Nice links, but it is 2003 and even MSDN says they are not accurated anymore.

If you want to restrict external users for access your web service then you can restrict external users ip address

http://stackoverflow.com/questions/1075618/limit-access-of-asmx-web-service-to-specific-ip-addresses/1075639#1075639[^]

if also can protect by code

C#

if (!Request.IsLocal)
{
    Response.StatusCode = 401;
    Response.StatusDescription = "Unauthorized";
    return null;
}

You need to check it from your every web method. Besides that you can write custom base webservice method and implement it there so that from every web method call it is checked.

If your web service is wcf service then you can implement the following stratigy
