The main idea was to allow users to login to the target computer without knowing the correct password and without making any persistent changes to system on which it is executed.
For Data at Rest protection a computer or laptop is simply powered off. The disk now self-protects all the data on it. The data is safe because all of it, even the OS, is now encrypted, with a secure mode of AES, and locked from reading and writing.

Diskless nodes process data, thus using their own CPU and RAM to run software, but do not store data persistently—that task is handed off to a server.This is distinct from thin clients, in which all significant processing happens remotely, on the server—the only software that runs on a thin client is the "thin" (i.e. relatively small and simple) client software, which handles simple input ...
In later computer systems, the BIOS contents are stored on flash memory so it can be rewritten without removing the chip from the motherboard. This allows easy, end-user updates to the BIOS firmware so new features can be added or bugs can be fixed, but it also creates a possibility for the computer to become infected with BIOS rootkits.
