PostgreSQL must generate audit records when categories of information (e.g., classification levels/security levels) are accessed.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity
V-261940	CD16-00-009600	SV-261940r1000825_rule		Medium

Description
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.

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. The DBMS (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, write, role' As the system administrator, reload the server with the new configuration: $ sudo systemctl reload postgresql- ${PGVER?}
