Fascinating, Knox appears to be the dogs danglies when it comes to security on Android devices. For phones with Knox up and running from a server they have a white list of applications that are allowed. Applications can have their permissions recindered remotely and basically Knox has the US military's approval. All good stuff for Samsung.
