Data access control

Row and Column Access Control (RCAC) enables to control the security for certain rows and columns.

Db2® Warehouse has row and column access control capability, which is known as fine-grained access control. RCAC controls access to a table at the row or column level. It doesn't matter how a table is accessed via SQL, the table data is always protected. The enforcement is data-centric and requires no application changes. You can use Row and Column Access Control to ensure that your users only have access to the data required for their work. Columnar masking is also available to mask return values on certain columns, depending on the user or group.
