What is a firewall?

A firewall is considered a first line of defence in protecting private information.

Why do I need one?

If your computer is not protected when you connect to the Internet, hackers can gain access to personal information on your computer. They can install code on your computer that destroys files or causes malfunctions. They can also use your computer to cause problems on other home and business computers connected to the Internet. A firewall helps to screen out many kinds of malicious Internet traffic before it reaches your system.

Some firewalls can also help to prevent other people from using your computer to attack other computers without your knowledge. Using a firewall is important no matter how you connect to the Internet — dial-up modem, digital subscriber line (ADSL/SDSL) and leased line (the latter two are of special importance due to their "always on" nature).

If you are still unsure how firewall will help keep your business secure, or would like to discuss the best way of implementing a firewall on your network, contact domain8 now.
