What type of access control allows sensitive data to be hidden from unauthorized users by logically dividing a database?

View-Based Access Controls are designed to restrict access to specific data within a database by creating virtual views that include only the data that users are authorized to see. This method effectively hides sensitive information from unauthorized users by defining and implementing logical divisions within the database, typically through the use of SQL views.

When using view-based access controls, administrators can define different views for different roles or users. Each view can present a tailored subset of the underlying data tables, ensuring that users only interact with the information they need for their role while sensitive data remains concealed. This approach enhances data security and privacy without the need for duplicating the data or creating multiple copies of the database.

While other options like row-level security, field-level security, and role-based access control also deal with access management, they operate at different granularity or apply different strategies for managing permissions. Row-level security focuses specifically on controlling access at the individual row level in a table, field-level security applies to specific fields or columns within a row, and role-based access control is more about assigning permissions based on the user's role rather than creating logical views that restrict visibility of sensitive data.
