The Cisco router must be configured to produce audit records containing information to establish the source of the events.

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.

Who does this work

6 NICE work roles and 5 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-216570r531085_chk)

Review the router configuration to verify that events are logged containing information to establish the source of the events as shown in the example below. ip access-list extended INGRESS_FILTER permit tcp any any established permit tcp host x.11.1.1 eq bgp host x.11.1.2 permit tcp host x.11.1.1 host x.11.1.2 eq bgp permit tcp any host x.11.1.5 eq www permit icmp host x.11.1.1 host x.11.1.2 echo permit icmp any any echo-reply … … … deny ip any any log-input Note: When the log-input parameter is configured on deny statements, the log record will contain the layer 2 address of the forwarding device for any packet being dropped. If the router is not configured to produce audit records containing information to establish the source of the events, this is a finding.

Fix Text (F-17801r287095_fix)

Configure the router to log events containing information to establish where the events occurred as shown in the example below. R5(config)#ip access-list extended INGRESS_FILTER … … … R5(config-ext-nacl)#deny ip any any log-input
