Firewalls

It is essential that any computer connected to the internet is protected by a firewall to ensure the security of your financial transactions and computer. A firewall helps protect your computer from hackers who may try to steal or delete information from your computer.

If you are using a combined modem/router, or any type of internet or broadband router you should review the documentation that came with the device and familiarise yourself with the configuration page. Usually the configuration page can be easily accessed by typing the device's IP address available from their documentation, into your web browser's address bar.

Many of these devices have a built-in firewall which is often disabled by default. By enabling the built-in firewall, you will be better protected against manual and automated attacks on your computer system.

You should also consider installing personal firewall software on your computer. Microsoft Windows XP (Service Pack 2 and 3) and Microsoft Windows Vista provide the built-in Windows Firewall, which is enabled by default, but more detailed configuration and functionality can be provided by other third party products.

Some of the leading commercial names in firewall software are listed on the Security software page. If you choose free security applications we recommend you seek guidance from an IT professional to ensure you are choosing reputable applications.
