Abstract
A System for providing data security in a first device driver operably installed in a computer operating system having a layered plurality of device drivers (81, 82, 83, 84) for accessing data in a data storage device. The first device driver detects an I/O request, and determines whether the first device driver is functionally uppermost in the layered plurality of device drivers. If the first device driver is functionally uppermost in the layered plurality of device drivers, the method performs the I/O request (80) in the first device driver. If the device driver is not functionally uppermost in the layered plurality of device drivers, the method denies the I/O request in the first device driver, and allows the I/O request to be performed by the next lowest-level driver in the layered plurality of device drivers.
