Azure audit appservice http 2 disabled remediation

Using Console

To remediate the HTTP 2.0 disabled misconfiguration in Azure using the Azure console, you can follow these steps:

Log in to the Azure portal and navigate to the App Service that needs to be configured.
Under the Settings section, select Configuration.
Scroll down to the General settings section, and locate the HTTP version configuration.
Change the HTTP version configuration to “2.0” to enable HTTP 2.0.
Click Save to apply the changes.
Restart the App Service to ensure that the changes are applied.
Once the App Service is restarted, verify that HTTP 2.0 is enabled by accessing the application through a web browser and checking the network tab of the developer tools.

By following these steps, you can remediate the HTTP 2.0 disabled misconfiguration in Azure using the Azure console.

Using CLI

To remediate HTTP 2.0 disabled misconfiguration in Azure using Azure CLI, you can follow the below steps:Step 1: Open Azure CLI and login to your Azure account.

az login

Step 2: Check the current status of HTTP 2.0 on the web app.

az webapp show --resource-group <resource-group-name> --name <web-app-name> --query http20Enabled

Step 3: If the output of the above command is false, then HTTP 2.0 is disabled for the web app. To enable it, run the below command:

az webapp update --resource-group <resource-group-name> --name <web-app-name> --http20-enabled true

Step 4: Verify that HTTP 2.0 is enabled by running the below command:

az webapp show --resource-group <resource-group-name> --name <web-app-name> --query http20Enabled

Step 5: Once verified, you have successfully remediated the HTTP 2.0 disabled misconfiguration for your Azure web app.Note: Replace <resource-group-name> and <web-app-name> with your actual resource group and web app name respectively.

Using Python

To remediate the HTTP 2.0 Disabled misconfiguration in Azure using Python, you can use the Azure SDK for Python. Here are the step-by-step instructions:

Install the Azure SDK for Python by running the following command in your terminal:
pip install azure

Import the necessary modules:

from azure.mgmt.web import WebSiteManagementClient
from azure.common.credentials import ServicePrincipalCredentials

Authenticate with Azure using a service principal:

credentials = ServicePrincipalCredentials(
    client_id='<your_client_id>',
    secret='<your_client_secret>',
    tenant='<your_tenant_id>'
)

Create a WebSiteManagementClient object:

client = WebSiteManagementClient(credentials, '<your_subscription_id>')

Get the resource group and site name for the web app:

resource_group_name = '<your_resource_group_name>'
site_name = '<your_site_name>'

Get the current site configuration:

site_config = client.web_apps.get_configuration(resource_group_name, site_name)

Check if HTTP 2.0 is already enabled:

if site_config.http20_enabled:
    print('HTTP 2.0 is already enabled.')
else:
    # Enable HTTP 2.0
    site_config.http20_enabled = True
    client.web_apps.update_configuration(resource_group_name, site_name, site_config)
    print('HTTP 2.0 has been enabled.')

This code checks if HTTP 2.0 is already enabled. If it is, it prints a message saying so. If it is not, it enables HTTP 2.0 and prints a message saying it has been enabled.

Run the code and verify that HTTP 2.0 has been enabled for your web app.
python remediate_http2_disabled.py

Using Terraform

resource "azurerm_app_service" "APP_SERVICE_NAME" {
  name                = "APP_SERVICE_NAME"          # replace with your App Service name
  location            = azurerm_resource_group.RG_NAME.location
  resource_group_name = azurerm_resource_group.RG_NAME.name
  app_service_plan_id = azurerm_app_service_plan.PLAN_NAME.id

  site_config {
    http2_enabled = true
    # keep any other existing settings here (e.g., linux_fx_version, always_on, etc.)
  }

  # keep other existing blocks (app_settings, identity, auth_settings, etc.) as needed
}

This change does not force replacement of the App Service; it updates the existing site configuration in-place.To verify, terraform plan should show an in-place update on azurerm_app_service.APP_SERVICE_NAME with site_config.0.http2_enabled changing from false (or null) to true.
