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.
