A firewall is a system that monitors and controls the incoming and outgoing network traffic based on predetermined security rules.

Firewalls are usually deployed at the perimeter of an organisation’s network. The firewall’s goal is to prevent unauthorized access to or from an organization’s private network.

Firewalls are often categorized into two types: personal firewalls, which are installed on individual computers, and network firewalls, which are installed at the gateway of a corporation’s intranet.
