MADB-10-010300 - MariaDB must generate audit records when unsuccessful attempts to modify security objects occur.

Information

Changes in the database objects (tables, views, procedures, functions) that record and control permissions, privileges, and roles granted to users and roles must be tracked. Without an audit trail, unauthorized changes to the security subsystem could go undetected. The database could be severely compromised or rendered inoperative.

To aid in diagnosis, it is necessary to keep track of failed attempts in addition to the successful ones.

NOTE: Nessus has provided the target output to assist in reviewing the benchmark to ensure target compliance.

Solution

The MariaDB Enterprise Audit plugin can be configured to audit these changes.

Update necessary audit filters to include query_event ALL. Example:

MariaDB> DELETE FROM mysql.server_audit_filters WHERE filtername = 'default';

MariaDB> INSERT INTO mysql.server_audit_filters (filtername, rule)
VALUES ('default',
JSON_COMPACT(
'{
'connect_event': [
'CONNECT',
'DISCONNECT'
],
'query_event': [
'ALL'
]
}'
));
