DB2X-00-002800 - DB2 must limit privileges to change software modules, to include stored procedures, functions and triggers, and links to software external to DB2.

Information

If the system were to allow any user to make changes to software libraries, 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.

NOTE: Nessus has provided the target output to assist in reviewing the benchmark to ensure target compliance.

Solution

Use the appropriate variation of REVOKE (schema privileges) statement to remove the privileges from unauthorized users/roles/groups:
DB2> REVOKE <ALTERIN/CREATEIN/DROPIN> ON SCHEMA <schema-name> FROM <USER/GROUP/PUBLIC/ROLE>
