You should look at using roles if you only need basic functionality.

For something more robust, but very time consuming to get started with, look at Rhino Security:

You can check if the user is in a particular role from the view or the controller.

<% if (HttpContext.Current.User.IsInRole("Administrator") ) 
   { 
      Html.RenderPartial("AdminMenus"); 
   } 
   else 
   { 
      Html.RenderPartial("UserMenus"); 
   } 
%>
