Description
Cyber security is no longer a specialist concern tucked away in a server room. It plays a role in keeping hospitals running, protecting financial systems, supporting the integrity of elections, and safeguarding personal information.
This course provides an accessible introduction to cyber security for anyone who wants to understand the subject without an IT, coding, or networking background.
Across twelve focused five-minute lessons, you'll explore what cyber security means, how the field developed, and the fundamental problems it is designed to address. You'll meet the major categories of threat actors — including script kiddies, hacktivists, organised cybercrime groups, insiders, and nation-states — and explore how understanding an attacker's motives can help explain their methods.
You'll then examine how common attacks work, including phishing, social engineering, ransomware, DDoS, and injection attacks. You'll also learn why compromised credentials and legitimate access are often more useful to attackers than trying to break through technical barriers.
The course then turns to defence, covering:
The CIA Triad — Confidentiality, Integrity, and Availability
Defence in depth, least privilege, and Zero Trust
Authentication, multi-factor authentication, and passkeys
Encryption in transit and at rest
How a Security Operations Centre detects and responds to incidents
The course also introduces practical security measures you can consider for your own accounts and devices, including password managers, multi-factor authentication, timely software updates, backups, and the 3-2-1 backup rule.
Finally, you'll get an overview of cyber security career paths and the different areas of the field you may want to explore further.
Cyber security is a broad discipline, but understanding its core concepts doesn't require a technical background. This course is designed to give you a clear introduction to the subject and a foundation for further learning.
Who this course is for:
- Complete beginners who are curious about cyber security.
- Students deciding whether to enter the field and wanting a clear map of it.
- Non-technical professionals (HR, finance, marketing, operations) who handle sensitive data.
- Business owners and managers who need to understand digital risk.
- Anyone who wants to stop being an easy target online.
