Discussion

If the database management system (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.

Review accounts for direct assignment of administrative privileges. Connected as SYSDBA, run the query:

SELECT grantee, privilege
FROM dba_sys_privs
WHERE grantee IN 
(
SELECT username
FROM dba_users
WHERE username NOT IN 
(
'XDB', 'SYSTEM', 'SYS', 'LBACSYS',
'DVSYS', 'DVF', 'SYSMAN_RO',
'SYSMAN_BIPLATFORM', 'SYSMAN_MDS',

AND privilege NOT IN ('UNLIMITED TABLESPACE'
, 'REFERENCES', 'INDEX', 'SYSDBA', 'SYSOPER', 'CREATE SESSION'
)
ORDER BY 1, 2;

If any administrative privileges have been assigned directly to a database account, this is a finding.

The list of special accounts that are excluded from this requirement may not be complete. It is expected that the database administrator (DBA) will edit the list to suit local circumstances, adding other special accounts as necessary, and removing any that are not supposed to be in use in the Oracle deployment that is under review.
