Security Baselines

[princzsaharan]

Hi, I'm having an issue after enabling the baseline securities. When we connect our laptop to the docking station via the Thunderbolt port, the peripherals (mouse, keyboard, and network connection) get blocked.

We suspected the policy "Disable new DMA devices when this computer is locked," but disabling it didn't help.

Does any body have any idea, which policy it might be blocking the peripherals ? this is a headache to find.

Hi,

Yes unfortunately, it isn't easy to troubleshoot.
I have heard that the "Direct Memory Access Guard" could block Thunderbolt docks. I can see that you have already looked at the DMA policy, but I would recommend you look at that.
