Which term refers to the role of managing data on a day-to-day basis within an organization on behalf of the data owner/controller?

• A. Custodian
• B. Data Custodian
• C. Data Owner/Controller
• D. Data Classification

Answer: (B)

The day-to-day management of data on behalf of the data owner or controller is performed by the data custodian. This role handles operational tasks such as storing and organizing data, enforcing access controls, performing backups, maintaining data integrity, and applying security measures in line with the owner’s policies. The data owner/controller sets the overall purpose, permissible uses, and retention rules, while the custodian implements and operates those policies on a daily basis. Data classification, on the other hand, pertains to labeling data by sensitivity, not to ongoing data management. So the term that fits the described role is Data Custodian.
