How to Find My Firewall

By Thomas King

A firewall is a piece of software or hardware that sits between a private network and a public network. As the name suggests, a firewall acts as a wall to keep worms, viruses and hackers from accessing your computer. Many operating systems, including Windows and Mac, come with a built-in firewall. A firewall can also be purchased from a third-party software company or even built yourself. Finding your firewall will depend on what type of firewall you have.
