A corrective control is a control that aims to restore normal operations after a disruption or incident has occurred. Executing emergency response plans is an example of a corrective control, as it helps to mitigate the impact of an incident and resume business functions. Separating equipment development testing and production is a preventive control, as it helps to avoid errors or unauthorized changes in production systems.
Verifying duplicate calculations in data processing is a detective control, as it helps to identify errors or anomalies in data processing. Reviewing user access rights for segregation is also a detective control, as it helps to detect any violations of segregation of duties principles. References: ISACA, CISA Review Manual,
