    "A system designed to prevent unauthorized access to or from a private network. Firewalls can be implemented in both hardware and software, or a combination of both. Firewalls are frequently used to prevent unauthorized Internet users from accessing private networks connected to the Internet, especially intranets. All messages entering or leaving the intranet pass through the firewall, which examines each message and blocks those that do not meet the specified security criteria."

    "Software or hardware that limits or restricts certain kinds of computer access from a network or other outside source. A Router is a good example of a hardware device that often has a built-in firewall. Firewalls are used to thwart would-be hackers from infiltrating computer systems."
