A compensating control is implemented when:

A compensating control is utilized when existing controls fail to adequately mitigate a risk. This means that certain threats may persist despite the presence of standard controls, either due to their inherent limitations or because they may not address specific vulnerabilities within a system or process. By implementing compensating controls, organizations aim to provide an alternative means of risk management that still maintains an acceptable level of security.

The focus on the inadequacy of normal controls highlights the necessity of finding an alternative solution that can fulfill the role of risk mitigation when traditional methods fall short. For instance, if specific access controls in a system are not effective due to certain operational constraints, implementing an additional layer of security, such as enhanced monitoring or revised user authentication measures, would be an example of a compensating control.

Other factors mentioned in the alternatives, like the complexity of controls, changing compliance requirements, and emerging security threats, do not directly justify the implementation of compensating controls. While these factors can influence risk management strategies, they do not inherently necessitate the creation of compensating controls in the same way that the inadequacy of standard controls does.
