A database security tool includes a user interface, a retrieval engine, an authorization engine, an alert engine, and an update engine. The user interface receives a request to add a row to a table in a database. The retrieval engine retrieves an authorization table from the database. The authorization table is separate from the table and indicates a plurality of users who are authorized to edit the table. The authorization engine determines whether the plurality of users includes the user. The alert engine communicates an alert indicating that the user is not authorized to add the row to the table. The update engine communicates, to the database, an update request in response to a determination that the plurality of users includes the user. The row is added to the table in response to the update request.
