    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.

    The five types of firewall are:

    Packet filtering firewall
    Circuit-level gateway
    Stateful inspection firewall
    Application-level gateway (aka proxy firewall)
    Next-generation firewall (NGFW)

    Firewalls are one of the oldest network perimeter security tools in the market, and it’s just as important today as it was 30 years ago. Filtering out malicious traffic before it enters a network is a crucial network security operation.

    With technological evolution, firewalls have advanced in capabilities and functions. I’ll list the five broad types of firewalls here without going into too much detail.

    Packet filtering firewalls – Network access is controlled by inspecting outgoing and incoming packets based on source and destinations, such as IP addresses, protocols, and ports. It’s also called a static firewall.

    Stateful inspection firewalls – Also called a dynamic firewall, it inspects packets and checks whether the packet belongs to a particular session or not.

    Proxy firewalls – It's a much more thorough firewall, as it verifies requests at the application level itself. It prevents direct contact between external clients and your internal server.

    Next-generation firewalls (NGFW) - It’s an “intelligent” firewall that combines traditional capabilities with newer technologies like deep packet inspection (DPI) and intrusion prevention systems (IPS).
