Question 86

Explanation

Correct Answer: A. High percentage of false negatives in the logs Explanation: The ongoing deterioration of a detective control can have various impacts, but the greatest impact is likely to be a high percentage of false negatives in the logs. Detective controls are designed to identify and detect security incidents or violations. They generate logs or alerts when specific events or patterns of behavior are observed. A high percentage of false negatives means that the detective control is failing to identify actual incidents or violations, leading to undetected security breaches or non-compliance. This can result in significant risks to the organization, as malicious activities or policy violations go unnoticed and are not properly addressed. Increased number of false positives in the logs (Option B) may create operational challenges and additional workload, but it does not have the same level of impact as undetected incidents. The decreased efficiency of preventive controls (Option C) and higher likelihood of unauthorized access incidents (Option D) are indirect consequences of the deteriorated detective control, but they do not directly represent the greatest impact. Therefore, the GREATEST impact resulting from the ongoing deterioration of a detective control is a high percentage of false negatives in the logs.
