CD12-00-004400 - PostgreSQL must generate audit records when categorized information (e.g., classification levels/security levels) is accessed.

Information

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.

Solution

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.

Using pgaudit, the DBMS (PostgreSQL) can be configured to audit these requests. See 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, write, role'

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

$ sudo systemctl reload postgresql- ${PGVER?}
