Abstract: Regulating access to data in a database comprises binding data sensitivity labels to database table columns so that security policies can be applied at the column level rather than at the row level, without requiring creation of separate tables for the labeled columns and without associated join operations. In various embodiments, in response to a request for access to data in a particular column of a database table, column relevant data sensitivity labels and a user sensitivity permission are used to determine whether the requesting user is granted access to data in the labeled column. If the requesting user's sensitivity permission meets or exceeds the sensitivity of the requested data, then return of the data is allowed. The data sensitivity labels and the user sensitivity permission information may be managed in a central resource for access by multiple entities, such as multiple database servers.
