MYS8-00-004000 - The MySQL Database Server 8.0 must generate audit records for all privileged activities or other system-level access.

Information

Without tracking privileged activity, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one.

System documentation should include a definition of the functionality considered privileged.

A privileged function in this context is any operation that modifies the structure of the database, its built-in logic, or its security settings. This would include all Data Definition Language (DDL) statements and all security-related statements. In a SQL environment, it encompasses, but is not necessarily limited to:
CREATE
ALTER
DROP
GRANT
REVOKE
DENY

There may also be Data Manipulation Language (DML) statements that, subject to context, should be regarded as privileged. Possible examples in SQL include:

TRUNCATE TABLE;
DELETE, or
DELETE affecting more than n rows, for some n, or
DELETE without a WHERE clause;

UPDATE or
UPDATE affecting more than n rows, for some n, or
UPDATE without a WHERE clause;

any SELECT, INSERT, UPDATE, or DELETE to an application-defined security table executed by other than a security principal.

Depending on the capabilities of the DBMS and the design of the database and associated applications, audit logging may be achieved by means of Database Management System (DBMS) auditing features, database triggers, other mechanisms, or a combination of these.

Note that it is particularly important to audit, and tightly control, any action that weakens the implementation of this requirement itself, since the objective is to have a complete audit trail of all administrative activity.

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

Solution

Configure the MySQL Database Server to audit for all privileged activities or other system-level access.

Add the following events to the MySQL Server Audit:
grant
grant_roles
revoke
revoke_all
revoke_roles
drop_role
alter_user_default_role
create_role
drop_role
grant_roles
revoke_roles
set_role
create_user
alter_user
drop_user
alter_user
alter_user_default_role
create_user
drop_user
rename_user
show_create_user

See the supplemental file 'MySQL80Audit.sql'.
