CISSP Exam - Question 341


Which of the following is the MOST effective corrective control to minimize the effects of a physical intrusion?

Show Answer
Correct Answer: A

The most effective corrective control to minimize the effects of a physical intrusion is rapid response by guards or police to apprehend a possible intruder. Corrective controls are designed to take action after an event has occurred in order to minimize its impact and prevent recurrence. While alarms, bright lighting, and videotaping serve as deterrent, detective, or preventive controls, they do not directly mitigate the impact of an intrusion once it has begun. Apprehending the intruder directly addresses the situation and minimizes further potential damage or loss.

Only "A" will give you a CORRECTIVE control. The other options are mostly deterrents.

A appears to be the only corrective control. "Corrective controls are designed to respond to errors or events in order to take action to minimize risk of future occurrence." https://sharedassessments.org/glossary/corrective-control/ Police and guards responding is the corrective control (which means a response) Lights and sounds appear to be detective and deterrent: https://blog.eduonix.com/networking-and-security/learn-different-types-security-controls-cissp/

A. Rapid response by guards or police to apprehend a possible intruder.........A. is the only corrective control among the options provided. The rest are deterrent controls.

I dont know if the questions are really tricky, but if you read the question, minimize the effects of of physical intrusion (does it mean the physical intrusions already happened and based on the corrective control we are finding the best deterrent control moving further?) in this case the answer would be A based on the CISSP training. in other words, the most effective corrective control is to find a preventive control.

I almost went with D but its asking for a CORRECTIVE control so this means the other controls already failed. The other controls are detective, preventive, and deterrents

Corrective controls are designed to respond to and mitigate the impact of an incident after it has occurred. The goal is to minimize damage and restore normal operations as quickly as possible. A. Rapid response by guards or police is a corrective action — it addresses the incident (the intrusion) after detection, aiming to contain or neutralize the threat. This is the MOST effective in minimizing the actual impact of the intrusion.
