Firewall is a security tool that helps protect computer networks from unauthorized access and intrusion. A firewall can be a stand-alone device or it can be incorporated into an operating system or an application. There are three types of firewall: network, application, and host. Network firewalls protect computer networks by controlling the flow of traffic between computers.

Application firewalls protect applications by controlling the flow of traffic between applications. Host firewalls protect individual hosts by controlling the flow of traffic between hosts. .

Network firewalls are the most common type of firewall.

Network firewalls use filters to control the traffic that passes through them. Filters can be configured to allow or deny traffic based on its source, destination, or type.
