The Data Steward is responsible for ensuring the classification, protection, use, and quality of that data, in line with the Data Governance standards set by the Data Owner. What Is a Data Custodian?

The data owner is responsible for the data within an organization. This role involves understanding the value, sensitivity, and regulatory requirements of the data. Data owners are typically responsible for classifying data based on these factors and ensuring that appropriate measures are taken to protect the data according to its classification. Data owners are in the best position to understand the context and requirements related to the data they manage, making them the most suitable for ensuring compliance with external requirements.

The Data Steward is the most appropriate role for classifying systems and data in accordance with external requirements due to their specific responsibility for managing data classification, quality, and compliance. They collaborate closely with Data Owners to ensure that data is classified accurately based on sensitivity and regulatory requirements, making them well-suited for ensuring data is managed appropriately throughout its lifecycle within the organization. Data owner is a critical role in data governance, responsible for making decisions about data assets, including defining data classification policies, access controls, and usage guidelines. While Data Owners have the authority to set policies regarding data classification, they typically delegate the operational task of classifying data to Data Stewards.
