The CompTIA Tech+ Study Guide (Exam FC0-U71, 3rd Edition, 2025) defines the least privilege model as:

“One of the key foundations of an authorization system is the least privilege model. This states that users should be granted only the least amount of access required to perform their jobs, and no more. This principle applies to computers, files, databases, and all other available resources.”

This concept ensures that a student cannot access restricted folders such as a teacher’s network folder, because their role does not require that level of access.
