OSI Model Cheat Sheet

Concise summary of the OSI model layers, and the major protocols and devices you need to know to pass the CISSP exam.

In this cheat sheet, you’ll learn:

  • What each of the 7 layers of the OSI model focus on?
  • The critical protocols and devices at each layer.
  • Concise definitions for the protocols and devices.

You were able to take all those complex terms and definitions into very simple words and examples that helped me so much to not just value what we do as professionals, but also to help me think outside the box.
