KitKat 4.4 :: How To Deny Or Restrict Network Access To A Specific Application

I wanted to restrict an application from accessing network, so that application does not upload or download. Basically to stop rouge application from suspicious network activity.

I understand Android provides a way to limit/restrict network access for Mobile network, from Settings --> Data Usage screen. But I'm looking for a way to completely restrict network access (both mobile and WiFi networks) to any particular application.

I'm using Moto G, Android Kitkat
