🎯 Learning Intention

I will explain the CIA Triad (Confidentiality, Integrity, and Availability) and identify how each principle applies to real-world data protection.

✅ Success Criteria

• I can define each part of the CIA Triad.
• I can recognize how threats exploit weaknesses in one or more of these principles.
• I can describe practical steps to improve personal and organizational security.

🌍 Why We’re Learning This

Cybersecurity isn’t just a job field — it’s a mindset.

Every secure network, system, or account is built on the same three ideas: keep data private, keep it accurate, and keep it available.

⏰ Warm-Up (10 min)

“Imagine your phone was stolen. Which would worry you more — someone reading your messages, changing your files, or locking you out completely?”

Write your response, label it C, I, or A, and explain why.

Class poll results go on board: Which part of the CIA Triad do most people fear losing first?

🧠 Mini-Lesson (20 min) — The CIA Triad and Common Threats

1. Confidentiality — protecting sensitive data.
   • Threats: phishing, social engineering, password leaks.
   • Safeguards: MFA, encryption, least privilege.
2. Integrity — ensuring data isn’t altered without permission.
   • Threats: malware, tampering, insider modification.
   • Safeguards: hashing, version control, backups.
3. Availability — keeping systems up and accessible.
   • Threats: DDoS, power failure, hardware damage.
   • Safeguards: redundancy, failover, regular updates.
