Creating mnemonics is a great way to remember important concepts, especially for Domain 4 of the CISSP exam, which covers "Communication and Network Security."
Here are some mnemonics (which I personally recommend and have used for sure) to help you remember key concepts:
OSI Model Layers (7 layers): "Please Do Not Throw Sausage Pizza Away"
- Physical
- Data Link
- Network
- Transport
- Session
- Presentation
- Application
TCP/IP Model Layers (4 layers): "Apples Taste So Nice"
- Application
- Transport
- Internet
- Network Interface
Firewall Types: "Windy People Never Jump"
- Web Application Firewalls
- Packet Filtering
- Network Address Translation
- Jump Servers
IPSec Protocols: "Ethan Always Helps"
- Encapsulating Security Payload (ESP)
- Authentication Header (AH)
- Handshake Protocols
Cryptography Concepts: "Cindy Has Integrity, Confidentiality, and Authenticity"
- Confidentiality
- Hashing
- Integrity
- Confidentiality
- Authenticity
Common Network Attacks: "Dad's SIR"
- DDoS (Distributed Denial of Service)
- Sniffing
- IP Spoofing
- Rebroadcast
Using these mnemonics, you can more easily recall the essential concepts of Domain 4 for your CISSP exam preparation.
