Discussion

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.

Check Content

At the command prompt, execute the following command:

# /opt/vmware/vpostgres/current/bin/psql -U postgres -c "\du;"

If the accounts other than "postgres" and "vc" have create privileges, this is a finding.

Fix Text

At the command prompt, execute the following command:

# /opt/vmware/vpostgres/current/bin/psql -U postgres -c "REVOKE ALL PRIVILEGES FROM <user>;"

Replace <user> with the account discovered during the check.
