The Nokia Border Gateway Protocol (BGP) router must be configured to reject outbound route advertisements for any prefixes that do not belong to any customers or the local autonomous system (AS).

Description
Advertisement of routes by an autonomous system for networks that do not belong to any of its customers pulls traffic away from the authorized network. This causes a denial of service (DoS) on the network that allocated the block of addresses and may cause a DoS on the network that is inadvertently advertising it as the originator. A misconfigured or compromised router within the Department of Defense Information Network (DODIN) IP core could redistribute Interior Gateway Protocol (IGP) routes into BGP, thereby leaking internal routes.

Who does this work

18 NICE work roles and 10 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.

This requirement is not applicable for the DODIN Backbone. Review the router configuration to verify a filter is defined to only advertise routes for prefixes that belong to any customers or the local AS. Use the command below to view the prefix list: - show router policy prefix-list "Customer Prefix" prefix 192.168.100.0/24 prefix-length-range 24-32 prefix 192.168.200.0/24 prefix-length-range 24-32 Use the command below to view the policy statement: - show router policy "Advertise Customer" entry 10 from prefix-list "Advertise Customer" exit action accept exit exit default-action drop exit Use the command below to verify the policy is applied to the eBGP group: - show router bgp group "eBGP" detail | match "Export Policy" Export Policy : Advertise Customer If the router is not configured to reject outbound route advertisements that belong to any customers or the local AS, this is a finding.

Fix Text (F-88374r1203960_fix)

Configure all eBGP routers to filter outbound route advertisements for prefixes that are not allocated to or belong to any customer or the local AS. Create a prefix list using the configuration below: - config>router>policy-options# begin - config>router>policy-options# prefix-list "Customer Prefix" - config>router>policy-options>prefix-list$ prefix 192.168.100.0/24 prefix-length-range 24-32 - config>router>policy-options>prefix-list$ prefix 192.168.200.0/24 prefix-length-range 24-32 - config>router>policy-options>prefix-list$ exit Create a policy statement using the configuration below: - config>router>policy-options# policy-statement "Advertise Customer" - config>router>policy-options>policy-statement$ entry 10 - config>router>policy-options>policy-statement>entry$ from prefix-list "Customer Prefix" - config>router>policy-options>policy-statement>entry$ action accept - config>router>policy-options>policy-statement>entry>action$ exit - router>policy-options>policy-statement$ default-action reject - config>router>policy-options>policy-statement$ exit - config>router>policy-options# commit - config>router>policy-options# exit Apply the routing policy to the BGP neighbor using the configuration below: - configure router bgp group "eBGP" export "Advertise Customer"
