Thunderbolt 
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.
