What are the three methods of implementing controls?

The three methods of implementing controls are preventive, detective, and corrective controls. Preventive controls aim to reduce the likelihood of an undesirable event occurring by implementing measures such as policies and training. Detective controls focus on identifying and reporting incidents or anomalies after they occur, using tools like audits and monitoring systems. Corrective controls are put in place to respond to and rectify issues that have already happened, ensuring that similar problems do not recur in the future.
