Why it matters to you
- Your accounts, photos, and money are all protected by security you use every day — passwords, locks, and HTTPS.
- Understanding how they work helps you stay safe and spot when something is wrong.
A growing career
- Blue team defenders protect systems; red team attackers test them by trying to break in (with permission).
- Security is one of the fastest-growing areas in computing, with far more jobs than people to fill them.
Two sides, one skill set
- The same knowledge protects and attacks — so we always learn it ethically, to defend.
- We will write small programs that encrypt, hash, and crack — to understand both sides.
What you will learn
- Threats (malware, phishing, attacks) and the defences that stop them.
- Encryption, hashing, and how HTTPS keeps the web safe.
- Plus exam-ready coverage of the IGCSE and A-Level security topics. Let's get set up.
