  • Configure the Auto set content type options property on your instance to prevent MIME confusion attacks.

    Use this property to control the X-Content-Type-Options response HTTP header. The X-Content-Type-Options response HTTP header is used by the server to indicate that the MIME types advertised in the Content-Type headers should be followed. If this property is set to false, then it is possible for an attacker to conduct MIME confusion attacks; if set to true then this header will prevent the browser from interpreting files as anything but the content type in the HTTP headers.

    Warning:
    The value for this property is a no DB override. It can't be altered or overridden.
