The perimeter router must be configured to block all packets with any IP options.

Description
Packets with IP options are not fast switched and henceforth must be punted to the router processor. Hackers who initiate denial-of-service (DoS) attacks on routers commonly send large streams of packets with IP options. Dropping the packets with IP options reduces the load of IP options packets on the router. The end result is a reduction in the effects of the DoS attack on the router and on downstream routers.

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-216980r945859_chk)

This requirement is not applicable for the DoDIN Backbone. Review the router configuration to determine if it will block all packets with IP options. If the router is not configured to drop all packets with IP options, this is a finding.

Fix Text (F-18208r382647_fix)

This requirement is not applicable for the DoDIN Backbone. Configure the router to drop all packets with IP options.
