A firewall is a system designed to prevent unauthorised access to private computer network. Firewalls are normally used to prevent unauthorised Internet users from accessing private networks connected to the Internet (often described as intranets).
Firewalls are frequently categorised as either network firewalls or host-based firewalls. Network firewalls filter traffic between two or more networks and running on network hardware. Host based run on crowd computers and control network traffic in and out of those machines. You can implement the firewall in either hardware or software form or a combination of both. Firewalls check unauthorized internet users from accessing private networks connected to the internet, especially intranets.
The term firewall originally referred a wall intended for release a fire within a building. Later users refer to similar structures, such as the metal sheet separating the engine compartment of a vehicle or aircraft from the passenger compartment.

The predecessors to firewalls network security such as were the routers used in the late 1980’s.
Firewalls are generally categorised as network-based or host-based. Network-based firewalls are positioned on the gateway computers of LAN, WAN and intranets. They are either software appliance running on general-purpose hardware, or hardware-based firewall computer appliances. Firewall appliances may also offer other functionality to the internal network they protect, such as acting as a or VPN server for that network. Host-based firewalls are located on the network node itself and control network traffic in and out of those machines.
