What is a Firewall? Annabel L & Jasmine M

As part of our Expert’s Challenge, in which pupils teach their peers about a chosen E-Threat, Annabel and Jasmine decided to create their own webpage on Firewalls using HTML coding.


What is a firewall?

A firewall is a software program or piece of hardware that helps keep out hackers, viruses, and worms, a programme that can access your files and other programmes, that try to reach your computer over the Internet.(2, 3)

What happens if you don’t have firewall?

If you get a computer and leave it without firewall it will be attacked within minuets. You could be attacked through open ports, and bombarded with popup messages.(4)
