• How do we control and segment
the device and users?
• How do we provide consistent
policy across the network?

• EAP Chaining ties both the machine and user credentials to the device, thus
the "owner" is using a corporate asset
Use Cases:
• Restrict use of personal laptops on a corporate network
• Corporate mandates where a corporate asset must be used and the user must
be authorized.
