Firewalls

Surf the safe way

The Internet connects hundreds of millions of devices to each other, which means any one of those devices can find and access your device. To make sure only the users you approve can access your data and information through the web, you need a firewall.

The same way your anti-virus protection scrutinizes files, emails and downloads between your machine and the web, a firewall acts as a guard between your device and any other device that is trying to access it through the web. It also makes sure all of the access points in your computer are secured at all times except for those few which you are currently using. When you're browsing the Internet, the easiest thing to do is make sure your firewall is "on".

How to enable firewall security:

  • Often, firewall protection will already be part of the OS (operating system) your computer came with. Check to see that it is turned "on", and ensure that it's updated on a constant basis. Your OS' help menu or online help should be able to guide you.
  • If your OS doesn't include a firewall, install your own firewall software, which will always be quietly guarding your device while you go about your surfing.
  • There is a good selection of free and paid firewall software available on the Internet. Look for programs from credible companies.
  • Rather than software, you may also use a hardware firewall, which is an external device with built-in firewall software. For example, wireless routers targeted at home consumers often have a firewall which can be configured via the administrator web access. This type of firewall helps to prevent unwanted traffic from reaching your computers on the network.
  • Just like your other security programs, to gain maximum protection, you need to keep your firewall constantly updated.
