PostgreSQL must generate audit records when unsuccessful attempts to modify 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. Modifying permissions is done via the GRANT and REVOKE commands. 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>
