The RUCKUS ICX router must be configured to drop all fragmented Internet Control Message Protocol (ICMP) packets destined to itself.

Description
Fragmented ICMP packets can be generated by hackers for denial-of-service (DoS) attacks such as Ping O' Death and Teardrop. It is imperative that all fragmented ICMP packets are dropped.

Who does this work

15 NICE work roles and 9 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-273606r1110918_chk)

Verify router management interfaces are configured to drop fragmented packets. Interface ethernet 1/1/1 ip access-group EXT_ACL in logging enable ip access-group frag deny If the router is not configured with a receive-path filter to drop all fragmented ICMP packets, this is a finding. Note: If the platform does not support the receive path filter, verify that all layer 3 interfaces have an ingress ACL to control what packets are allowed to be destined to the router for processing.

Fix Text (F-77602r1109839_fix)

Configure inbound ACLs to block fragmented packets destined to itself. ICX(config)#interface ethernet 1/1/1 ICX(config-if-e1000-1/1/1)#ip access-group EXT-ACL in logging enable ICX(config-if-e1000-1/1/1)#ip access-group frag deny
