AQA Computer Science GCSE
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.
Part 1 – What is Cyber Security?
Cyber Security Definitions and Purposes
Part 2 – Cyber Security Threats
There are seven classic cyber security threats that you need to understand about.
Threats 1 (social engineering) and 2 (malware) are things we need to go into detail on, so leave these for now.
Cyber Security Threats – slides from class
Cyber Security Textbook Spread – notes with more details and activities
Part 3 – Penetration Testing
Penetration Testing – summary slides
This is also covered in the textbook Spread above.
Note that on old exams (pre-2024), the exam board used the terms "white box" and "black box" testing. They don't use those anymore, but you might still see them in old resources or on old exam questions. The new versions of each term are "malicious insider" and "external attack".
