This page is up to date for the AQA 8525 syllabus for exams from 2022.

Cyber Security

Cyber security is a major issue. It's all about how we protect computer systems and our data from attack and damage.

In a modern world that's increasingly dependent on computer systems and the data they store and process, it's vital that we're able to use those systems whenever we need to. But there are all sorts of reasons why they might be under attack and ways we might lose control of our data.

Note that there are strong links in this unit to Network Security and the Unit 8 - Ethics: hacking and cracking section. These parts of Unit 8 could well be the focus for longer questions on Paper 2.
