MariaDB must generate audit records when unsuccessful attempts to add privileges/permissions occur.
An XCCDF Rule
Description
<VulnDiscussion>Failed attempts to change the permissions, privileges, and roles granted to users and roles must be tracked. Without an audit trail, unauthorized attempts to elevate or restrict privileges could go undetected. In MariaDB, adding permissions is done via the GRANT command, or, in the negative, the REVOKE command. To aid in diagnosis, it is necessary to keep track of failed attempts in addition to the successful ones.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
