Privilege rings for the x86 architecture. The ME is colloquially categorized as ring −3, below System Management Mode (ring −2) and the hypervisor (ring −1), all running at a higher privilege level than the kernel (ring 0).
The Intel Management Engine (ME), also known as the Intel Manageability Engine,[1][2] is an autonomous subsystem that has been incorporated in virtually all of Intel's processor chipsets since 2008.[1][3][4] It is located in the Platform Controller Hub of modern Intel motherboards.
The Intel Management Engine always runs as long as the motherboard is receiving power, even when the computer is turned off. This issue can be mitigated with the deployment of a hardware device which is able to disconnect all connections to mains power as well as all internal forms of energy storage. The Electronic Frontier Foundation and some security researchers have voiced concern that the Management Engine is a backdoor.
Intel's main competitor, AMD, has incorporated the equivalent AMD Secure Technology (formally called Platform Security Processor) in virtually all of its post-2013 CPUs.
