• Answer:

  You can use the AuthroizeAttribute either on the Controller level: [Authorize] public class HomeController : Controller { // Now all actions require authorization } or Action level: public class HomeController : Controller { public ActionResult Index() { // Does not require authorization } [Authorize] public ActionResult PrivateThing() { // requires authorization } } You can pass usernames, roles, etc to the http://msdn.microsoft.com/en-us/library/system.web.mvc.authorizeattribute.aspx as well for finer grained authorization. If, however, the default AuthroizeAttribute doesn't work for you you can always roll your own by inheriting from AuthorizeAttribute: public CustomAuthorizeAttribute : AuthorizeAttribute { public override void OnAuthorization(AuthorizationContext filterContext) { base.OnAuthorization(filterContext); // Auhtorization logic here } }
