Abstract
A system and method for validating whether communications between a device driver and a hardware device conform to a communication specification is presented. A validation module obtains a communication specification identifying rules for validating whether communications between a device driver and a hardware device conform to the specification. A redirection module redirects communications between the device driver and the hardware device to the validation module. Based on an individual communication, as well as the context in which an individual communication is made, the validation module validates whether the communication conforms to the communication specification.
