A firewall is a security system designed to prevent unauthorized access into or out of a computer network. Firewalls are often used to make sure internet users without access are not able to interface with private networks, or intranets, connected to the internet.
A firewall is positioned between a network or a computer and a different network, like the internet. It controls the network traffic coming in and going out of the computer or network. If you do not have a firewall, virtually any data can exit your computer or network, and virtually any individual or program can come in.
Basically, a firewall is a cybersecurity solution that protects your computer or network from unwanted traffic coming in or going out. It inspects and authenticates all data packets in network traffic before they are allowed to move to a more secure environment.
Whether a hardware appliance or a software program that is protecting a corporate network or a personal computer, a firewall is essential to network security. For example, depending on where a firewall is installed, it may guard against insider threats in a network segment or act as a barrier against external threats at the network perimeter.
As your organization’s first line of defense, a firewall monitors and filters all network traffic including outgoing traffic, application-layer traffic, online transactions, communications, and connectivity. It blocks incoming threats based on a set of pre-programmed rules that also may dictate which users can access specific network areas.
It protects your network from unauthorized access to mitigate the risk from cyber attacks.
