Description
Without tracking privileged activity, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one. System documentation should include a definition of the functionality considered privileged. A privileged function in this context is any operation that modifies the structure of the database, its built-in logic, or its security settings. This would include all Data Definition Language (DDL) statements and all security-related statements. In an SQL environment, it encompasses, but is not necessarily limited to: CREATE ALTER DROP GRANT REVOKE Note that it is particularly important to audit, and tightly control, any action that weakens the implementation of this requirement itself, since the objective is to have a complete audit trail of all administrative activity. To aid in diagnosis, it is necessary to keep track of failed attempts in addition to the successful ones.

Check Text ( C-69539r2_chk )
Execute the following SQL as enterprisedb: SHOW edb_audit_statement; If the result is not "all" or if the current setting for this requirement has not been noted and approved by the organization in the system documentation, this is a finding.

Fix Text (F-75251r3_fix)
Execute the following SQL as enterprisedb: ALTER SYSTEM SET edb_audit_statement = 'all'; SELECT pg_reload_conf(); or Update the system documentation to note the organizationally approved setting and corresponding justification of the setting for this requirement.
