CompTIA Security+ SY0-701 Practice Question

The motion sensors act as a Detective Control because they identify and alert to unauthorized activity. They do not prevent the incident from occurring but detect it so that appropriate action can be taken. Preventive Controls, like locks or access restrictions, are designed to stop unauthorized access from happening in the first place. Corrective Controls come into play after an incident to mitigate its impact, such as restoring data from backups. Deterrent Controls are intended to discourage potential attackers, like warning signs or visible security cameras.
