Which role is responsible for the confidentiality, integrity, availability, and privacy of information assets?

The role that is responsible for the confidentiality, integrity, availability, and privacy of information assets is the Data Owner. A Data Owner is typically the individual or entity that has ultimate responsibility for a particular set of data or information assets. This role entails making decisions about who can access the data, ensuring the appropriate security measures are in place, and defining how the data should be used and protected.

The Data Owner's responsibilities are holistic, encompassing not just the protection of the data (confidentiality and integrity) but also its availability and privacy. This means they ensure that data is accessible to authorized users when needed, while also implementing measures to safeguard sensitive information and comply with applicable regulations.

While other roles like Data Steward and Data Custodian have important functions in data management, they typically support the objectives set by the Data Owner rather than carry the overarching responsibility. The Privacy Officer focuses specifically on compliance with legal and regulatory standards related to privacy but may not cover all aspects of data integrity and availability associated with information assets. Therefore, the Data Owner is the most complete and appropriate answer for the role described in this context.
