Introduction to Cybersecurity
Cybersecurity is about protecting your devices, accounts, and data from digital attacks. It’s not only for “tech people” — it affects everyone who uses the internet.
Think of it like this
Cybersecurity is like locking your house: doors (passwords), alarm (2FA), CCTV (monitoring), and safe habits (awareness).
What are we protecting?
Key things worth protecting
- Your money (banking, shopping, transfers)
- Your identity (personal details, IDs, accounts)
- Your privacy (messages, photos, location)
- Your devices (phone, laptop, tablet)
- Your reputation (social accounts, impersonation)
Common threats (you’ll meet these in later topics)
- Phishing: fake messages that trick you into clicking or paying
- Malware: harmful software that steals data or damages devices
- Password attacks: guessing, re-use, and leaked passwords
- Scams: manipulation + urgency to make you act fast
Golden rule
If something is urgent, emotional, or too good to be true — slow down and verify.
Key takeaways
- Cybersecurity is for everyone online
- Protect money, identity, privacy, and devices
- Most attacks succeed because of human tricks, not ‘high-level hacking’
- Slow down, verify, and build safe habits
