ISC2 CC Practice Question: Requires that two separate administrators approve…
An organization requires that two separate administrators approve and implement changes to firewall rules. This practice enforces which security principle?
⚠ Common exam trap
ISC2 often tests separation of duties by describing a scenario involving multiple people for a single task, and the trap is confusing it with least privilege, which focuses on limiting permissions rather than splitting responsibilities.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Separation of duties
Requiring two separate administrators to approve and implement firewall rule changes enforces separation of duties. This principle ensures that no single individual has the authority to both authorize and execute a change, reducing the risk of unauthorized modifications or errors. In firewall management, this prevents a single admin from introducing malicious or misconfigured rules without oversight.
