ISC2 CC Practice Question: A security analyst is reviewing logs and finds…
A security analyst is reviewing logs and finds that a user accessed files outside of their department. The user claims it was necessary for a project. Which principle should the analyst use to assess whether this was appropriate?
⚠ Common exam trap
ISC2 often tests the distinction between 'least privilege' (permissions assigned to a role) and 'need to know' (justification for accessing specific data at a specific time), causing candidates to pick 'least privilege' when the scenario involves a user who already has the permission but needs to justify the access.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Need to know
The 'need to know' principle restricts access to information based on the specific requirements of a user's role or project. In this scenario, the analyst must verify if the user's project actually required access to those specific files, not just if the user had the technical ability to access them. This principle is a subset of least privilege, focusing on data access rather than system permissions.
