The role(s)/group(s) used to modify database structure (including but not necessarily limited to tables, indexes, storage, etc.) and logic modules (stored procedures, functions, triggers, links to software external to the DBMS, etc.) must be restricted to authorized users.
If the DBMS were to allow any user to make changes to database structure or logic, then those changes might be implemented without undergoing the appropriate testing and approvals that are part of a robust change management process. Accordingly, only qualified and authorized individuals shall be allowed to obtain access to information system components for purposes of initiating changes, including upgrades and modifications. Unmanaged changes that occur to the database software libraries or configuration can lead to unauthorized or compromised installations.
Revoke unauthorized memberships in the DBMS modification group(s)/role(s).
Identify the group(s)/role(s) established for DBMS modification. Obtain the list of users in those group(s)/roles. Identify the individuals authorized to modify the DBMS. If unauthorized access to the group(s)/role(s) has been granted, this is a finding.
