EP11-00-003600 – 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 EDB Postgres Advanced Server, etc.) must be restricted to authorized users.

Details

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 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 not performed this check. Please review the benchmark to ensure target compliance.

Solution

Revoke unauthorized privileges.

The syntax is:
REVOKE ON FROM .

Example:
REVOKE INSERT ON a FROM PUBLIC;

See PostgreSQL documentation for details.
