Fix Recommendation

Configure the switch to log events containing information to establish where the events occurred as shown in the example below:

SW1(config)#ip access-list extended INGRESS_FILTER
…
…
…
SW1(config-ext-nacl)#deny ip any any log-input

Check Contents

Review the switch configuration to verify that events are logged containing information to establish where the events occurred as shown in the example below:

ip access-list extended INGRESS_FILTER
permit tcp any any established
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 interface where the ingress packet has been dropped.

If the switch is not configured to produce audit records containing information to establish to establish where the events occurred, this is a finding.
