What is a firewall?

Use a firewall to secure your Internet connection

You should protect your Internet connection with a firewall.
This effectively creates a ‘buffer zone’ between your IT network and other, external networks.

In the simplest case, this means between your computer (or computers) and ‘the Internet’. Within this buffer zone, incoming traffic can be analysed to find out whether or not it should be allowed onto your network.

Two types of firewall
You could use a personal firewall on your internet connected laptop (normally included within your Operating System at no extra charge).

Or, if you have a more complicated set up with many different types of devices, you might require a dedicated boundary firewall, which places a protective buffer around your network as a whole.

Some routers will contain a firewall which could be used in this boundary protection role. But, this can’t be guaranteed – if you can, ask your internet service provider about your specific model.
