Management Interface
In computing, a management interface is a network interface dedicated to configuration and management operations. Management interfaces are typically connected to dedicated out of band management networks (either VPNs or physical networks), and non-management interfaces are not allowed to carry device or network management traffic. This greatly reduces the attack surface of the managed devices, as external attackers cannot access management functions directly, and thus improves network security. In some cases, serial ports are used to access the command line interface directly, avoiding transport over a generic network stack completely, providing a further layer of isolation from network attacks. See also * Management plane In computer networking, the management plane of a networking device is the element of a system that configures, monitors, and provides management, monitoring and configuration services to, all layers of the network stack and other parts of the s ... {{ ...

Computing
Computing is any goal-oriented activity requiring, benefiting from, or creating computer, computing machinery. It includes the study and experimentation of algorithmic processes, and the development of both computer hardware, hardware and software. Computing has scientific, engineering, mathematical, technological, and social aspects. Major computing disciplines include computer engineering, computer science, cybersecurity, data science, information systems, information technology, and software engineering. The term ''computing'' is also synonymous with counting and calculation, calculating. In earlier times, it was used in reference to the action performed by Mechanical computer, mechanical computing machines, and before that, to Computer (occupation), human computers. History The history of computing is longer than the history of computing hardware and includes the history of methods intended for pen and paper (or for chalk and slate) with or without the aid of tables. ...

Network Interface Controller
A network interface controller (NIC, also known as a network interface card, network adapter, LAN adapter and physical network interface) is a computer hardware component that connects a computer to a computer network. Early network interface controllers were commonly implemented on expansion cards that plugged into a computer bus. The low cost and ubiquity of the Ethernet standard means that most newer computers have a network interface built into the motherboard, or is contained into a USB-connected dongle, although network cards remain available. Modern network interface controllers offer advanced features such as interrupt and Direct memory access, DMA interfaces to the host processors, support for multiple receive and transmit queues, partitioning into multiple logical interfaces, and on-controller network traffic processing such as the TCP offload engine. Purpose The network controller implements the electronic circuitry required to communicate using a specific physica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Out-of-band Management
In systems management, out-of-band management (OOB; also lights-out management or LOM) is a process for accessing and managing devices and infrastructure at remote locations through a separate management plane from the production network. OOB allows a system administrator to monitor and manage servers and other network-attached equipment by remote control regardless of whether the machine is powered on or whether an OS is installed or functional. It is contrasted to ''in-band management'' which requires the managed systems to be powered on and available over their operating system's networking facilities. OOB can use dedicated management interfaces, serial ports, or cellular 4G and 5G networks for connectivity. Out-of-band management is now considered an essential network component to ensure business continuity and many manufacturers have it as a product offering. Out-of-band versus in-band By contrast, ''in-band management'' through VNC or SSH is based on in-band connectivit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Attack Surface
The attack surface of a software environment is the sum of the different points (for " attack vectors") where an unauthorized user (the "attacker") can try to enter data to, extract data, control a device or critical software in an environment. Keeping the attack surface as small as possible is a basic security measure. Elements of an attack surface Worldwide digital change has accelerated the size, scope, and composition of an organization's attack surface. The size of an attack surface may fluctuate over time, adding and subtracting assets and digital systems (e.g. websites, hosts, cloud and mobile apps, etc.). Attack surface sizes can change rapidly as well. Digital assets eschew the physical requirements of traditional network devices, servers, data centers, and on-premise networks. This leads to attack surfaces changing rapidly, based on the organization's needs and the availability of digital services to accomplish it. Attack surface scope also varies from organization ...

Serial Port
A serial port is a serial communication Interface (computing), interface through which information transfers in or out sequentially one bit at a time. This is in contrast to a parallel port, which communicates multiple bits simultaneously in Parallel communication, parallel. Throughout most of the history of personal computers, data has been transferred through serial ports to devices such as modems, computer terminal, terminals, various peripherals, and directly between computers. While interfaces such as Ethernet, FireWire, and USB also send data as a serial Stream (computing), stream, the term ''serial port'' usually denotes Computer hardware, hardware compliant with RS-232 or a related standard, such as RS-485 or RS-422. Modern consumer personal computers (PCs) have largely replaced serial ports with higher-speed standards, primarily USB. However, serial ports are still frequently used in applications demanding simple, low-speed interfaces, such as industrial automation sys ...

Command Line Interface
A command-line interface (CLI) is a means of interacting with software via commands each formatted as a line of text. Command-line interfaces emerged in the mid-1960s, on computer terminals, as an interactive and more user-friendly alternative to the non-interactive mode available with punched cards. For a long time, a CLI was the most common interface for software, but today a graphical user interface (GUI) is more common. Nonetheless, many programs such as operating system and software development utilities still provide CLI. A CLI enables automating programs since commands can be stored in a script file that can be used repeatedly. A script allows its contained commands to be executed as group; as a program; as a command. A CLI is made possible by command-line interpreters or command-line processors, which are programs that execute input commands. Alternatives to a CLI include a GUI (including the desktop metaphor such as Windows), text-based menuing (including ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Management Plane
In computer networking, the management plane of a networking device is the element of a system that configures, monitors, and provides management, monitoring and configuration services to, all layers of the network stack and other parts of the system. It should be distinguished from the control plane, which is primarily concerned with routing table In computer networking, a routing table, or routing information base (RIB), is a data table stored in a router or a network host that lists the routes to particular network destinations, and in some cases, metrics (distances) associated wi ... and forwarding information base computation. In system diagrams, the management plane is typically shown in three dimensions as overlapping the network stack, separated by a dimension that delineates the power plane, control plane, data plane, and management plane.
