A firewall is a security system designed to prevent unauthorized access into or out of a computer network. Firewalls are often used to make sure internet users without access are not able to interface with private networks, or intranets, connected to the internet.
A firewall is positioned between a network or a computer and a different network, like the internet. It controls the network traffic coming in and going out of the computer or network.
