EPAS-00-003600 - The role(s)/group(s) used to modify database structure and logic modules must be restricted to authorized users.
Information
Database structures include but are not necessarily limited to tables, indexes, storage, etc.Logic modules are objects such as stored procedures, functions, triggers, and links to software external to the DBMS, etc.
If the DBMS were to allow any user to make changes to database structure or logic modules, 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 must 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.
NOTE: Nessus has provided the target output to assist in reviewing the benchmark to ensure target compliance.
Solution
Revoke unauthorized privileges. The syntax is:REVOKE <privilege> ON <object> FROM <role>.
Example: REVOKE INSERT ON mytable FROM PUBLIC;
