Detective controls are security measures designed to identify and detect unauthorized activities or breaches within a system. They help organizations monitor their operations and ensure compliance with policies by providing alerts or reports when suspicious actions occur. Examples of detective controls include intrusion detection systems, security cameras, and audit logs. These controls play a crucial role in risk management by enabling timely responses to potential threats. By identifying issues after they occur, detective controls allow organizations to investigate incidents, assess damages, and implement corrective actions to prevent future occurrences.
