Cyber Security

Cyber security is the protection of computer systems, networks and data from threats such as theft, damage and unauthorised access.

A threat is anything that tries to steal, alter, damage or block access to data, or to gain control of a system without permission. This topic has two halves: the threats an attacker can use, and the solutions that keep data safe from them. For every threat the exam expects you to describe what it is, how it works and what the attacker aims to achieve; for every solution it expects what it does and how it protects the data.
