PostgreSQL must generate audit records for all direct access to the database(s).

An XCCDF Rule

Description

<VulnDiscussion>In this context, direct access is any query, command, or call to the DBMS that comes from any source other than the application(s) that it supports. Examples would be the command line or a database management utility program. The intent is to capture all activity from administrative and non-standard sources.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

Note: The following instructions use the PGDATA and PGVER environment variables. See supplementary content APPENDIX-F for instructions on configuring PGDATA and APPENDIX-H for PGVER.

To ensure that logging is enabled, review supplementary content APPENDIX-C for instructions on enabling logging. 

Using pgaudit PostgreSQL can be configured to audit these requests. See supplementary content APPENDIX-B for documentation on installing pgaudit. 
With pgaudit installed the following configurations should be made: 

$ sudo su - postgres 
$ vi ${PGDATA?}/postgresql.conf 

Add the following parameters (or edit existing parameters): 

pgaudit.log='ddl, role, read, write' 
log_connections='on' 
log_disconnections='on' 

Now, as the system administrator, reload the server with the new configuration: 

# SYSTEMD SERVER ONLY 
$ sudo systemctl reload postgresql-${PGVER?} 

# INITD SERVER ONLY 
$ sudo service postgresql-${PGVER?} reload

PostgreSQL must generate audit records for all direct access to the database(s).
