How does OAC ensure data security and governance?

The choice that highlights how OAC ensures data security and governance is correct because it emphasizes the integrated approach to security through role-based access control and adherence to data governance policies. Role-based security allows for defining user roles and permissions, ensuring that individuals can only access the data necessary for their roles, which minimizes the risk of unauthorized access and data breaches.

Additionally, support for data governance policies reinforces the standards and practices that guide how data is managed, ensuring compliance with regulations and framework requirements. This approach not only secures data but also maintains its integrity and usability for business intelligence purposes.

In comparison, the other options do not provide a comprehensive mechanism for ensuring security and governance. Relying solely on encryption methods, limiting access to certain networks, or promoting cloud storage does not encompass the broader requirements for effective data management and protection that role-based security and governance frameworks address.
