ISC2 CC Practice Question: Is implementing a new access control system based…
An organization is implementing a new access control system based on the principle of least privilege. Which two of the following practices are essential to achieving least privilege? (Select TWO)
⚠ Common exam trap
ISC2 often tests that candidates confuse the principle of least privilege with account management practices like enabling/disabling accounts, or mistakenly think starting with full access and restricting later is acceptable, when in fact least privilege requires a default-deny posture.
Answer choices
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
✓
Review permissions regularly
Regular permission reviews are essential to maintaining least privilege over time. Users' roles and responsibilities change, and without periodic audits, excessive permissions can accumulate, violating the principle. This aligns with the NIST SP 800-53 AC-6 control for least privilege, which requires organizations to review user access rights at defined intervals.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Review permissions regularly
Why this is correct
Regular reviews help maintain minimal permissions by revoking unnecessary access.
- ✓
Use role-based access control
Why this is correct
RBAC assigns permissions based on job roles, aligning with least privilege.
- ✗
Grant users default full access and restrict later
Why it's wrong here
This approach gives excessive initial access, violating least privilege.
- ✗
Enable accounts after use
Why it's wrong here
Enabling accounts is not directly related to least privilege; disabling inactive accounts is more relevant.
- ✗
Provide write access to all users
Why it's wrong here
Granting write access to all users is excessive and violates least privilege.
