Exam Tips
- Firewall: Always mention it filters traffic based on RULES and uses criteria like source/destination/port
- Encryption: Emphasize that encrypted data is USELESS without the decryption key - that's why it's effective
- Authentication vs Authorisation: Authentication = WHO you are (login); Authorisation = WHAT you can do (permissions)
- MFA factors: Remember the THREE categories - something you know/have/are (not just "two passwords"!)
- Common question: "Describe how [method] protects against [threat]" - explain the MECHANISM clearly, not just "it protects"
- Defence in depth: Multiple layers of security are better than relying on one method
