What is the primary function of a data custodian?

1. To determine data processing purposes

2. To manage technical controls based on rules set by the data owner

3. To comply with data protection regulations

4. To assign access rights to data

The correct answer is: To manage technical controls based on rules set by the data owner

The primary function of a data custodian is to manage technical controls based on rules set by the data owner. Data custodians are responsible for the implementation and oversight of data-related infrastructure and security measures. They ensure that the data is stored, processed, and transmitted according to the policies and procedures defined by the data owner, who determines how the data should be handled and for what purposes. This role includes the responsibility to maintain the security of the data and to facilitate data management practices that protect integrity, confidentiality, and availability. The custodian focuses on the technical aspects, making sure that the systems and tools used to handle the data are properly configured and compliant with established security protocols. While compliance with data protection regulations and assigning access rights are important aspects of data management, they fall more under the purview of other roles, such as data owners or compliance officers. Thus, the essence of the data custodian's role is fundamentally about the management and implementation of technical control measures as guided by the policies set by the data owner.
