Oracle System Assistant contains a bootable root environment

Oracle System Assistant is an application that runs on a preinstalled, internal USB flash drive. It is built on top of a bootable Linux root environment. Oracle System Assistant also provides the ability to access its underlying root shell. Users who have physical access to the system, or who have remote KVMS (keyboard, video, mouse, and storage) access to the system through Oracle ILOM, will be able to access Oracle System Assistant and the root shell.

A root environment can be used to change system configuration and policies, as well as to access data on other disks. It is recommended that physical access to the server be protected and that the administrator and console privileges for Oracle ILOM users be assigned sparingly.
