to an existing AKS cluster
az aks nodepool add \
     --resource-group myResourceGroup \
     --cluster-name myAKSCluster \
     --name fipsnp \
     --enable-fips-image

az aks show --resource-group myResourceGroup --cluster-name myAKSCluster --query="agentPoolProfiles[].{Name:name enableFips:enableFips}" -o table
 Name       enableFips
 ---------  ------------
 fipsnp     True
 nodepool1  False

AKS | Disable Administrator local account

Hi,

When deploying an AKS Cluster, local accounts are enabled by default. Even when enabling RBAC or Azure Active Directory integration, –admin access still exists, essentially as a non-auditable backdoor option. With this in mind, AKS offers users the ability to disable local accounts via a flag, disable-local. A field, properties.disableLocalAccounts, has also been added to the managed cluster API to indicate whether the feature has been enabled on the cluster.

Requirements:

az feature register --namespace "Microsoft.ContainerService" --name "DisableLocalAccountsPreview"

az feature list -o table --query "[?contains(name, 'Microsoft.ContainerService/DisableLocalAccountsPreview')].{Name:name,State:properties.state}"

Disable local account on an existing AKS cluster:

az aks update -g -n --enable-aad --aad-admin-group-object-ids --disable-local

Create a new AKS cluster without any local account:

az aks create -g -n --enable-aad --aad-admin-group-object-ids --disable-local

Azure Policy Search with Azure Graph

Hi!

In this article, I will show you how you can use Azure Graph to check the result of one specific policy across all the subscriptions of your Azure tenant. Before to start let me refine what’s is it?

Azure Resource Graph (ARG) provides an efficient way to query at scale across a given set of subscriptions for any Azure Resource. If you are not familiar, I will recommend you to spend some time to learn it!

In this example, I will create a query to list all the policy and I will extract the policy name, compliance status and the resource id.

policyresources
| where type == "microsoft.policyinsights/policystates"
| extend name = properties['policyDefinitionName']
| extend state = properties['complianceState']
| extend resourceid = properties['resourceId']
| project name, state, resourceid

In this second example, I will create a query to list the compliance status and the resource id of an existing policy

policyresources
| where type == "microsoft.policyinsights/policystates"
| where properties['policyDefinitionName'] == "Name Of your Azure Policy"
| extend state = properties['complianceState']
| extend resourceid = properties['resourceId']
| project state, resourceid
