There is no automated way to do this at the moment. There will be in the future. Today one way to do it is to set up Configuration >> Automatically Allow Devices Access to "no" . Then each new device that enrolls can be allowed access if it is not jailbroken or unenrolled if it is.
The allow/unenroll step is manually done by the admin
