A firewall is a device that prevents unauthorized access to a host or a network either from within the corporate environment or coming from the public network, like the internet. Generally, there are two types of firewalls. A hardware firewall takes the form of a closed proprietary appliance with its own operating system. This is considered faster but a bit expensive. A software firewall is installed on a computer and it utilizes the computer's operating system. Firewalls either hardware or software use rules to filter incoming and outgoing traffic to the network.
