Corrective — Coupled with preventive and detective controls, corrective controls help mitigate damage once a risk has materialized. An organization can document its policies and procedures, enforcing them by means of warnings and employee termination when appropriate.
Detective control is an accounting term that refers to a type of internal control intended to find problems within a company's processes. Detective control may be employed in accordance with many different goals, such as quality control, fraud prevention and legal compliance.
Both types of controls are essential to an effective internal control system. From a quality standpoint, preventive controls are essential because they are proactive and emphasize quality. However, detective controls play a critical role by providing evidence that the preventive controls are functioning as intended.
