How to enable Authentication on whole controller and disable only for certain action methods. I want authentication for all resources. If I write something like that:

[Authorize]
public class HomeController : BaseController
{
    //This is public
    [UnAuthorized]
    public ActionResult Index()
    {
        ViewData["Message"] = "Welcome to ASP.NET MVC!";
        return View();
    }
    //This is private resource
    public ActionResult PrivateResource()
    {
        return View();
    }
}

Then anyone can access this resource. Do you have any ideas how to make it better way?
