Communication with Minifilter Dirvers RRS feed

  • Question

  • Hi all, I was trying to build a user level application that can communicate with minifilter drivers. At this moment, I need to require the admin permission every time I start the user level application. I want to ask is there any way (or any configuration) that allows me to communicate with my driver without asking for admin every time? Is there any way that I can ask for the permission at the install time and avoid asking for it every time in the future? Thanks a head if any one could help me.

  • Assuming you own the mini-filter and can change the call to FltCreateCommunicationPort (also assuming that is what you are using for communication), then you can modify the OBJECT_ATTRIBUTES to have a security descriptor that will allow communication.
