-# Dashboard for MVC - How to create a custom dashboard controller
+# Dashboard for MVC - How to Create a Restricted Dashboard Controller
 
-The example shows how to create a custom dashboard controller for the [Web Dashboard](https://docs.devexpress.com/Dashboard/16977/web-dashboard/aspnet-mvc-dashboard-extension) in an ASP.NET MVC application.
+You can do one of the following to prevent inadvertent or unauthorized dashboard modifications and protect dashboards stored on a server:
 
-Inherit the [DashboardController](https://docs.devexpress.com/Dashboard/DevExpress.DashboardWeb.Mvc.DashboardController) class to create a custom dashboard controller. Pass its name to the [RouteCollectionExtension.MapDashboardRoute](https://docs.devexpress.com/Dashboard/DevExpress.DashboardWeb.Mvc.RouteCollectionExtension.MapDashboardRoute(System.Web.Routing.RouteCollection-System.String-System.String-System.String--)) method when you configure routing and to the [DashboardExtensionSettings.ControllerName](https://docs.devexpress.com/Dashboard/DevExpress.DashboardWeb.Mvc.DashboardExtensionSettings.ControllerName) property when you configure a control on the page. 
+- Handle the [DashboardConfigurator.VerifyClientTrustLevel](https://docs.devexpress.com/Dashboard/DevExpress.DashboardWeb.DashboardConfigurator.VerifyClientTrustLevel) event and set [e.ClientTrustLevel](https://docs.devexpress.com/Dashboard/DevExpress.DashboardWeb.VerifyClientTrustLevelEventArgs.ClientTrustLevel) to `Restricted` mode.
+- Derive a custom dashboard controller from [RestrictedDashboardController](https://docs.devexpress.com/Dashboard/DevExpress.DashboardWeb.Mvc.RestrictedDashboardController) instead of [DashboardController](https://docs.devexpress.com/Dashboard/DevExpress.DashboardWeb.Mvc.DashboardController).
 
-In this example, the custom controller name is `DefaultDashboard`.
+The example shows how to create a restricted dashboard controller for the [Web Dashboard](https://docs.devexpress.com/Dashboard/16977/web-dashboard/aspnet-mvc-dashboard-extension) in an ASP.NET MVC application.
+
+## Example Description
 
+Inherit the [DashboardController](https://docs.devexpress.com/Dashboard/DevExpress.DashboardWeb.Mvc.DashboardController) class to create a custom dashboard controller. Add its name (without a `Controller` prefix) to the following places:
+- The [RouteCollectionExtension.MapDashboardRoute](https://docs.devexpress.com/Dashboard/DevExpress.DashboardWeb.Mvc.RouteCollectionExtension.MapDashboardRoute.overloads) method when you configure routing;
+- The [DashboardExtensionSettings.ControllerName](https://docs.devexpress.com/Dashboard/DevExpress.DashboardWeb.Mvc.DashboardExtensionSettings.ControllerName) property when you configure a control on the page. 
+
+In this example, the custom controller name is `DefaultDashboard`.
