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 AuthorizeAttribute constructor 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
    }
}
