A compensating control is a control that is implemented to reduce the risk exposure when the primary control is not feasible or cost-effective. A compensating control may not directly address the root cause of the risk, but it can provide an alternative or supplementary way of mitigating the risk. A residual risk is the risk that remains after the risk response has been implemented. A residual risk can be accepted, monitored, or further reduced depending on the risk tolerance and appetite of the organization. During a risk assessment, a risk practitioner is a person who is responsible for identifying and analyzing the potential sources and consequences of risk events. When a risk practitioner learns that an IT risk factor is adequately mitigated by compensating controls in an associated business process, the action that would enable the most effective management of the residual risk is to schedule periodic reviews of the compensating controls' effectiveness, which means to measure and evaluate the performance and compliance of the compensating controls on a regular basis. By scheduling periodic reviews of the compensating controls' effectiveness, the risk practitioner can ensure that the compensating controls are stilloperating as intended, and that they are delivering the expected results. The risk practitioner can also identify any gaps or weaknesses in the compensating controls, and recommend any improvements or adjustments as needed.
