you should create a basecontroller and inherit other controlers from base controller and then check whether the session is null or not to authenticate users.

 public class BaseController : Controller
 {
        protected override void OnActionExecuting(ActionExecutingContext filterContext)
        {
            if (Session["User"]== null)
            {
               filterContext.HttpContext.Response.Redirect("/somepage");
        }

 }

public class SomeController : BaseController
{

}
