I got the similar phone interview question from Qualcomm last week, and I think "via system call" is right.

It is obviously done using system calls :) Adding more details specific to Windows:
Following are the bug guys involved here:
1. Kernel Mode driver (Mini Filter Driver)
2. User Mode application
3. Windows Filter Manager

The bidirectional communication between the driver and application takes place via a serial port created by the driver. The security of the serial port is determined by the driver. The driver listens to this port. User mode application creates connection with this port. Windows Filter manager notifies this to the driver. And Filter manager provides appropriate APIs for the user mode app and driver to communicate. Further details can be seen in MSDN.
