You can follow the question or vote as helpful, but you cannot reply to this thread. It is to ensure that the boot process starts from a trusted combination of hardware and software, and continues until the operating system has fully booted and applications are running. The one-size-fits-all specification consists of three parts. It permits decice ANDing and ORing of these authorization primitives to construct complex authorization policies.
