Which of the following is the GREATEST impact as a result of the ongoing deterioration of a detective control?
The greatest impact as a result of the ongoing deterioration of a detective control is the increased number of false negatives in security logs. When detective controls deteriorate, their primary function of accurately identifying and logging incidents is compromised, leading to incidents being missed or not properly detected. This results in an increased number of false negatives, where actual security threats go unreported, endangering the overall security posture.
while option B (Decreased effectiveness of root cause analysis) could also be a consequence of deteriorating detective controls, it typically follows after the detection phase. If the detective control fails to detect incidents accurately (leading to increased false negatives), it undermines the ability to conduct effective root cause analysis because incidents are missed or not properly logged. Therefore, the deterioration of detective controls primarily impacts the accuracy and reliability of incident detection, resulting in an increased number of false negatives in security logs. This makes option A the correct answer.
