Umbrella marketing term by Intel From Wikipedia, the free encyclopedia
Intel vPro technology is an umbrella marketing term used by Intel for a large collection of computer hardware technologies, including VT-x, VT-d, Trusted Execution Technology (TXT), and Intel Active Management Technology (AMT).[1] When the vPro brand was launched (circa 2007), it was identified primarily with AMT,[2][3] thus some journalists still consider AMT to be the essence of vPro.[4]

Intel vPro is a brand name for a set of PC hardware features. PCs that support vPro have a vPro-enabled processor, a vPro-enabled chipset, and a vPro-enabled BIOS as their main elements.[2][3][5][6][7][8]
A vPro PC includes:
The 12th generation of Intel Core processors introduced four distinct platforms: vPro Essentials, vPro Enterprise for Windows, vPro Enterprise for Chrome and vPro Evo Design.[21] The difference of vPro Essentials is that it does not support some features: Out-of-band KVM remote control, Wireless Intel® AMT, Fast call for help, Intel® Remote Secure Erase with Intel® SSD Pro.[22] Intel processors that support vPro Essentials are using Intel Standard Manageability (a subset of Intel AMT)[23] which supports out-of-band management and can be monitored with the "Access Monitor" feature.[24][25]
Intel AMT is the set of management and security features built into vPro PCs that makes it easier for a sys-admin to monitor, maintain, secure, and service PCs.[11] Intel AMT (the management technology) is sometimes mistaken for being the same as Intel vPro (the PC "platform"), because AMT is one of the most visible technologies of an Intel vPro-based PC.
Intel AMT includes:
Hardware-based management has been available in the past, but it has been limited to auto-configuration (of computers that request it) using DHCP or BOOTP for dynamic IP address allocation and disk-less workstations, as well as wake-on-LAN for remotely powering on systems.[26]
Starting with vPro with AMT 6.0, PCs with i5 or i7 processors and embedded Intel graphics, now contains an Intel proprietary embedded VNC server. You can connect out-of-band using dedicated VNC-compatible viewer technology, and have full KVM (keyboard, video, mouse) capability throughout the power cycle—including uninterrupted control of the desktop when an operating system loads. Clients such as VNC Viewer Plus from RealVNC also provide additional functionality that might make it easier to perform (and watch) certain Intel AMT operations, such as powering the computer off and on, configuring the BIOS, and mounting a remote image (IDER).
Not all i5 & i7 Processors with vPro may support KVM capability. This depends on the OEM's BIOS settings as well as if a discrete graphics card is present. Only Intel integrated HD graphics support KVM ability.[27][better source needed]
Intel vPro supports encrypted wired and wireless LAN wireless communication for all remote management features for PCs inside the corporate firewall.[11] Intel vPro supports encrypted communication for some remote management features for wired and wireless LAN PCs outside the corporate firewall.[11][28]
Laptops with vPro include a gigabit network connection and support IEEE 802.11 a/g/n wireless protocols.[11][28][29]
Intel vPro PCs support wireless communication to the AMT features.[11][29]
For wireless laptops on battery power, communication with AMT features can occur when the system is awake and connected to the corporate network. This communication is available if the OS is down or management agents are missing.[11][28]
AMT out-of-band communication and some AMT features are available for wireless or wired laptops connected to the corporate network over a host OS-based virtual private network (VPN) when laptops are awake and working properly.[11]
A wireless connection operates at two levels: the wireless network interface (WLAN) and the interface driver executing on the platform host. The network interface manages the RF communications connection.
If the user turns off the wireless transmitter/receiver using either a hardware or software switch, Intel AMT cannot use the wireless interface under any conditions until the user turns on the wireless transmitter/receiver.
Intel AMT Release 2.5/2.6 can send and receive management traffic via the WLAN only when the platform is in the S0 power state (the computer is on and running). It does not receive wireless traffic when the host is asleep or off. If the power state permits it, Intel AMT Release 2.5/2.6 can continue to send and receive out-of-band traffic when the platform is in an Sx state, but only via a wired LAN connection, if one exists.
Release 4.0 and later releases support wireless out-of-band manageability in Sx states, depending on the power setting and other configuration parameters.
Release 7.0 supports wireless manageability on desktop platforms.
When a wireless connection is established on a host platform, it is based on a wireless profile that sets up names, passwords and other security elements used to authenticate the platform to the wireless Access Point. The user or the IT organization defines one or more profiles using a tool such as Intel PROSet/Wireless Software. In release 2.5/6, Intel AMT must have a corresponding wireless profile to receive out-of-band traffic over the same wireless link. The network interface API allows defining one or more wireless profiles using the same parameters as the Intel PROSet/Wireless Software. See Wireless Profile Parameters. On power-up of the host, Intel AMT communicates with the wireless LAN driver on the host. When the driver and Intel AMT find matching profiles, the driver routes traffic addressed to the Intel AMT device for manageability processing. With certain limitations, Intel AMT Release 4.0/1 can send and receive out-of-band traffic without an Intel AMT configured wireless profile, as long as the host driver is active and the platform is inside the enterprise.
In release 4.2, and on release 6.0 wireless platforms, the WLAN is enabled by default both before and after configuration. That means that it is possible to configure Intel AMT over the WLAN, as long as the host WLAN driver has an active connection. Intel AMT synchronizes to the active host profile. It assumes that a configuration server configures a wireless profile that Intel AMT uses in power states other than S0.
When there is a problem with the wireless driver and the host is still powered up (in an S0 power state only), Intel AMT can continue to receive out-of-band manageability traffic directly from the wireless network interface.
For Intel AMT to work with a wireless LAN, it must share IP addresses with the host. This requires the presence of a DHCP server to allocate IP addresses and Intel AMT must be configured to use DHCP.
Intel vPro PCs support encrypted communication while roaming.[11][29][30]
vPro PCs version 4.0 or higher support security for mobile communications by establishing a secure tunnel for encrypted AMT communication with the managed service provider when roaming (operating on an open, wired LAN outside the corporate firewall).[11] Secure communication with AMT can be established if the laptop is powered down or the OS is disabled.[11] The AMT encrypted communication tunnel is designed to allow sys-admins to access a laptop or desktop PC at satellite offices where there is no on-site proxy server or management server appliance.
Secure communications outside the corporate firewall depend on adding a new element—a management presence server (Intel calls this a "vPro-enabled gateway")—to the network infrastructure.[11] This requires integration with network switch manufacturers, firewall vendors, and vendors who design management consoles to create infrastructure that supports encrypted roaming communication. So although encrypted roaming communication is enabled as a feature in vPro PCs version 4.0 and higher, the feature will not be fully usable until the infrastructure is in place and functional.
vPro security technologies and methodologies are designed into the PC's chipset and other system hardware. During deployment of vPro PCs, security credentials, keys, and other critical information are stored in protected memory (not on the hard disk drive), and erased when no longer needed.
According to Intel, it is possible to disable AMT through the BIOS settings, however, there is apparently no way for most users to detect outside access to their PC via the vPro hardware-based technology.[31] Moreover, Sandy Bridge and future chips will have, "...the ability to remotely kill and restore a lost or stolen PC via 3G ... if that laptop has a 3G connection"[32]
On May 1, [2017] Intel published a security advisory regarding a firmware vulnerability in certain systems that utilize Intel Active Management Technology (Intel AMT), Intel Standard Manageability (Intel ISM), or Intel Small Business Technology (Intel SBT). The vulnerability is potentially very serious, and could enable a network attacker to remotely gain access to businesses PCs and workstations that use these technologies. We urge people and companies using business PCs and devices that incorporate Intel AMT, Intel ISM or Intel SBT to apply a firmware update from your equipment manufacturer when available, or to follow the steps detailed in the mitigation guide.[33][34]
Many vPro features, including AMT, are implemented in the Intel Management Engine (ME), a distinct processor in the chipset running MINIX 3, which has been found to have numerous security vulnerabilities. Unlike for AMT, there is generally no official, documented way to disable the Management Engine (ME); it is always on unless it is not enabled at all by the OEM.[35][36]
Intel vPro supports industry-standard methodologies and protocols, as well as other vendors' security features:[6][11][13][37]
Intel Boot Guard is a processor feature that prevents the computer from running firmware (UEFI) images not released by the system manufacturer (OEM or ODM). When turned on, the processor verifies a digital signature contained in the firmware image before executing it, using the public key of the keypair, the OEM/ODM public key is fused into the system's Platform Controller Hub (PCH)[lower-alpha 1] by the system manufacturer (not by Intel). As a result, Intel Boot Guard, when activated, makes it impossible for end users to install replacement firmware (such as Coreboot) or modded BIOS.[40][41]
Intel Boot Guard was first released in Haswell processors in June 2013.
Intel vPro uses several industry-standard security technologies and methodologies to secure the remote vPro communication channel. These technologies and methodologies also improve security for accessing the PC's critical system data, BIOS settings, Intel AMT management features, and other sensitive features or data; and protect security credentials and other critical information during deployment (setup and configuration of Intel AMT) and vPro use.[11][42]

The first release of Intel vPro was built with an Intel Core 2 Duo processor.[6] The current versions of Intel vPro are built into systems with 10 nm Intel 10th Generation Core i5 & i7 processors.
PCs with Intel vPro require specific chipsets. Intel vPro releases are usually identified by their AMT version.[6][11]
Laptops with Intel vPro require:
Note that AMT release 2.5 for wired/wireless laptops and AMT release 3.0 for desktop PCs are concurrent releases.
Desktop PCs with vPro (called "Intel Core 2 with vPro technology") require:
Note that AMT release 2.5 for wired/wireless laptops and AMT release 3.0 for desktop PCs are concurrent releases.
There are numerous Intel brands. However, the key differences between vPro (an umbrella marketing term), AMT (a technology under the vPro brand), Intel Core i5 and Intel Core i7 (a branding of a package of technologies), and Core i5 and Core i7 (a processor) are as follows:
The Core i7, the first model of the i series was launched in 2008, and the less-powerful i5 and i3 models were introduced in 2009 and 2010, respectively. The microarchitecture of the Core i series was code-named Nehalem, and the second generation of the line was code-named Sandy Bridge.
Intel Centrino 2 was a branding of a package of technologies that included Wi-Fi and, originally, the Intel Core 2 Duo.[5] The Intel Centrino 2 brand was applied to mobile PCs, such as laptops and other small devices. Core 2 and Centrino 2 have evolved to use Intel's latest 45-nm manufacturing processes, have multi-core processing, and are designed for multithreading.
Intel vPro is a brand name for a set of Intel technology features that can be built into the hardware of the laptop or desktop PC.[11] The set of technologies are targeted at businesses, not consumers. A PC with the vPro brand often includes Intel AMT, Intel Virtualization Technology (Intel VT), Intel Trusted Execution Technology (Intel TXT), a gigabit network connection, and so on. There may be a PC with a Core 2 processor, without vPro features built in. However, vPro features require a PC with at least a Core 2 processor. The technologies of current versions of vPro are built into PCs with some versions of Core 2 Duo or Core 2 Quad processors (45 nm), and more recently with some versions of Core i5 and Core i7 processors.
Intel AMT is part of the Intel Management Engine that is built into PCs with the Intel vPro brand. Intel AMT is a set of remote management and security hardware features that let a sys-admin with AMT security privileges access system information and perform specific remote operations on the PC.[6] These operations include remote power up/down (via wake-on-LAN), remote / redirected boot (via integrated device electronics redirect, or IDE-R), console redirection (via serial over LAN), and other remote management and security features.
