Fix Recommendation

Configure the MySQL Database Server to audit for unsuccessful attempts to execute 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".

Check Contents

Review the system documentation to determine if MySQL Server is required to audit for unsuccessful attempts to execute privileged activities or other system-level access.

Check if MySQL audit is configured and enabled. The my.cnf file will set the variable audit_file.

To further check, 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.

Determine if rules are in place to capture the following types of commands related to permissions by running:

select * from mysql.audit_log_filter;

If the template SQL filter was used, it will have the name log_stig.

Review the filter values it will show filters for events of type of the field general_sql_command.str for the following SQL statement types:
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
