Description
Routing protocol daemons are typically used on routers to exchange network topology information with other routers. If this software is used when not required, system network information may be unnecessarily transmitted across the network.

Who does this work

10 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-235025r991589_chk)

Verify the SUSE operating system is not performing IPv6 packet forwarding, unless the system is a router. Check to see if IPv6 forwarding is enabled using the following command: > sudo sysctl net.ipv6.conf.all.forwarding net.ipv6.conf.all.forwarding = 0 If the network parameter "ipv6.conf.all.forwarding" is not equal to "0" or nothing is returned, this is a finding.

Fix Text (F-38176r619345_fix)

Configure the SUSE operating system to not performing IPv6 packet forwarding by running the following command as an administrator: > sudo sysctl -w net.ipv6.conf.all.forwarding=0 If "0" is not the system's default value, add or update the following line in "/etc/sysctl.d/99-stig.conf": > sudo sh -c 'echo "net.ipv6.conf.all.forwarding=0" >> /etc/sysctl.d/99-stig.conf' > sudo sysctl --system
