### Description{% #description %}

This check ensures that Azure Web App Services are configured to accept only HTTPS traffic by setting the `https_only` attribute to `true`. Allowing HTTP traffic by setting `https_only = false` exposes the web application to potential security risks, including interception of sensitive data through unencrypted connections. To enforce secure communications, configure your Terraform resource as follows:

```
resource "azurerm_app_service" "example" {
  name                = "example-app-service"
  location            = azurerm_resource_group.example.location
  resource_group_name = azurerm_resource_group.example.name
  app_service_plan_id = azurerm_app_service_plan.example.id

  site_config {
    dotnet_framework_version = "v4.0"
    scm_type                 = "LocalGit"
  }

  https_only = true

  connection_string {
    name  = "Database"
    type  = "SQLServer"
    value = "Server=some-server.mydomain.com;Integrated Security=SSPI"
  }
}
```
