Re: How to access I/O port directly in VC6.0?

If your users run with limited user privileges, and you put an appropriate
security descriptor on the driver, and a program that actually calls port
I/O driver is running as a service (only the GUI will run under the user and
communicate with the service), then a rogue user won't be able to damage
your stuff.

OK. A rogue application makes this call and owns your computer.

There is always a way to make bad things.

But they did a something to protect us from bad guys.

1. Kithara is a device driver protected with the customer number
2. The application has to open the driver with this customer number

So you have no chance to get access to this device driver without the
customer number. We are not really at a level of password security but
I think it's close enough.

Do you really think a self written device driver is more secure? I
would not hold my hands into the fire for my self written device
drivers ;-)

Best regards
