The correct answer is 'False'. Although the presence of intrusion detection sensors and automated log analysis tools might seem like preventive measures, they actually represent detective controls. Detective controls are not meant to prevent an incident but to detect and alert once an incident occurs or an anomaly is identified. Preventive measures, in contrast, would actively block or stop unauthorized actions before they happen, which in the described scenario, the systems are not doing; they are detecting and enabling a response after the fact.
