The Juniper perimeter router must not be configured to redistribute static routes to an alternate gateway service provider into BGP or an IGP peering with the NIPRNet or to other autonomous systems.

Description
If the static routes to the alternate gateway are being redistributed into an Exterior Gateway Protocol or Interior Gateway Protocol to a NIPRNet gateway, this could make traffic on NIPRNet flow to that particular router and not to the Internet Access Point routers. This could not only wreak havoc with traffic flows on NIPRNet, but it could overwhelm the connection from the router to the NIPRNet gateway(s) and also cause traffic destined for outside of NIPRNet to bypass the defenses of the Internet Access Points.

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.

Check Text (C-253991r844006_chk)

This requirement is not applicable for the DODIN Backbone. Review the configuration of the router connecting to the alternate gateway and verify that redistribution of static routes to the alternate gateway is not occurring. Juniper routers use export policies to limit redistribution of routes. Verify a policy exists to filter route redistribution. [edit policy-options] policy-statement <name> { term 1 { from protocol static; then reject; } } Verify the export policy is applied to the EGP and/or IGP protocol. [edit protocols] bgp { export <policy-name>; group <group name> { type external; export <policy-name>; neighbor <address> { export <policy-name>; } } ospf { export <policy name>; } ospf3 { export <policy name>; } } Note: BGP supports export statements at the protocol level (global), the group level, and the neighbor level. Only the most specific policy is applied. If the static routes to the alternate gateway are being redistributed into BGP or any IGP peering with a NIPRNet gateway or another autonomous system, this is a finding.
