Policy: Azure > CIS v2.0 > 09 - Application Services > 9.06 - Ensure That 'PHP 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. From Azure Home open the Portal Menu in the top left 2. Go to App Services 3. Click on each App 4. Under Settings section, click on Configuration 5. Click on the General settings pane, ensure that for a Stack of PHP the Major Version and Minor Version reflect the latest stable and supported release.

NOTE: No action is required If PHP version is set to Off or is set with an empty value as PHP is not used by your web app.

From Azure CLI List the available PHP runtimes:

az webapp list-runtimes

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

az webapp config set --resource-group <resource group name> --name <app name>[--linux-fx-version <php runtime version>][--php-version <php version>]

From PowerShell To set latest PHP version for an existing app, run the following command:

Set-AzWebApp -ResourceGroupName <resource group name> -Name <app name> -phpVersion <php version>

NOTE: Currently there is no way to update an existing web app Linux FX Version setting using PowerShell, nor is there a way to create a new web app using PowerShell that configures the PHP runtime in the Linux FX Version setting.

Once verified, enter the date that this attestation expires. Note that the date can not be further in the future than is specified in report level Maximum Attestation Duration policy. Set to a blank value to clear the attestation.
