CRISC Risk Response and Reporting Practice Question
An organization is implementing a control to prevent unauthorized access to its critical database. The control must be designed to block access attempts in real time. Which type of control should be selected?
⚠ Common exam trap
Many exam-takers confuse detective controls (like monitoring or logging) with preventive controls, mistakenly thinking that detecting an attempt in real time is the same as blocking it, but detection does not stop the action from occurring.

Correct answer & explanation
✓
Preventive control
A preventive control is designed to block unauthorized access attempts in real time before they reach the critical database. Technologies such as a database firewall or network access control list (ACL) evaluate each request against a policy and drop the packet or terminate the session immediately, preventing the access from occurring. This aligns with the requirement for real-time blocking, which is the defining characteristic of a preventive control.
