Determine if an audit is configured and enabled. The my.cnf file will set the variable audit_file. Review the my.cnf file for the following entries: [mysqld] plugin-load-add=audit_log.so audit-log=FORCE_PLUS_PERMANENT If these entries are not present. This is a finding. Execute the following query: SELECT PLUGIN_NAME, PLUGIN_STATUS FROM INFORMATION_SCHEMA.PLUGINS WHERE PLUGIN_NAME LIKE 'audit%'; The status of the "audit_log plugin" must be "active". If it is not "active", this is a finding. Review audit filters and associated users by running the following queries: SELECT `audit_log_filter`.`NAME`, `audit_log_filter`.`FILTER` FROM `mysql`.`audit_log_filter`; SELECT `audit_log_user`.`USER`, `audit_log_user`.`HOST`, `audit_log_user`.`FILTERNAME` FROM `mysql`.`audit_log_user`; All currently defined audits for the MySQL server instance will be listed. If no audits are returned, this is a finding.
