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. Routers that pass data between networks contain firewall components and can often perform basic routing functions as well, 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.
