In computing, a firewall is a network security system that monitors and controls the incoming and outgoing network traffic based on predetermined security rules. A firewall typically establishes a barrier between a trusted, secure internal network and another outside network, such as the Internet, that is assumed to not be secure or trusted. Firewalls are often categorized as either network firewalls or host-based firewalls. Network firewalls are a software appliance running on general purpose hardware or hardware-based firewall computer appliances that filter traffic between two or more networks. Host-based firewalls provide a layer of software on one host that controls network traffic in and out of that single machine. Firewall appliances may also offer other functionality to the internal network they protect such as acting as a DHCP or VPN server for that network.
History
The term firewall originally referred to a wall intended to confine a fire or potential fire within a building. 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 Nick Stone Missions are a series of action thriller novels written by author Andy McNab, based on his own experiences in the SAS. The first book in the series, Remote Control was published in February 1998 by Transworld Publishers under their Corgi imprint.

Stone now works as a paid mercenary, willing to work in even the most difficult circumstances. The series has Stone dealing with assassination, political intrigue, as well as human rights, white slavery, and prostitution.
A firewall is a fire resistant barrier used to prevent the spread of fire for a prescribed period of time. Firewalls are built between or through buildings, structures, 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. To the layperson, the common use of language typically includes all three when referring to a firewall unless distinguishing between them becomes necessary. In addition specialty fire rated walls such as a High Challenge Fire Wall would require further distinctions.
