While I'm sure there are many suitable options, in my experience Microsoft's "Fundamental" certifications do an excellent job of explaining the importance of user permissions. As the user identity is widely considered to be the new organizational boundary, it's imperative that IT staff understand the importance of providing the lowest level of permission to complete any given task, commonly referred to to as the "principle of least privilege." Developing an understanding of "defense in depth" is also quite important. If memory serves, these and other important concepts are covered in the AZ-900, MS-900 and SC-900 training. I would suggest that team members take the training, and then sit the exams for proof of their new knowledge.

To help my team understand the vital role of user permissions, I would start with a workshop that explains the concept in simple terms, using relatable examples to illustrate how permissions protect sensitive data and ensure operational integrity. Sharing real-life scenarios that demonstrate the consequences of mismanaged permissions, like data breaches, would emphasize their importance. I’d use visual aids, such as flowcharts, to clarify how permissions are structured. Additionally, providing hands-on practice with user permission settings in a controlled environment can reinforce learning. Finally, I’d create an open forum for questions, fostering a culture of security awareness and collaboration.
