Intel AMT Versions
Intel Active Management Technology (AMT) is hardware-based technology built into PCs with Intel vPro technology. AMT is designed to help sys-admins remotely manage and secure PCs out-of-band when PC power is off, the operating system (OS) is unavailable (hung, crashed, corrupted, missing), software management agents are missing, or hardware (such as a hard disk drive or memory) has failed. Versions Intel AMT is built into a small secondary processor located on the motherboard. This OOB controller has embedded firmware that runs on the Manageability Engine (ME), a separate small processor built into the northbridge (or network card for AMT 1.0) of the motherboard. The AMT firmware is stored in the same SPI flash memory component used to store the BIOS and is generally updated along with the BIOS. FWH (Firmware Hub) or LPC firmware storage is not supported for AMT. In general, an AMT version can be updated in software to the next minor version. New major releases of Intel AMT are ...

Intel Active Management Technology
Intel Active Management Technology (AMT) is hardware and firmware for remote out-of-band management of select business computers, running on the Intel Management Engine, a microprocessor subsystem not exposed to the user, intended for monitoring, maintenance, updating, and repairing systems. Out-of-band (OOB) or hardware-based management is different from software-based (or in-band) management and software management agents. Hardware-based management works at a different level from software applications, and uses a communication channel (through the TCP/IP stack) that is different from software-based communication (which is through the software stack in the operating system). Hardware-based management does not depend on the presence of an OS or a locally installed management agent. Hardware-based management has been available on Intel/AMD based computers in the past, but it has largely been limited to auto-configuration using DHCP or BOOTP for dynamic IP address allocation and ...

Host Embedded Controller Interface
Host Embedded Controller Interface (HECI) is technology introduced in 2006 used for Active Management Technology (AMT) in Intel chipsets that support Core 2 Duo microprocessors. Details The HECI bus allows the host operating system (OS) to communicate directly with the Management Engine (ME) integrated in the chipset. This bi-directional, variable data-rate bus enables the host and ME to communicate system management information and events in a standards-compliant way, essentially replacing the System Management Bus (SMBus). The bus consists of four wires: a request and grant pair along with a serial transmit and receive data pair. Original equipment manufacturers (OEMs) have historically provided active management technologies through the use of proprietary on-board controllers, such as Baseboard Management Controllers. These solutions typically suffer two main disadvantages due to their proprietary nature. High BOM costs are usually incurred due to the need for addition ...

IPv6
Internet Protocol version 6 (IPv6) is the most recent version of the Internet Protocol (IP), the communication protocol, communications protocol that provides an identification and location system for computers on networks and routes traffic across the Internet. IPv6 was developed by the Internet Engineering Task Force (IETF) to deal with the long-anticipated problem of IPv4 address exhaustion, and is intended to replace IPv4. In December 1998, IPv6 became a Draft Standard for the IETF, which subsequently ratified it as an Internet Standard on 14 July 2017. Devices on the Internet are assigned a unique IP address for identification and location definition. With the rapid growth of the Internet after commercialization in the 1990s, it became evident that far more addresses would be needed to connect devices than the IPv4 address space had available. By 1998, the IETF had formalized the successor protocol. IPv6 uses 128-bit addresses, theoretically allowing 2128, or approximatel ...

KVM Switch
A KVM switch (with KVM being an abbreviation for "keyboard, video, and mouse") is a hardware device that allows a user to control multiple computers from one or more sets of keyboards, video monitors, and mice. Name Switches to connect multiple computers to one or more peripherals have had a variety of names. The earliest name was Keyboard Video Switch (KVS). With the advent of the mouse, the Keyboard, Video and Mouse (KVM) switch became popular. The name was introduced by Remigius Shatas, the founder of Cybex, a peripheral switch manufacturer, in 1995. Some companies call their switches Keyboard, Video, Mouse and Peripheral (KVMP). Types With the popularity of USB—USB keyboards, mice, and I/O devices are still the most common devices connected to a KVM switch. The classes of KVM switches that are reviewed, are based on different types of core technologies in terms of how the KVM switch handles USB I/O devices—including keyboards, mice, touchscreen displays, etc. ...

Network Access Protection
Network Access Protection (NAP) is a Microsoft technology for controlling network access of a computer, based on its health. With NAP, system administrators of an organization can define policies for system health requirements. Examples of system health requirements are whether the computer has the most recent operating system updates installed, whether the computer has the latest version of the anti-virus software signature, or whether the computer has a host-based firewall installed and enabled. Computers with a NAP client will have their health status evaluated upon establishing a network connection. NAP can restrict or deny network access to the computers that are not in compliance with the defined health requirements. NAP was deprecated in Windows Server 2012 R2 and removed from Windows Server 2016. Overview Network Access Protection Client Agent makes it possible for clients that support NAP to evaluate software updates for their statement of health. NAP clients are compute ...

Client Initiated Remote Access
Intel CIRA enables out-of-band management systems, such as Intel AMT. It is intended to enable centralized corporate management and administration of laptops that are not attached to the corporate LAN, but rather are located off-site (homes, hotels, ''etc''.). Because off-site systems will typically be behind a firewall, there is no way for the corporate administrator to directly find the machine. Thus, instead, the system (the 'client') will initiate a connection to the corporate administration server; the server can then use this connection to admin the machine. The system is implemented in firmware, and is meant to enable administration resources such as Intel AMT and Intel vPro. See also * Intel vPro 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).

WS-Management
WS-Management (Web Services-Management) is a DMTF open standard defining a SOAP-based protocol for the management of servers, devices, applications and various Web services. WS-Management provides a common way for systems to access and exchange management information across the IT infrastructure. Design The specification is based on DMTF open standards and Internet standards for Web services. The specification is quite rich, supporting much more than get/set of simple variables, and in that it is closer to WBEM or Netconf than to SNMP. A mapping of the DMTF-originated Common Information Model into WS-Management was also defined. History WS-Management was originally developed by a coalition of vendors. The coalition started with AMD, Dell, Intel, Microsoft, Sun Microsystems and expanded to a total of 13 members before being subsumed by the DMTF in 2005. The DMTF has published the standards document DSP0226 with version 1.2 of September 30, 2014. Implementations and appli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TLS-PSK
Transport Layer Security pre-shared key ciphersuites (TLS-PSK) is a set of cryptographic protocols that provide secure communication based on pre-shared keys (PSKs). These pre-shared keys are symmetric keys shared in advance among the communicating parties. There are several cipher suites: The first set of ciphersuites use only symmetric key operations for authentication. The second set use a Diffie–Hellman key exchange authenticated with a pre-shared key. The third set combine public key authentication of the server with pre-shared key authentication of the client. Usually, Transport Layer Security (TLS) uses public key certificates or Kerberos for authentication. TLS-PSK uses symmetric keys, shared in advance among the communicating parties, to establish a TLS connection. There are several reasons to use PSKs: * Using pre-shared keys can, depending on the ciphersuite, avoid the need for public key operations. This is useful if TLS is used in performance-constrained envir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kerberos (protocol)
Kerberos () is a computer-network authentication protocol that works on the basis of ''tickets'' to allow nodes communicating over a non-secure network to prove their identity to one another in a secure manner. Its designers aimed it primarily at a client–server model, and it provides mutual authentication—both the user and the server verify each other's identity. Kerberos protocol messages are protected against eavesdropping and replay attacks. Kerberos builds on symmetric-key cryptography and requires a trusted third party, and optionally may use public-key cryptography during certain phases of authentication.RFC 4556, abstract. Kerberos uses UDP port 88 by default. The protocol was named after the character '' Kerberos'' (or ''Cerberus'') from Greek mythology, the ferocious three-headed guard dog of Hades. History and development Massachusetts Institute of Technology (MIT) developed Kerberos in 1988 to protect network services provided by Project Athena. The protocol is ...

SOAP
Soap is a salt of a fatty acid used in a variety of cleansing and lubricating products. In a domestic setting, soaps are surfactants usually used for washing, bathing, and other types of housekeeping. In industrial settings, soaps are used as thickeners, components of some lubricants, and precursors to catalysts. When used for cleaning, soap solubilizes particles and grime, which can then be separated from the article being cleaned. In hand washing, as a surfactant, when lathered with a little water, soap kills microorganisms by disorganizing their membrane lipid bilayer and denaturing their proteins. It also emulsifies oils, enabling them to be carried away by running water. Soap is created by mixing fats and oils with a base. A similar process is used for making detergent which is also created by combining chemical compounds in a mixer. Humans have used soap for millennia. Evidence exists for the production of soap-like materials in ancient Babylon around 2800 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
