Lesson overview

By adjusting the settings in the Firewall we can block all unwanted access into our computer. It works as a protective barrier to prevent all unwanted connections in, out, and through our computer.

Our company is under attack. We have intelligence that someone is trying to send a virus into our computer. It's your job to help us protect ourselves.

  • First, you'll need to check if we have any ports open which cyber criminals could use to access our information

  • Next, we can help to protect ourselves from unauthorised access by creating a Firewall which acts as a defence barrier

  • Learn how to control what input and output is accessible through the Firewall you have created
