What is an example of a compensating control in the context of PCI DSS?

In the context of PCI DSS, a compensating control is defined as an alternative security measure that achieves the same level of security as the original requirement while addressing specific limitations or constraints faced by an organization. When a company cannot meet a specific PCI DSS requirement due to valid technical or business constraints, they may implement compensating controls that effectively mitigate the associated risks.

This aligns perfectly with the concept of compensating controls, as they are not just substitutes but must demonstrate that they fulfill the objective of the original requirement. For instance, if an organization cannot implement a specific technical requirement due to compatibility issues, they may employ a different solution that ensures cardholder data is protected to the same degree.

The other options do not fit this definition. Enhancing physical security or maintaining records is important for overall security and compliance, but they do not directly relate to compensating for a specific PCI DSS requirement. Similarly, while encryption is a critical aspect of securing cardholder data, it does not represent a compensating control but rather a technical measure meant to protect data in accordance with established standards.
