Firewall (computing)
In computing, a firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. A firewall typically establishes a barrier between a trusted network and an untrusted network, such as the Internet. History The term '' firewall'' originally referred to a wall intended to confine a fire within a line of adjacent buildings. Later uses refer to similar structures, such as the metal sheet separating the engine compartment of a vehicle or aircraft from the passenger compartment. The term was applied in the late 1980s to network technology that emerged when the Internet was fairly new in terms of its global use and connectivity. The predecessors to firewalls for network security were routers used in the late 1980s. Because they already segregated networks, routers could apply filtering to packets crossing them. Before it was used in real-life computing, the term appeared in the 1983 computer-hacking movi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Personal Firewall
A personal firewall is an application which controls network traffic to and from a computer, permitting or denying communications based on a security policy. Typically it works as an application layer firewall. A personal firewall differs from a conventional firewall in terms of scale. A personal firewall will usually protect only the computer on which it is installed, as compared to a conventional firewall which is normally installed on a designated interface between two or more networks, such as a router or proxy server. Hence, personal firewalls allow a security policy to be defined for individual computers, whereas a conventional firewall controls the policy between the networks that it connects. The per-computer scope of personal firewalls is useful to protect machines that are moved across different networks. For example, a laptop computer may be used on a trusted intranet at a workplace where minimal protection is needed as a conventional firewall is already in place, a ...

Chinese Wall
A Chinese wall or ethical wall is an information barrier protocol within an organization designed to prevent exchange of information or communication that could lead to conflicts of interest. For example, a Chinese wall may be established to separate people who make investments from those who are privy to confidential information that could improperly influence the investment decisions. Firms are generally required by law to safeguard insider information and ensure that improper trading does not occur. Etymology Bryan Garner's ''Dictionary of Modern Legal Usage'' states that the metaphor title "derives ''of course'' from the Great Wall of China",, italics added although an alternative explanation links the idea to the screen walls of Chinese internal architecture. The term was popularized in the United States following the stock market crash of 1929, when the U.S. government legislated information separation between investment bankers and brokerage firms, in order to limit ...

Great Firewall
The Great Firewall (''GFW''; ) is the combination of legislative actions and technologies enforced by the People's Republic of China to regulate the Internet domestically. Its role in internet censorship in China is to block access to selected foreign websites and to slow down cross-border internet traffic. The Great Firewall operates by checking transmission control protocol (TCP) packets for keywords or sensitive words. If the keywords or sensitive words appear in the TCP packets, access will be closed. If one link is closed, more links from the same machine will be blocked by the Great Firewall. The effect includes: limiting access to foreign information sources, blocking foreign internet tools (e.g. Google Search, Facebook, Twitter, Wikipedia, and others) and mobile apps, and requiring foreign companies to adapt to domestic regulations. Besides censorship, the Great Firewall has also influenced the development of China's internal internet economy by giving preference to domesti ...

Firewalld
firewalld is a firewall management tool for Linux operating systems. It provides firewall features by acting as a front-end for the Linux kernel's netfilter framework. firewalld's current default backend is nftables. Prior to v0.6.0, iptables was the default backend. Through its abstractions, firewalld acts as an alternative to nft and iptables command line programs. The name ''firewalld'' adheres to the Unix convention of naming system daemons by appending the letter "d". firewalld is written in Python. It was intended to be ported to C++, but the porting project was abandoned in January 2015. Features firewalld supports both IPv4 and IPv6 networks and can administer separate ''firewall zones'' with varying degrees of trust as defined in ''zone profiles''. Administrators can configure Network Manager to automatically switch zone profiles based on known Wi-Fi (wireless) and Ethernet (wired) networks, but firewalld cannot do this on its own. Services and applications can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alberta Agenda
The Alberta Agenda, the Firewall Letter, was a January 2001 open letter by seven prominent conservatives in Alberta—including Calgary School professors and Stephen Harper—addressed to then Premier of Alberta, Ralph Klein, setting out a five-point firewall to "protect Alberta" from the alleged "intrusions" by the federal government. the Alberta government to fully exercise the province's constitutional powers. The group, who called themselves the Alberta Residents League (ARL) proposed the Alberta Agenda—a "new vision" for the province, which focused on "More Alberta, less Ottawa". The letter was composed by Harper—then president of the National Citizens Coalition. Harper later served as Canada's Prime Minister for three consecutive terms—from 2006 to 2015. Signatories included three political science professors associated with the "Calgary School" as the University of Calgary— Tom Flanagan, Ted Morton, and Rainer Knopff. Other signatories included Andrew Crooks, who was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ReBoot
In computing, rebooting is the process by which a running computer system is restarted, either intentionally or unintentionally. Reboots can be either a cold reboot (alternatively known as a hard reboot) in which the power to the system is physically turned off and back on again (causing an initial boot of the machine); or a warm reboot (or soft reboot) in which the system restarts while still powered up. The term restart (as a system command) is used to refer to a reboot when the operating system closes all programs and finalizes all pending input and output operations before initiating a soft reboot. Terminology Etymology Early electronic computers (like the IBM 1401) had no operating system and little internal memory. The input was often a stack of punch cards or via a Switch Register. On systems with cards, the computer was initiated by pressing a start button that performed a single command - "read a card". This first card then instructed the machine to read more card ...

Firewall (construction)
A firewall is a fire-resistant barrier used to prevent the spread of fire. Firewalls are built between or through buildings, structures, or electrical substation transformers, or within an aircraft or vehicle. Applications Firewalls can be used to subdivide a building into separate fire areas and are constructed in accordance with the locally applicable building codes. Firewalls are a portion of a building's passive fire protection systems. Firewalls can be used to separate-high value transformers at an electrical substation in the event of a mineral oil tank rupture and ignition. The firewall serves as a fire containment wall between one oil-filled transformer and other neighboring transformers, building structures, and site equipment. Types There are three main classifications of ''fire rated walls'': fire walls, fire barriers, and fire partitions. *A ''firewall'' is an assembly of materials used to separate transformers, structures, or large buildings to prevent the sp ...
