The Cisco switch must be configured to generate an alert for all audit failure events.

Overview

Finding ID	Version	Rule ID	IA Controls	Severity
V-220497	CISC-ND-001000	SV-220497r604141_rule		Medium

Description
It is critical for the appropriate personnel to be aware if a system is at risk of failing to process audit logs as required. Without a real-time alert, security personnel may be unaware of an impending failure of the audit capability and system operation may be adversely affected. Alerts provide organizations with urgent messages. Real-time alerts provide these messages immediately (i.e., the time from event detection to alert occurs in seconds or less).

Review the Cisco switch configuration to verify that it is compliant with this requirement as shown in the example below: logging server 10.1.48.10 2 Note: The parameter 2 (critical) can replaced with a lesser severity level 3 through 6 (i.e. error, warning, notice, informational). Informational is the default severity level; hence, if the severity level is configured to informational, the parameter 7 will not be shown in the configuration. If the Cisco switch is not configured to generate an alert for all audit failure events, this is a finding.
