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.

Configure PostgreSQL to produce audit records when unsuccessful attempts to modify categories of information occur.

To ensure that logging is enabled, review supplementary content APPENDIX-C for instructions on enabling logging. All denials are logged when logging is enabled.

With pgaudit installed the following configurations can be made:

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

Add the following parameters (or edit existing parameters):

pgaudit.log='ddl, role, read, write'

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

$ sudo systemctl reload postgresql-${PGVER?}

Check Contents

First, 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.

Next, 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.
