The device driver often needs elevated privileges to read and write memory. Device drivers for physical network interfaces often must have access also to the network interface control registers, directly or via host memory address space mapped to them; sometimes device drivers must as well enable or disable interrupts or other host hardware functions. This usually requires that the device driver has a high level of privilege on the host system.

## 4.4 Use cases
This list of use cases describes several system scenarios for network interfaces, intended as an informative resource to the manufacturer to simplify the choice of a set of security requirements. Each use case is mapped to a security level, which is a collection of risks and the security requirements necessary to mitigate them.
