firewall Computing a computer system that isolates another computer from the internet in order to prevent unauthorized access firewall[′fī‚wȯl] (computer science) Hardware and software programs that protect the resources of a private network from users in other networks, controlling all traffic according to a predefined access policy. firewall A noninflammable partition separating the whole or a portion of an engine nacelle from the rest of the aircraft to prevent the spread of fire. Each separated area is called a fire zone and often has its own fire detectors and extinguishers.

A firewall allows or blocks traffic into and out of a private network or the user's computer. Firewalls are widely used to give users secure access to the Internet as well as to separate a company's public Web server from its internal network. Firewalls are also used to keep internal network segments secure; for example, the accounting network might be vulnerable to snooping from within the enterprise.
In the home, a personal firewall typically comes with or is installed in the user's computer (see Windows Firewall). Personal firewalls may also detect outbound traffic to guard against spyware, which could be sending your surfing habits to a website. They alert you when software makes an outbound request for the first time (see spyware).
In the organization, a firewall can be a stand-alone machine (see firewall appliance) or software in a router or server. It can be as simple as a single router that filters out unwanted packets, or it may comprise a combination of routers and servers each performing some type of firewall processing. For more about the various firewall techniques, see firewall methods.
