Method for measuring device driver hardened levels

Disclosed is a method for measuring device driver hardened levels. Benefits include improved reliability.


Description

              Device driver hardened levels are a set of levels that describe the extent and type of hardening for device drivers. Each level contains a set of guidelines. The device driver software is designed and coded according to the guidelines for the particular level that the device driver supports (see Figure 1). The hardening is tested to the level that the device driver supports.

Advantages

              Conventionally, there is no way to check or measure a hardened device driver. It can be a binary claim, meaning that it is or is not hardened but there are no guidelines for completeness. Additionally, if a device driver claims to be 80% hardened, there is no way to measure it.

      The disclosed method clearly describes the guidelines that must be met by the device driver for each level of hardening. Using the levels and guidelines within them, the device driver can be designed, implemented, tested, and measured to meet specified hardening levels with 100% accuracy.
