ASP MVC Authorize all actions except a few

[Dodo]

I have a controller and I would like to require Authorization for all actions by default except a couple. So in the example below all actions should require authentication except the Index. I don't want to decorate every action with the Authorize, I just want to override the default authorization in certain circumstances probably with a custom filter such as NotAuthorize.\[code\][Authorize]public class HomeController : BaseController{ [NotAuthorize] public ActionResult Index() { // This one wont return View(); } public ActionResult About() { // This action will require authorization return View(); }}\[/code\]
