Check: CISC-ND-000290
Cisco IOS XR Router NDM STIG:
CISC-ND-000290
(in versions v2 r3 through v1 r1)
Title
The Cisco router must produce audit records containing information to establish where the events occurred. (Cat II impact)
Discussion
In order to compile an accurate risk assessment and provide forensic analysis, it is essential for security personnel to know where events occurred, such as device hardware components, device software modules, session identifiers, filenames, host names, and functionality. Associating information about where the event occurred within the network device provides a means of investigating an attack; recognizing resource utilization or capacity thresholds; or identifying an improperly configured device.
Check Content
Review the deny statements in all ACLs to determine if the log-input parameter has been configured as shown in the example below. ipv4 access-list BLOCK_INBOUND 10 deny icmp any any log-input If the router is not configured with the log-input parameter after any deny statements to note where packets have been dropped via an ACL, this is a finding.
Fix Text
Configure the log-input parameter after any deny statements to provide the location as to where packets have been dropped via an ACL. RP/0/0/CPU0:R3(config)#ipv4 access-list BLOCK_INBOUND RP/0/0/CPU0:R3(config-ipv4-acl)#deny icmp any any log-input
