Description

Azure Web Apps allows sites to run under both HTTP and HTTPS by default. Web apps can be accessed by anyone using non-secure HTTP links by default. Non-secure HTTP requests can be restricted and all HTTP requests redirected to the secure HTTPS port. It is recommended to enforce HTTPS-only traffic.

How to fix?

Set the Microsoft.Web/sites properties.httpsOnly attribute to be true.

Example Configuration

{
  "type": "Microsoft.Web/sites",
  "apiVersion": "2021-02-01",
  "properties": {
    "httpsOnly": true
  }
