Fix Recommendation

Note: The following instructions use the PGDATA and PGVER environment variables. Refer to APPENDIX-F for instructions on configuring PGDATA and APPENDIX-H for PGVER. To ensure logging is enabled, review supplementary content APPENDIX-C for instructions on enabling logging.

If logging is enabled, the following configurations must be made to log unsuccessful connections, date/time, username, and session identifier.

As the database administrator (shown here as "postgres"), edit postgresql.conf:

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

Edit the following parameters:

log_connections = on
log_line_prefix = '< %m %u %c: >'
pgaudit.log = 'read, write'

Where:
* %m is the time and date
* %u is the username
* %c is the session ID for the connection

As the system administrator, reload the server with the new configuration:

$ sudo systemctl reload postgresql-${PGVER?}

Check Contents

As the database administrator, verify pgaudit is enabled by running the following SQL:

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

If the output does not contain "pgaudit", this is a finding.

Verify that role, read, write, and ddl auditing are enabled:

$ psql -c "SHOW pgaudit.log"

If the output does not contain role, read, write, and ddl, this is a finding.
