Huawei EulerOS 2.0 is a general purpose, multi-user, multi-tasking Linux based operating system. It provides a platform for a variety of applications, including services on cloud environment. Huawei EulerOS 2.0 evaluation covers a potentially distributed network of systems running the evaluated version and its configurations as well as other peer systems operating within the same management domain. The
hardware platforms selected for the evaluation consist of machines that are available on market when the evaluation has completed and to remain available for a substantial period of time afterwards.

The TOE Security Functions (TSFs) consist of functions of Huawei EulerOS 2.0 that run in kernel mode plus some trusted processes running in user mode. These are the functions that enforce the security policy as defined in the Security Target. Tools and commands executed in user mode that are used by an administrative user need also to be trusted to manage the system in a secure way, but they are not  considered to be part of the TSF, just as with other operating system evaluations.

The hardware, BIOS firmware and potentially other firmware layers between the hardware and the TOE, are considered to be part of the TOE environment.
