Security Level
Setting
The following settings are possible:
• PCIe and DisplayPort – No Security
Any Thunderbolt device detected that requests a PCI-
express connection will be connected to the system’s PCi-
express bus without requiring any approval by the local
user.
• PCIe and DisplayPort – User Authorization
Each Thunderbolt peripheral includes a unique identifier
which is used to determine if the device has been previously
connected. In the event the user has previously chosen
Always Connect for that particular device, it will
automatically be connected to the PCI-express bus when
subsequently attached.
• PCIe and DisplayPort – Secure Connect
This option offers enhanced protection for authenticating a
previously connected Thunderbolt device beyond relying on
its identifier. The device is provisioned with a key when
initially connected and on subsequent connections, a
challenge-response is implemented to verify the device has
the secret before it is automatically connected to the PCI-
express bus.
• DisplayPort only
Only USB and Display Port functionality will be available via
the Type-C Thunderbolt port. PCI-express will not be
connected from the Thunderbolt device to the internal PCI-
express interface, thus any Thunderbolt device that requires
PCi-express will not function correctly.
