The NSX Tier-0 Gateway router must be configured to use encryption for Open Shortest Path First (OSPF) routing protocol authentication.

Description
A rogue router could send a fictitious routing update to convince a site's perimeter router to send traffic to an incorrect or even a rogue destination. This diverted traffic could be analyzed to learn confidential information about the site's network or used to disrupt the network's ability to communicate with other networks. This is known as a "traffic attraction attack" and is prevented by configuring neighbor router authentication for routing updates. However, using clear-text authentication provides little benefit since an attacker can intercept traffic and view the authentication key. This would allow the attacker to use the authentication key in an attack. This requirement applies to all IPv4 and IPv6 protocols that are used to exchange routing or packet forwarding information; this includes all Interior Gateway Protocols (such as OSPF, Enhanced Interior Gateway Routing Protocol [EIGRP], and Intermediate System to Intermediate System [IS-IS]) and exterior gateway protocols (such as Border Gateway Protocol [BGP]), multiprotocol label switching (MPLS)-related protocols (such as Label Distribution Protocol [LDP]), and multicast-related protocols. Typically routing protocols must be setup on both sides so knowing the authentication key does not necessarily mean an attacker would be able to setup a rogue router and peer with a legitimate one and inject malicious routes.

Who does this work

7 NICE work roles and 5 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-265406r994568_chk)

If the Tier-0 Gateway is not using OSPF, this is Not Applicable. To verify OSPF areas are using authentication with encryption, do the following: From the NSX Manager web interface, go to Networking >> Connectivity >> Tier-0 Gateways. For every Tier-0 Gateway, expand the "Tier-0 Gateway". Expand "OSPF", click the number next to "Area Definition", and view the "Authentication" field for each area. If OSPF area definitions do not have the "Authentication" field set to "MD5" and a "Key ID" and "Password" configured, this is a finding.

Fix Text (F-69231r994567_fix)

To set authentication for OSPF area definitions, do the following: From the NSX Manager web interface, go to Networking >> Connectivity >> Tier-0 Gateways, and expand the target Tier-0 gateway. Expand "OSPF", click the number next to "Area Definition". Select "Edit" on the target OSPF Area Definition. Change the Authentication drop-down to MD5, enter a Key ID and Password, and then click "Save". Note: The MD5 password can have a maximum of 16 characters.
