The Juniper router must be configured to have Internet Control Message Protocol (ICMP) redirect messages disabled on all external interfaces.

Description
The ICMP supports IP traffic by relaying information about paths, routes, and network conditions. Routers automatically send ICMP messages under a wide variety of conditions. Redirect ICMP messages are commonly used by attackers for network mapping and diagnosis.

Who does this work

12 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-217024r855892_chk)

Review the device configuration to determine if it has been configured to ensure the router does not send ICMP Redirect messages out to any external interface. interfaces { ge-1/0/0 { unit 0 { family inet { no-redirects; address 11.1.12.2/24; } } } ge-1/1/0 { unit 0 { family inet { no-redirects; address 11.1.23.2/24; } } } If ICMP Redirect messages are enabled on any external interfaces, this is a finding.

Fix Text (F-18251r296941_fix)

Disable ICMP redirects on all external interfaces as shown in the example below. [edit interfaces] set ge-1/0/0 unit 0 family inet no-redirects set ge-1/1/0 unit 0 family inet no-redirects
