The Cisco ISE must generate a log record when an endpoint fails authentication.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity

Description
Failing the Cisco ISE assessment means that an unauthorized machine has attempted to access the secure network. Without generating log records that are specific to the security and mission needs of the organization, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one.
