Definition
The Principle of Least Privilege (PoLP) states that each user, system or process should have only the permissions necessary to perform its assigned tasks.
Human Explanation
No person or system should have more access than it genuinely needs.
Why it Matters
Limiting permissions reduces the consequences of errors, account compromise and unauthorised actions.
Conceptual Boundary
PoLP does not mean preventing people from doing their work. It means providing the access required while limiting unnecessary exposure.
Practical Perspective
Regular permission review is as important as assigning permissions correctly in the first place.
