Changes in categories of information must be tracked. Without an audit trail, unauthorized access to protected data could go undetected. For detailed information on categorizing information, refer to FIPS Publication 199, Standards for Security Categorization of federal information and information systems, and FIPS Publication 200, Minimum Security Requirements for federal information and information systems.
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.
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.
PostgreSQL can be configured to audit these requests using pgaudit. Refer to supplementary content APPENDIX-B for documentation on installing pgaudit.
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'
As the system administrator, reload the server with the new configuration:
$ sudo systemctl reload postgresql-${PGVER?}
