A control is a measure or action that is implemented to reduce the likelihood or impact of a risk event, or to enhance the benefits or opportunities of a risk event. A control owner is a person who is assigned the responsibility and authority for the design, implementation, operation, and maintenance of a control. The most appropriate person to be assigned ownership of a control is the individual accountable for monitoring control effectiveness, which is the process of measuring and evaluating the performance and compliance of the control. By assigning the control ownership to the individual accountable for monitoring control effectiveness, the organization can ensure that the control is aligned with the risk objectives, operates as intended, and delivers the expected results.

Data anonymization is the most important control to ensure the privacy of customer information when participating in an industry benchmarking study that involves providing customer transaction records for analysis. Data anonymization is the process of removing or modifying personally identifiable information (PII) from data sets, such as names, addresses, phone numbers, email addresses, etc., so that the data cannot be traced back to specific individuals. Data anonymization protects the confidentiality and privacy of customers, while still allowing for meaningful analysis and comparison of data. Nondisclosure agreements (NDAs), data cleansing, and data encryption are also useful controls, but they do not eliminate the risk of data breaches or unauthorized access to PII.

The most important element to update when an organization's risk appetite changes is the key risk indicators (KRIs). KRIs are metrics that provide an early warning of increasing risk exposure in various areas of the organization. They help to monitor the level of risk and to trigger risk responses when the risk exceeds the risk appetite. The risk appetite is the amount and type of risk that an organization is willing to accept in pursuit of its objectives. Risk reporting methodology, key performance indicators (KPIs), and risk taxonomy are other elements that may be updated, but they are not as important as the KRIs.
