Explanation:
* Workplace Join leverages a feature included in the Active Directory Federation Services (AD
FS) Role in Windows Server 2012 R2, called Device Registration Service (DRS). DRS provisions
a device object in Active Directory when a device is Workplace Joined. Once the device object is
in Active Directory, attributes of that object can be retrieved and used to provide conditional
access to resources and applications. The device identity is represented by a certificate which is
set on the personal device by DRS when the device is Workplace Joined.
* In Windows Server 2012 R2, AD FS and Active Directory Domain Services have been extended
to comprehend the most popular mobile devices and provide conditional access to enterprise
resources based on user+device combinations and access policies. With these policies in place,
you can control access based on users, devices, locations, and access times.
