Policy: Azure > CIS v2.0 > 09 - Application Services > 9.08 - Ensure that 'Java version' is the latest, if used to run the Web App > Attestation

By setting this policy, you attest that you have manually verified that it complies with the relevant section of the CIS Benchmark.

From Azure Portal 1. Login to Azure Portal using https://portal.azure.com 2. Go to App Services 3. Click on each App 4. Under Settings section, click on Configuration 5. Click on the General settings pane and ensure that for a Stack of Java the Major Version and Minor Version reflect the latest stable and supported release, and that the Java web server version is set to the auto-update option.

NOTE: No action is required if Java version is set to Off, as Java is not used by your web app.

From Azure CLI To see the list of supported runtimes:

az webapp list-runtimes

To set latest Java version for an existing app, run the following command:

az webapp config set --resource-group <RESOURCE_GROUP_NAME> --name <APP_NAME>[--java-version <JAVA_VERSION> --java-container <JAVA_CONTAINER> --java-container-version <JAVA_CONTAINER_VERSION> [--windows-fx-version <javaruntime version>] [--linux-fx-version <java runtime version version>]

If creating a new web application to use a currently supported version of Java, run the following commands.

To create an app service plan:

az appservice plan create --resource-group <resource group name> --name <planname> --location <location> [--is-linux --number-of-workers <int> --sku <pricing tier>] [--hyper-v --sku <pricing tier>]

Get the app service plan ID:

az appservice plan list --query "[].{Name:name, ID:id, SKU:sku, Location:location}"

To create a new Java web application using the retrieved app service ID:

az webapp create --resource-group <resource group name> --plan <app serviceplan ID> --name <app name> [--linux-fx-version <java run time version>] [--windows-fx-version <java run time version>]

From PowerShell As of this writing, there is no way to update an existing application's SiteConfig or set a new application's SiteConfig settings during creation via PowerShell.
