Answer:
A firewall is a system designed to prevent unauthorized access to or from a private network. Firewalls prevent unauthorized internet users from accessing private networks connected to the internet, especially intranets.
Generally the firewall has two network interfaces: one for the external side of the network, one for the internal side. Its purpose is to control what traffic is allowed to traverse from one side to the other. As the most basic level, firewalls can block traffic intended for particular IP addresses or server ports.
