Firewall (computing)

In computing , a firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. The term firewall originally referred to a wall intended to confine a fire within a line of adjacent buildings. The term was applied in the late s to network technology [4] that emerged when the Internet was fairly new in terms of its global use and connectivity. Because they already segregated networks, routers could apply filtering to packets crossing them. Before it was used in real-life computing, the term appeared in the computer-hacking movie WarGames , and possibly inspired its later use. Firewalls are categorized as a network-based or a host-based system.

Network security is a broad term that covers a multitude of technologies, devices and processes. In its simplest term, it is a set of rules and configurations designed to protect the integrity, confidentiality and accessibility of computer networks and data using both software and hardware technologies.

One of the major challenges that companies face when trying to secure their sensitive data is finding the right tools for the job. Even for a common tool such as a firewall sometimes called a network firewall , many businesses might not have a clear idea of how to find the right firewall or firewalls for their needs, how to configure those firewalls, or why such firewalls might be necessary. A firewall is a type of cybersecurity tool that is used to filter traffic on a network. Firewalls can be used to separate network nodes from external traffic sources, internal traffic sources, or even specific applications. Firewalls can be software, hardware, or cloud-based, with each type of firewall having its own unique pros and cons. The primary goal of a firewall is to block malicious traffic requests and data packets while allowing legitimate traffic through.
