Re: programmatically install a class filter driver

If your filter is creating a control device for communication, there are
two simple things to do. Use IoCreateDeviceSecure to create the control
device and specify security such that only a unique account that you set up
for your application can access it. Second, when creating the control
device specify exclusive so only one copy of the application can open it.

There are a lot of other schemes that are either more complex, such as
checking the security on the open in the driver yourself, or not really
effective, such as checking what the applications name is (this can easily
be faked). The IoCreateDeviceSecure is the simple model that most people
use.

Hi all ,
I have install my filter driver fdriver.sys as upper filter on disk.sys
using inf file( start type : SERVICE_BOOT_START ) . Now i want its
personal interaction from my win32 application. So that fdriver.sys
will not receive request from any application other than my
application.So,basically i want to write a appliction that will be the
only application that can interact with my driver. Can anybody suggest
something.
Thanks in advance
Nidhi
