Cyber Security Career Guide

What cyber security is

Cyber security is the practice of protecting systems, networks, and data from attacks and unauthorised access. It is a defensive, protective field — the goal is to keep people and organisations safe, and all legitimate work in it is done lawfully and with proper authorisation.

Courses and skills that help

Useful foundations include computer networks, operating systems, and programming, on top of which you build security-specific knowledge. People enter from computer-science degrees, dedicated cyber-security programmes, and recognised professional certifications. Practical, hands-on practice in lawful, authorised settings (such as labs and approved exercises) is valuable.
