Audit Log Filter overview¶
The Audit Log Filter component allows you to monitor, log, and block a connection or query actively executed on the selected server.
Enabling the component produces a log file that contains a record of server activity. The log file has information on connections and databases accessed by that connection.
The component uses the mysql system database to store filter and user account data. Set the audit_log_filter.database variable at server startup to select a different database.
The AUDIT_ADMIN privilege is required to enable users to manage the Audit Log Filter component.
Privileges¶
Define the privilege at runtime at the startup of the server. The associated Audit Log Filter privilege can be unavailable if the component is not enabled.
AUDIT_ADMIN¶
This privilege is defined by the server and enables the user to configure the component.
AUDIT_ABORT_EXEMPT¶
This privilege allows queries from a user account to always be executed. An abort item does not block them. This ability lets the user account regain access to a system if an audit is misconfigured. The query is logged due to the privilege. User accounts with the SYSTEM_USER privilege have the AUDIT_ABORT_EXEMPT privilege.
Audit Log Filter tables¶
The Audit Log Filter component uses mysql system database tables in the InnoDB storage engine. These tables store user account data and filter data. When you start the server, change the component’s database with the audit_log_filter.database variable.
The audit_log_filter table stores the definitions of the filters and has the following column definitions:
Column name |
Description |
|---|---|
| NAME | Name of the filter |
| FILTER | Definition of the filter linked to the name as a JSON value |
The audit_log_user table stores account data and has the following column definitions:
Column name |
Description |
|---|---|
| USER | The account name of the user |
| HOST | The account name of the host |
| FILTERNAME | The account filter name |
