Setting Up Firewalls

A firewall is a protective piece of software that runs on your system and helps to prevent unauthorized access to you computer. Hackers love computers without firewalls, because they are free to probe the computer, looking for weaknesses and vulnerabilities to exploit. A firewall will only allow your computer to communicate with other computers that you already have initiated a conversation with. Unsolicited attempts by hackers to connect are immediately blocked before anything can learned about your system. Both Windows and Mac systems have built-in firewalls that you can easily enable. Also, many software vendors sell effective firewall products that often have more features than the preinstalled versions on personal computers. But since all Windows and Mac computers come with the built-in firewalls, we will look at how to enable and configure those.

For instructions on how to configure the firewall for your Operating System please follow the links below.
