How does a firewall work?
A firewall is a network security device that monitors and controls incoming and outgoing network traffic based on predetermined security rules. A firewall typically establishes a barrier between a trusted, internal network and untrusted, external network, such as the Internet.
In an enterprise network, the firewall is often part of a larger security infrastructure that also includes other security devices, such as an intrusion prevention system (IPS), intrusion detection system (IDS), anti-virus software, and so on. The firewall is the first line of defense against network attacks.
Firewalls can be hardware devices, software programs, or a combination of both. Hardware firewalls are typically installed on a network router and protect an entire network. Software firewalls are usually installed on individual computers and only protect the specific computer on which they are installed.
Most modern firewalls use a combination of packet filtering, stateful inspection, and application-level gateways.
Packet filtering is the process of allowing or denying network traffic based on criteria such as source and destination IP address, port number, and protocol type. Stateful inspection is a more sophisticated form of packet filtering that keeps track of the state of each connection and makes sure that packets are only allowed through the firewall if they are part of an established, legitimate connection.
An application-level gateway, also known as a proxy server, is a type of firewall that inspects traffic at the application layer of the OSI model. Proxy servers can provide additional security by filtering out malicious or unwanted content, such as advertising banners or pop-up windows.
Most firewalls use a combination of all three methods to provide the best possible protection.
