What is the primary responsibility of a data owner compared to a data custodian?

The primary responsibility of a data owner is to have control over the data, which encompasses the authority to make decisions about who can access the data, how it can be used, and the overall management of that data. This includes establishing governance policies and ensuring that appropriate data protection measures are in place.

While a data custodian may implement the technical aspects and practical measures for data protection, such as configuring security protocols and managing the infrastructure that hosts the data, these activities are performed under the guidance and policies set forth by the data owner. Essentially, the data owner retains final control and decision-making authority, ensuring that the data is used and protected according to the organization’s goals and compliance requirements.

In contrast, the other options focus more on roles that might be shared or undertaken primarily by data custodians, such as adherence to data usage rules, granting technical permissions, and implementing specific protection measures. Therefore, these activities are aligned with the custodian's role, whereas the data owner's primary responsibility is to maintain overarching control over the data.
