Symantec ProxySG must produce audit records containing information to establish the source of the events.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity

Description
Without establishing the source of the event, it is impossible to establish, correlate, and investigate the events leading up to an outage or attack. In order to compile an accurate risk assessment and provide forensic analysis, security personnel need to know the source of the event. In addition to logging where events occur within the network, the audit records must also identify sources of events such as IP addresses, processes, and node or device names. This requirement does not apply to audit logs generated on behalf of the device itself (management).
