The EDB Postgres Advanced Server must generate audit records when unsuccessful attempts to delete 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 individuals' and groups' privileges could go undetected. In an SQL environment, deleting permissions is typically done via 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>
