The EDB Postgres Advanced Server must generate audit records when unsuccessful attempts to delete privileges/permissions occur.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity
V-69049	PPS9-00-011300	SV-83653r1_rule		Medium

Description
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.
