Teach common network vulnerabilities with an 80-slide IB Computer Science HL presentation for A2.4.2, first assessment 2027.
Explore how weaknesses in networks, software and human behaviour expose systems and data to attack.
Ten vulnerabilities and attack types covered
- DDoS attacks
- Insecure network protocols
- Malware
- Man-in-the-middle attacks
- Phishing
- SQL injection
- Cross-site scripting (XSS)
- Unpatched software
- Weak authentication
- Zero-day exploits
Includes learning objectives, a starter activity, explanations, diagrams, applied scenarios and checkpoints. Comparison activities help students distinguish commonly confused concepts such as SQL injection versus XSS, and unpatched software versus zero-day exploits.
Mixed IB-style scenarios, classification challenges and exit tickets support revision and practice using the Describe command term.
