Fix Recommendation

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.

Logging must be enabled in order to capture the identity of any user/subject or process associated with an event. To ensure that logging is enabled, review supplementary content APPENDIX-C for instructions on enabling logging. 

To enable username, database name, process ID, remote host/port and application name in logging, as the database administrator (shown here as "postgres"), edit the following in postgresql.conf: 

$ sudo su - postgres 
$ vi ${PGDATA?}/postgresql.conf 
log_line_prefix = '< %m %u %d %p %r %a >' 

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

Check Contents

Check PostgreSQL settings and existing audit records to verify a user name associated with the event is being captured and stored with the audit records. If audit records exist without specific user information, this is a finding.

First, as the database administrator (shown here as "postgres"), verify the current setting of log_line_prefix by running the following SQL:

$ sudo su - postgres
$ psql -c "SHOW log_line_prefix"

If log_line_prefix does not contain %m, %u, %d, %p, %r, %a, this is a finding.
