Firewalls and Antivirus Software

Start with the main ideas

The mind map Firewall is a starting point for looking at traffic between a computer and the internet. Follow it with Anti-virus software, which describes ways antivirus software protects a computer and its files.

As you study each map, note the different roles of a firewall and antivirus software. Then try explaining each role in your own words before returning to the maps to check your understanding.

Explore protection in more detail

Data levels and protection brings firewalls and antivirus software together. It describes firewalls as hardware or software and outlines how rules filter suspicious network packets. The Data Protection mind maps also cover firewall rules and network packets.

For another view of antivirus protection, open Anti-malware software. Its excerpt describes scanning files that a user opens or downloads. Compare that idea with what you found in the antivirus map.

Check what you know

The chapter quiz includes questions about antivirus protection and antivirus software. Try it after looking at the maps, then return to the relevant material when you want to check an idea. The definitions flashcards also include antivirus and firewall terms, making them useful for practicing vocabulary alongside the maps.

Connect ideas across the unit

This topic is part of a wider unit in Computing and ICT. The resources on data protection bring firewall and antivirus ideas together, while the definitions flashcards place them alongside other computer science terms. Use those resources to see the terms in context rather than studying each one in isolation.
