What is a Firewall?

When your computer is accessible through an internet connection or Wi-Fi network, it is susceptible to attack. However, you can restrict outside access to your computer—and the information on it—with a firewall.

At its core, a firewall is essentially the barrier that sits between a private internal network and the public Internet.

Firewalls provide protection against outside cyber attackers by shielding your computer or network from malicious or unnecessary network traffic. Firewalls can also prevent malicious software from accessing a computer or network via the internet. Firewalls can be configured to block data from certain locations (i.e., computer network addresses), applications, or ports while allowing relevant and necessary data through.
